Aims: The atherosclerotic profile and advanced plaque subtype burden in symptomatic patients ≤45 years old have not been established. This study aimed to assess the prevalence and predictors of coronary artery calcium (CAC), plaque subtypes, and plaque burden by coronary computed tomography angiography (CCTA) in symptomatic young patients., Methods and Results: We included 907 symptomatic young patients (18-45 years) from Montefiore undergoing CCTA for chest pain evaluation. Prevalence and predictors of CAC, plaque subtypes, and burden were evaluated using semi-automated software. In the overall population (55% female and 44% Hispanic), 89% had CAC = 0. The likelihood of CAC or any plaque by CCTA increased with >3 risk factors {RFs, odds ratio [OR] 7.13 (2.14-23.7) and OR 10.26 (3.36-31.2), respectively}. Any plaque by CCTA was present in 137 (15%); the strongest independent predictors were age ≥35 years [OR 3.62 (2.05-6.41)] and family history of premature coronary artery disease (FHx) [OR 2.76 (1.67-4.58)]. Stenosis ≥50% was rare (1.8%), with 31% of those having CAC = 0. Significant non-calcified plaque (NCP, 37.2%) and low-attenuation plaque (LAP, 4.24%) burdens were seen, even in those with non-obstructive stenosis. Among patients with CAC = 0, 5% had plaque, and the only predictor of exclusively NCP was FHx [OR 2.29 (1.08-4.86)]., Conclusion: In symptomatic young patients undergoing CCTA, the prevalence of CAC or any coronary atherosclerosis was not negligible, and the likelihood increased with RF burden. The presence of coronary stenosis ≥50% was rare and most often accompanied by CAC >0, but there was a significant burden of NCP and LAP even within the non-obstructive group., Competing Interests: Conflict of interest: P.P., and D.L. are supported by grants from Amgen and Philips.

Objective: Epicardial adipose tissue (EAT) is implicated in the pathogenesis and progression of coronary artery disease (CAD). Limited data exists on the interplay between EAT and atherosclerosis in young individuals. Our study aims to explore the relationship between EAT and CAD in a young cohort., Methods: All young (18-45 years) patients without prior CAD, referred for coronary computed tomography angiography (CCTA) from 2016 to 2022 were included. EAT volume and coronary artery calcium (CAC) were calculated from dedicated non-contrast scans. Coronary plaque presence, extent, and volume were quantified from CCTA. Multivariable logistic regression models for the presence of CAD, defined as any coronary atherosclerosis, were performed., Results: Overall, 712 patients (39±4.8 years, 54 % female) with 45 % Hispanic, and 21 % non-Hispanic Black were included. Patients with CAD had higher EAT volume than those without (80.80 mL ± 36.00 vs 55.16 mL ± 27.92; P < 0.001). In those with CAC=0, higher EAT was associated with the presence of CAD compared to lower EAT volume ( P < 0.001). An EAT volume >76 mL was associated with higher CAC ( P < 0.001), segment involvement score ( P < 0.001), and quantitative total, non-calcified, and low-attenuation plaque volumes ( P < 0.002). At multivariable analysis, EAT volume (per 10 mL, OR: 1.21; 95 %CI: 1.12-1.30; P < 0.0001) was independently associated with the presence of CAD., Conclusion: In a diverse cohort of young adults without history of CAD and undergoing a clinically indicated CCTA, EAT volume was independently associated with the presence of CAD. Our findings highlight EAT potential as a novel marker for CAD risk-assessment and a potential therapeutic target in young patients., Competing Interests: Annalisa Filtz, Daniel Lorenzatti, and Leandro Slipczuk are supported by institutional grants from Amgen and Philips.

Previous research indicates varying stroke rates after mitral valve (MV) interventions. This study aimed to compare postprocedural stroke risks after transcatheter and surgical MV interventions. Electronic databases were searched from inception to February 2024 for studies comparing stroke rates after mitral transcatheter edge-to-edge repair (mTEER), surgical MV repair/replacement, or guideline-directed medical therapy (GDMT). Primary end points were all-time and early (<30 days) stroke. Secondary outcomes included new-onset atrial fibrillation and 1-year all-cause mortality. A frequentist network meta-analysis was employed to compare outcomes. The network meta-analysis included 18 studies (3 randomized controlled trials and 15 observational), with 51,703 patients. mTEER was associated with a decreased risk of all-time (odds ratio [OR] 0.61, 95% confidence interval [CI] 0.41 to 0.89) and early stroke (OR 0.41, 95% CI 0.33 to 0.51) compared with surgery, and a similar risk of all-time (OR 1.54, 95% CI 0.76 to 3.12) and early stroke (OR 2.12, 95% CI 0.53 to 8.47) compared with GDMT. Conversely, surgery was associated with an increased risk of all-time (OR 2.55, 95% CI 1.17 to 5.57) and early stroke (OR 5.15, 95% CI 1.27 to 20.84) compared with GDMT. There were no statistically significant differences in the risk of new-onset atrial fibrillation (OR 0.38, 95% CI 0.11 to 1.31) and 1-year all-cause mortality (OR 1.43, 95% CI 0.91 to 2.24) between mTEER versus surgery. In conclusion, mTEER was associated with a lower risk of stroke and similar risks of new-onset atrial fibrillation and 1-year mortality compared with surgical MV interventions. Further studies are needed to understand the mechanisms of stroke and to determine strategies to reduce stroke risk after MV interventions., Competing Interests: Declaration of competing interest Dr. Khera is a consultant and proctor for Medtronic, consultant and proctor for Abbott Structural Heart, consultant for Terumo and W.

The effectiveness of intravascular ultrasound (IVUS) with angiography compared with angiography guidance alone in treating aortic conditions, such as dissections, aneurysms, and blunt traumatic injuries, remains unclear. This systematic review and meta-analysis evaluates the current literature for IVUS use during thoracic endovascular aortic repair (TEVAR) and abdominal endovascular aortic repair (EVAR). A comprehensive search of MEDLINE, EMBASE, and Cochrane CENTRAL databases was conducted in March 2024 adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies comparing outcomes of TEVAR/EVAR with and without IVUS were identified. The outcomes of interest included contrast volume, fluoroscopy and procedural time, perioperative endoleak, and reinterventions and all-cause mortality during follow-up. Data with 95% confidence intervals (CIs) were extracted. Pooled analysis was performed using a random-effect model. Subgroup analysis was performed stratified by the condition being treated. Risk of bias was assessed using the Newcastle-Ottawa Scale for observational studies. A total of 4,219 patients (n = 2,655 IVUS and n = 1,564 non-IVUS) from 9 observational studies were included. The IVUS group exhibited a reduction in contrast agent volume (weighted mean difference -34.65 mL, 95% CI -54.73 to -14.57) and fluoroscopy time (weighted mean difference -6.13 minutes, 95% CI -11.10 to -1.15), with no difference in procedural time. The perioperative type I and III endoleak occurrences were similar (risk ratio 2.36, 95% CI 0.55 to 10.11; risk ratio 0.72, 95% CI 0.09 to 5.77, respectively). Reintervention and mortality during follow-up were comparable (hazard ratio 0.80, 95% CI 0.33 to 1.97; hazard ratio 0.75, 95% CI 0.47 to 1.18, respectively). All the included studies had small risks of bias. In conclusion, this meta-analysis provides evidence that IVUS enables the safe deployment of TEVAR/EVAR with reduced contrast agent and radiation exposure., Competing Interests: Declaration of competing interest Dr. Secemsky is supported in part by K23HL150290; and receives consulting fees from Abbott, Bayer, BD, Boston Scientific, CSI, Medtronic, Philips, Shockwave, and VentureMed.

Mitral regurgitation is one of the most prevalent valvulopathies with a disease burden that incurs significant healthcare costs globally. Surgical repair of the posterior mitral valve leaflet is a standard treatment, but approaches for repairing the anterior mitral valve leaflet are not widely established. Since anterior leaflet involvement is less common and more difficult to repair, fewer studies have investigated its natural history and treatment options. In this review, we discuss surgical techniques for repairing the anterior leaflet and their outcomes, including survival, reoperation, and recurrence of regurgitation. We show that most patients with mitral regurgitation from the anterior leaflet can be repaired with good outcomes if performed at centers with expertise. Additionally, equal consideration for early repair should be given to patients with mitral regurgitation from both anterior and posterior pathology. However, more studies to better evaluate the efficacy and safety of anterior mitral valve leaflet repair are needed., (Copyright © 2024 Hellenic Society of Cardiology. Published by Elsevier Inc.

Due to fungal diseases that threaten immunocompromised patients, along with the limited availability of antifungal agents, there is an urgent need for new antifungal compounds to treat fungal infections. Here, we aimed to identify potential antifungal drugs from natural products using the fission yeast Schizosaccharomyces pombe as a model organism since it shares many features with some pathogenic fungi. Here, we identified tubeimoside I (TBMS1), an extract from Chinese herbal medicine, that showed strong antifungal activity against S. pombe . To gain insight into the underlying mechanism, we performed transcriptomics analyses of S. pombe cells exposed to TBMS1. A significant proportion of the differential expressed genes were involved in cell wall organization or biogenesis. Additionally, TBMS1 treatment of S. pombe cells resulted in pleiotropic phenotypes, including increased sensitivity to β-glucanase, enhanced calcineurin activity, translocation of GFP-Prz1 to the nucleus, as well as enhanced dephosphorylation of Prz1, suggesting that TBMS1 disrupted cell wall integrity of S. pombe cells. Notably, calcofluor staining showed that abnormal deposits of cell wall materials were observed in the septum and cell wall of the TBMS1-treated cells, which were further corroborated by electron microscopy analysis. We also found that oxidative stress might be involved in the antifungal action of TBMS1. Moreover, we confirmed the antifungal activities of TBMS1 against several clinical isolates of pathogenic fungi. Collectively, our findings suggest that TBMS1, a novel antifungal compound, exerts its antifungal activity by targeting cell walls, which may pave the way for the development of a new class of antifungals., Importance: Fungal infections pose a serious threat to public health and have become an emerging crisis worldwide. The development of new antifungal agents is urgently needed. Here, we identified compound tubeimoside I (TBMS1) for the first time showing strong antifungal activity, and explored the underlying mechanisms of its antifungal action by using the model yeast Schizosaccharomyces pombe . Notably, we presented multiple evidence that TBMS1 exerts its antifungal activity through targeting fungal cell walls. Moreover, we verified the antifungal activities of TBMS1 against several pathogenic fungi. Our work indicated that TBMS1 may serve as a novel antifungal candidate, which provides an important foundation for designing and developing new cell wall-targeting agents for combating life-threatening fungal infections., Competing Interests: The authors declare no conflict of interest.

Background: Evidence on the comparative outcomes following percutaneous microaxial ventricular assist devices (pVAD) versus intra-aortic balloon pump for nonacute myocardial infarction cardiogenic shock is limited., Methods and Results: We included 704 and 2140 Medicare fee-for-service beneficiaries aged 65 to 99 years treated with pVAD and intra-aortic balloon pump, respectively, for nonacute myocardial infarction cardiogenic shock from 2016 to 2020. Patients treated using pVAD compared with those treated using intra-aortic balloon pump were more likely to be concurrently treated with mechanical ventilation, renal replacement therapy, and blood transfusions. We computed propensity scores for undergoing pVAD using patient- and hospital-level factors and performed a matching weight analysis. The use of pVAD was associated with higher 30-day mortality (adjusted odds ratio, 1.92 [95% CI, 1.59-2.33]) but not associated with in-hospital bleeding (adjusted odds ratio, 1.00 [95% CI, 0.81-1.24]), stroke (adjusted odds ratio, 0.91 [95% CI, 0.56-1.47]), sepsis (OR, 0.91 [95% CI, 0.64-1.28]), and length of hospital stay (adjusted mean difference, +0.4 days [95% CI, -1.4 to +2.3]). A quasi-experimental instrumental variable analysis using the cross-sectional institutional practice preferences showed similar patterns, though not statistically significant (adjusted odds ratio, 1.38; 95% CI, 0.28-6.89)., Conclusions: Our investigation using the national sample of Medicare beneficiaries showed that the use of pVAD compared with intra-aortic balloon pump was associated with higher mortality in patients with nonacute myocardial infarction cardiogenic shock. Providers should be cautious about the use of pVAD for nonacute myocardial infarction cardiogenic shock, while adequately powered high-quality randomized controlled trials are warranted to determine the clinical effects of pVAD.

Introduction: Thoracic endovascular aortic repair (TEVAR) has gained preference over open surgical repair (OSR) as the intervention of choice for patients with descending thoracic aortic aneurysm (DTA). This study aimed to compare the outcomes of patients with DTA undergoing OSR and TEVAR with contemporary findings., Evidence Acquisition: A comprehensive search of MEDLINE and EMBASE databases was conducted to identify relevant randomized controlled trials or studies utilizing propensity-score analysis or reporting risk-adjusted outcomes. The search was performed up until March 2023., Evidence Synthesis: Eight studies met the inclusion criteria, including 4 studies using propensity-score matching and four studies reporting risk-adjusted outcomes, comprising 14,873 patients with DTA undergoing OSR (N.=10,882) and TEVAR (N.=3991). Operative mortality was similar between the two interventions (odds ratio 0.92, 95% CI 0.70-1.21, P=0.57, I 2 =0%). However, overall long-term mortality was significantly higher after TEVAR compared to OSR (Hazard Ratio [HR] 1.30, 95% CI 1.05-1.59, P=0.01, I 2 =0%). Phase-specific analysis revealed comparable risks of mortality within 1 year and between one and two years after interventions, while the risk of mortality was significantly higher after TEVAR compared to OSR beyond two years (HR 1.77, 95% CI, 1.19-2.63, P=0.01. I 2 =0%)., Conclusions: This study demonstrated comparable operative mortality between OSR and TEVAR, but higher long-term mortality associated with TEVAR in patients with DTA. The phase-specific analysis highlighted the survival advantage of OSR beyond 2 years. These findings suggest a need for reconsidering OSR indications in the management of DTA.

Background: Dialysis practice has a particularly high environmental impact, including responsible for carbon emissions and climate change. Insufficient research has been conducted on environmental sustainability activities in dialysis therapy in Japan., Methods: We conducted an online Green Survey comprising 30 question items based on a previously conducted survey in Australia. Between August and September 2023, this was sent to members of the Japanese Association of Dialysis Physicians, including hospital and clinic physicians, working across 885 dialysis facilities in Japan., Results: In total, 255 (29%) facilities responded to the survey. More than half of the facilities (n = 157; 61.6%) responded that they did not have a strategy, policy, or action plan for environmental sustainability. In four-fifths of the facilities (n = 208; 81.6%), no "green team" or committee had been formed to promote environmental protection. By contrast, most of the surveyed facilities had emergency strategies for natural disasters, such as covering for patient visits and staff commuting during extreme weather conditions (n = 169; 66.3%), water shortages (n = 159; 62.4%), and power outages (n = 188; 73.7%)., Conclusions: Following the UK, Australia and New Zealand, and Portugal, this is the fourth Green Survey to be conducted, and the first on environmental sustainability among kidney health-care providers in Japan. The results indicated that daily activities for environmental protection are still lacking at many facilities, even though the management of dialysis treatment during a natural disaster is well conducted., (© 2024.

Background: Spontaneous coronary artery dissection (SCAD) is an underdiagnosed cause of acute coronary syndrome, particularly in younger women. Due to limited information about SCAD, case reports and case series can provide valuable insights into its features and management. This study aimed to comprehensively evaluate the features of SCAD patients who experienced psychophysical stress before the SCAD event., Methods: We conducted an electronic search of PubMed, Scopus, and Web of Science from inception until January 7, 2023. We included case reports or series that described patients with SCAD who had experienced psychophysical stress before SCAD. Patients with pregnancy-associated SCAD were excluded from our analysis., Results: In total, we included 93 case reports or series describing 105 patients with SCAD. The average patient age was 44.29 ± 13.05 years and a total of 44 (41.9%) of patients were male. Among the included SCAD patients the most prevalent comorbidities were fibromuscular dysplasia (FMD) and hypertension with the prevalence of 36.4 and 21.9%, respectively. Preceding physical stress was more frequently reported in men than in women; 38 out of 44 (86.4%) men reported physical stress, while 36 out of 61 (59.1%) females reported physical stress (p value = 0.009). On the other hand, the opposite was true for emotional stress (men: 6 (13.6%)), women: 29 (47.6%), p value < 0.001). Coronary angiography was the main diagnostic tool. The most frequently involved artery was the left anterior descending (LAD) (62.9%). In our study, recurrence of SCAD due to either the progression of a previous lesion or new SCAD in another coronary location occurred more frequently in those treated conservatively, however the observed difference was not statistically significant (p value = 0.138)., Conclusion: While physical stress seems to precede SCAD in most cases, emotional stress is implicated in females more than males., (© 2024.

Background: Randomized controlled trials (RCTs) have demonstrated the efficacy and safety of P2Y12 inhibitor monotherapy following short-term dual antiplatelet therapy (DAPT) in patients undergoing percutaneous coronary intervention (PCI). However, no studies have compared P2Y12 inhibitor and aspirin monotherapy following short-term DAPT. We aimed to compare available strategies for DAPT duration and post-DAPT antiplatelet monotherapy following PCI., Methods: Seven DAPT strategies [ticagrelor or clopidogrel following 1-month DAPT, ticagrelor following 3-month DAPT, aspirin following 3-6 months of DAPT (reference strategy), aspirin or P2Y12 inhibitor following 6-18-months of DAPT, and DAPT for ≥18 months] were compared using a network meta-analysis. The primary efficacy outcome was defined as a composite of all-cause death, myocardial infarction, and stroke. The primary bleeding outcome was trial-defined major or minor bleeding., Results: Our analysis identified 25 eligible RCTs, including 89,371 patients who underwent PCI. Overall, none of the strategies negatively affected the primary efficacy outcomes. For primary bleeding outcomes, ticagrelor following 3-month DAPT was associated with a reduced risk of primary bleeding outcomes (HR 0.73; 95 % CI 0.57-0.95). Clopidogrel following 1-month DAPT was also associated with a reduced risk of primary bleeding outcomes (HR 0.54; 95 % CI 0.34-0.85), however, the strategy was associated with an increased risk of myocardial infarction or stent thrombosis. Similar trends were observed among patients with acute coronary syndrome and high bleeding risk., Conclusions: Compared with aspirin monotherapy following short-term DAPT, ticagrelor following 3-month DAPT was associated with a reduced risk of primary bleeding outcomes without increasing any ischemic outcomes., Competing Interests: Declaration of competing interest Dr Kohsaka has received investigator-initiated grant funding from Novartis and personal fees from Bristol-Myers Squibb, Pfizer, and Bayer.

Background: Coronary artery calcium (CAC), thoracic aorta calcification (TAC), non-alcoholic fatty liver disease (NAFLD), and epicardial adipose tissue (EAT) are associated with atherosclerotic cardiovascular disease (ASCVD) and heart failure (HF)., Objectives: We aimed to determine whether these cardiometabolic and atherosclerotic risk factors identified by non-contrast chest computed tomography (CT) are associated with HF hospitalizations in patients with LDL-C≥ 190 mg/dL., Methods: We conducted a retrospective cohort analysis of patients with LDL-C ≥190 mg/dL, aged ≥40 years without established ASCVD or HF, who had a non-contrast chest CT within 3 years of LDL-C measurement. Ordinal CAC, ordinal TAC, EAT, and NAFLD were measured. Kaplan-Meier curves and multivariable Cox regression models were built to ascertain the association with HF hospitalization., Results: We included 762 patients with median age 60 (53-68) years, 68% (n=520) female, and median LDL-C level of 203 (194-216) mg/dL. Patients were followed for 4.7 (interquartile range 2.75-6.16) years, and 107 (14%) had a HF hospitalization. Overall, 355 (47%) patients had CAC=0, 210 (28%) had TAC=0, 116 (15%) had NAFLD, and median EAT was 79 mL (49-114). Moderate-Severe CAC (log-rank p<0.001) and TAC (log-rank p=0.006) groups were associated with increased HF hospitalizations. This association persisted when considering myocardial infarction (MI) as a competing risk. NAFLD and EAT volume were not associated with HF., Conclusions: In patients without established ASCVD and LDL-C≥190 mg/dL, CAC was independently associated with increased HF hospitalizations while TAC, NAFLD, and EAT were not., (Copyright © 2024.

Objectives: The long-term impact of permanent pacemaker (PPM) implantation on survival after cardiac surgery remains ill defined. We aimed to investigate the effect of PPM on survival and explore factors driving outcomes using meta-regression according to the type of surgery., Methods: MEDLINE, EMBASE, and the Cochrane Library Central Register of Controlled Trials were searched through October 2023 to identify studies reporting the long-term outcomes of PPM implantation. The primary outcome was all-cause mortality during follow-up. The secondary outcome was heart failure rehospitalization. The subgroup analysis and meta-regression analysis were performed according to the type of surgery., Results: A total of 28 studies met the inclusion criteria. 183,555 patients (n = 6298; PPM, n = 177,257; no PPM) were analyzed for all-cause mortality, with a weighted median follow-up of 79.7 months. PPM implantation was associated with increased risks of all-cause mortality during follow-up (hazard ratio, 1.22; confidence interval, 1.08-1.38, P < .01) and heart failure rehospitalization (hazard ratio, 1.24; confidence interval, 1.01-1.52, P = .04). Meta-regression demonstrated the adverse impact of PPM was less prominent in patients undergoing mitral or tricuspid valve surgery, whereas studies with a greater proportion with aortic valve replacement were associated with worse outcomes. Similarly, a greater proportion with atrioventricular block as an indication of PPM was associated with worse survival., Conclusions: PPM implantation after cardiac surgery is associated with a greater risk of long-term all-cause mortality and heart failure rehospitalization. This impact is more prominent in patients undergoing aortic valve surgery or atrioventricular block as an indication than those undergoing mitral or tricuspid valve surgery., Competing Interests: Conflict of Interest Statement Dr Kaneko has received consulting fees from Edwards Lifesciences, Medtronic, 4C Medical, CardioMech, and Cook Medical and has been a speaker for Abbott and Baylis.

Objective: This meta-analysis aimed to evaluate outcomes of transcatheter aortic valve replacement (TAVR) with percutaneous coronary intervention (PCI) versus surgical aortic valve replacement (SAVR) with coronary artery bypass grafting (CABG)., Methods: The MEDLINE, EMBASE, and Cochrane Library databases were searched through November 2021 to identify studies comparing TAVR + PCI and SAVR + CABG for severe aortic stenosis with concurrent coronary artery disease. Outcomes of interest were all-cause mortality, repeat coronary intervention, rehospitalization, myocardial infarction, and stroke during follow-up, and 30-day periprocedural outcomes., Results: Two randomized controlled trials and 6 observational studies including a total of 104,220 patients (TAVR + PCI, n = 5004; SAVR + CABG, n = 99,216) were included. The weighted mean follow-up period was 30.2 months. TAVR + PCI was associated with greater all-cause mortality and coronary reintervention during follow-up period (hazard ratio, 1.35; 95% confidence interval [CI], 1.11-1.65; P = .003, hazard ratio, 4.14; 95% CI, 1.74-9.86; P = .001, respectively), 30-day permanent pacemaker implantation rate (odds ratio [OR], 3.79; 95% CI, 1.61-8.95; P = .002), and periprocedural vascular complications (OR, 6.97; 95% CI, 1.85-26.30; P = .004). In contrast, TAVR + PCI was associated with a lower rate of 30-day acute kidney injury (OR, 0.32; 95% CI, 0.20-0.50; P = .0001). Rehospitalization, myocardial infarction, stroke during follow-up, and other periprocedural outcomes including 30-day mortality were similar in both groups., Conclusions: In patients with severe aortic stenosis and coronary artery disease, TAVR + PCI was associated with greater all-cause mortality at follow-up compared with SAVR + CABG. Heart Team approach to assess TAVR candidacy remains imperative., (Copyright © 2022 The American Association for Thoracic Surgery. Published by Elsevier Inc. All rights reserved.)

Background/purpose: It is unclear whether coronary physiology or coronary angiography (CA)-guided strategy is the more preferable approach for deferring percutaneous coronary intervention (PCI). We sought to evaluate the clinical efficacy of various PCI strategies through a network meta-analysis of randomized controlled trials (RCTs)., Methods/materials: We searched multiple databases for RCTs investigating the impact of the following strategies for the purpose of determining whether or not to defer PCI: fractional flow reserve, instantaneous wave-free ratio, quantitative flow ratio (QFR), and CA. We conducted a network meta-analysis for trial-defined major adverse cardiovascular events (MACE), all-cause death, cardiovascular death, myocardial infarction (MI), target lesion revascularization (TLR), and stent thrombosis. We performed a subgroup analysis for those with acute coronary syndrome (ACS)., Results: Our search identified 12 eligible RCTs including a total of 13,177 patients. QFR-guided PCI was associated with reduced MACE, MI, and TLR compared with CA-guided PCI (relative risk (RR) 0.68; 95 % confidence interval (CI] [0.49 to 0.94], RR 0.58; 95 % CI [0.36 to 0.96], and RR 0.58; 95 % CI [0.38 to 0.91], respectively). There were no significant differences in any pairs for all-cause death, cardiovascular death, or stent thrombosis. QFR was ranked the best in most outcomes. In the subgroup analysis of the ACS cohort, there were no significant differences in MACE between any comparisons., Conclusions: QFR was associated with reduced MACE, MI, and TLR compared with CA, and ranked the best in most outcomes.

Objective: Intravascular ultrasound (IVUS) is an important adjunctive tool for patients with lower extremity peripheral arterial disease (PAD) undergoing endovascular therapy (EVT). The evidence regarding the advantages of IVUS use is evolving, and recent studies have reported conflicting results. We aimed to perform a meta-analysis to evaluate the efficacy of IVUS during angiography-guided EVT for patients with PAD., Methods: MEDLINE and EMBASE were searched through April 2023 to identify studies that investigated the outcomes of IVUS with angiography-guided EVT vs angiography-alone-guided EVT. The primary outcome was restenosis/occlusion rate; secondary outcomes were target lesion revascularization, major amputation, and mortality., Results: One randomized controlled trial and 14 observational studies, largely of moderate quality, were included, yielding a total of 708,808 patients with 709,189 lesions that were treated with IVUS-guided EVT (n = 101,405) vs angiography-alone (n = 607,784). Compared with angiography alone, IVUS-guided EVT was associated with a non-significant trend towards decreased restenosis/occlusion (relative risk [RR], 0.74; 95% confidence interval [CI], 0.54-1.00; I 2  = 60%). Although the risk of target lesion revascularization and mortality were comparable (RR, 0.85; 95% CI, 0.65-1.10; I 2  = 70%; RR, 1.01; 95% CI, 0.79-1.28; I 2  = 43%, respectively), the use of IVUS was also associated with significantly lower risk of major amputation (RR, 0.74; 95% CI, 0.67-0.82; I 2  = 47%). Subgroup analysis focusing on femoropopliteal disease demonstrated significantly higher patency (RR, 0.72; 95% CI, 0.52-0.98; I 2  = 73%). However, superiority with major amputation was not observed., Conclusions: IVUS-guided EVT for PAD may possibly be associated with a lower major amputation rate compared with angiography alone-guided EVT, although the difference in patency remained an insignificant trend in favor of IVUS-guided EVT. Adjunctive use of IVUS during EVT may be beneficial, and further prospective studies are warranted to delineate this relationship and the applicability of this technology in routine practice., Competing Interests: Disclosures T.N. is a consultant of Boston Scientific, COOK Medical, Cordis, Kaneka Medix, NIPRO Tokai Medical Products, and OrbusNeich; and received an honorarium from Boston Scientific and TERUMO Corporation.

Introduction: Older adults with cancer who are being considered for cancer surgery are heterogenous, with variation in their physical, mental, and social baselines and risk of postoperative complications. Due in part to the complex nature of this population, the optimal preoperative evaluation method is not clearly defined. In this study we investigated whether geriatric-8 (G8), a screening tool for older patients with cancer that determines the need for a full geriatric assessment, is suitable for assessing the risk of postoperative complications in this population being considered for surgery., Materials and Methods: Studies that enrolled older patients undergoing cancer surgery and compared prevalence of postoperative complications in G8 "high" (≥15) patients and G8 "low" (<15) patients were identified using PubMed and EMBASE. A meta-analysis was conducted to calculate the risk ratio of postoperative complication rate. Postoperative mortality was systematically reviewed., Results: Eleven studies published between 2017 and 2022 were included in our analysis with a total of 2,691 older patients who underwent various types of cancer surgery and were characterized by their G8 scores: 1,255 G8 high (≥15) patients and 1,436 G8 low (<15) patients. G8 low patients had a significantly higher prevalence of postoperative complications than G8 high patients (risk ratio [95% confidence interval]: 1.56 [1.18-2.07], p = 0.002, I 2  = 79%)., Discussion: G8 can be an effective and efficient preoperative tool to assess risk of postoperative complications in older adults undergoing cancer surgery and identify potential need for further evaluation of an individual's risk with a comprehensive geriatric assessment., Competing Interests: Declaration of Competing Interest The authors declare no conflict of interest., (Copyright © 2023 Elsevier Ltd.

Background: There is no consensus regarding the strategies for repairing acute type A aortic dissection (ATAAD) in patients with bicuspid aortic valve (BAV). This meta-analysis aimed to compare the treatment strategies and outcomes of ATAAD repair between patients with BAV and those with tricuspid aortic valve (TAV)., Methods: A systematic review of databases were performed from inception through March 2023. The primary outcome of interest was all-cause mortality, with a minimum follow-up of 1 year. The secondary outcomes of interest included ratios of performed procedures and rate of distal aortic reoperation. Data were extracted, and pooled analysis was performed using a random-effects model., Results: Eight observational studies including a total of 3701 patients (BAV, n = 349; TAV, n = 3352) were selected for a meta-analysis. Concerning proximal aortic procedures, BAV patients exhibited a higher incidence of necessary root replacement (odds ratio [OR], 6.53; 95% confidence interval [CI], 3.84 to 11.09; P  < .01). Regarding distal aortic procedures, extended arch replacement was performed less frequently in BAV patients (OR, 0.69; 95% CI, 0.49 to 0.99; P  = .04), whereas hemiarch procedure rates were comparable in the 2 groups. All-cause mortality was lower in the BAV group (hazard ratio, 0.68; 95% CI, 0.50 to 0.92; P  = .01). Distal aortic reoperation rates were comparable in the 2 groups., Conclusions: This study highlights distinct procedural patterns in ATAAD patients with BAV and TAV. Despite differing baseline characteristics, BAV patients exhibited superior survival compared to TAV patients, with comparable distal aortic reoperation rates. These findings may be useful for decision making regarding limited versus extended aortic arch repair., Competing Interests: Dr Fukuhara serves as a consultant for Terumo Aortic, Artivion, Medtronic, and Edwards Lifesciences.

The 2018 heart allocation system has significantly influenced heart transplantation and left ventricular assist device (LVAD) utilization. Our study aims to investigate age-related outcomes following LVAD implantation in the post-allocation era. Using the National Inpatient Sample, we analyzed data from 7375 patients who underwent LVAD implantation between 2019 and 2020. The primary endpoint was in-hospital mortality following LVAD implantation, stratified by age categories. The age groups were 18-49, 50-59, 60-69, and over 70. These represented 26%, 26%, 31%, and 17% of patients, respectively. Patients aged 60-69 and those over 70 exhibited higher in-hospital mortality rates of 12% and 17%, respectively, compared to younger age groups (7% for 18-49 and 6% for 50-59). The age groups 60-69 and over 70 were independent predictors of mortality, with adjusted odds ratios of 1.99 ( p = 0.02; 95% confidence interval [CI], 1.12-3.57) and 2.88 ( p = 0.002; 95% CI, 1.45-5.71), respectively. Additionally, a higher Charlson Comorbidity Index was associated with increased in-hospital mortality risk (adjusted odds ratio 1.39; p = 0.02; 95% CI, 1.05-1.84). Additionally, patients above 70 experienced a statistically shorter length of stay. Nonhome discharge was found to be significantly high across all age categories. However, the difference in hospitalization cost was not statistically significant across the age groups. Our study highlights that patients aged 60 and above face an increased risk of in-hospital mortality following LVAD implantation in the post-allocation era. This study sheds light on age-related outcomes and emphasizes the importance of considering age in LVAD patient selection and management strategies.

Background: To investigate the individual profile of each SGLT2 (sodium-glucose cotransoporter-2) inhibitor in patients with different backgrounds., Methods and Results: This study included 21 placebo-controlled randomized controlled trials with a total of 96 196 participants, investigating empagliflozin, ertugliflozin, dapagliflozin, canagliflozin, and sotagliflozin. The primary efficacy end point was the composite of cardiovascular death and hospitalizations for heart failure. The secondary efficacy end points were all-cause death, cardiovascular death, hospitalizations for heart failure, kidney disease progression, and acute kidney injury. We conducted subgroup analyses based on the underlying comorbidities, including diabetes and chronic kidney disease. Safety end points were also assessed among SGLT2 inhibitors in the overall cohort. In the overall cohort, there were no significant differences in the primary efficacy outcome among the SGLT2 inhibitors, while empagliflozin (hazard ratio [HR], 0.70 [95% CI, 0.53-0.92]) and dapagliflozin (HR, 0.73 [95% CI, 0.56-0.96]) were associated with lower risk of acute kidney injury than sotagliflozin. The presence or absence of diabetes did not alter the results. In patients with chronic kidney disease, there were no differences in the efficacy outcomes among SGLT2 inhibitors, while in patients without chronic kidney disease, empagliflozin was associated with lower risk of the primary outcome compared with ertugliflozin (HR, 0.77 [95% CI, 0.60-0.98]). For safety outcomes, no significant differences were observed in amputation, urinary tract infection, genital infection, hypoglycemia, and diabetic ketoacidosis., Conclusions: The differences in reducing cardiovascular and kidney outcomes as well as safety profiles across SGLT2 inhibitors were not consistently significant, although empagliflozin might be preferred in patients without chronic kidney disease. Further investigations are needed to better understand the mechanism and clinical effectiveness of each SGLT2 inhibitor in certain populations.

Background: Tools for mortality prediction in patients with the severe hypercholesterolemia phenotype (low-density lipoprotein cholesterol ≥190 mg/dL) are limited and restricted to specific racial and ethnic cohorts. We sought to evaluate the predictors of long-term mortality in a large racially and ethnically diverse US patient cohort with low-density lipoprotein cholesterol ≥190 mg/dL., Methods: We conducted a retrospective analysis of all patients with a low-density lipoprotein cholesterol ≥190 mg/dL seeking care at Montefiore from 2010 through 2020. Patients <18 years of age or with previous malignancy were excluded. The primary end point was all-cause mortality. Analyses were stratified by age, sex, and race and ethnicity. Patients were stratified by primary and secondary prevention. Cox regression analyses were used to adjust for demographic, clinical, and treatment variables., Results: A total of 18 740 patients were included (37% non-Hispanic Black, 30% Hispanic, 12% non-Hispanic White, and 2% non-Hispanic Asian patients). The mean age was 53.9 years, and median follow-up was 5.2 years. Both high-density lipoprotein cholesterol and body mass index extremes were associated with higher mortality in univariate analyses. In adjusted models, higher low-density lipoprotein cholesterol and triglyceride levels were associated with an increased 9-year mortality risk (adjusted hazard ratio [HR], 1.08 [95% CI, 1.05-1.11] and 1.04 [95% CI, 1.02-1.06] per 20-mg/dL increase, respectively). Clinical factors associated with higher mortality included male sex (adjusted HR, 1.31 [95% CI, 1.08-1.58]), older age (adjusted HR, 1.19 per 5-year increase [95% CI, 1.15-1.23]), hypertension (adjusted HR, 2.01 [95% CI, 1.57-2.57]), chronic kidney disease (adjusted HR, 1.68 [95% CI, 1.36-2.09]), diabetes (adjusted HR, 1.79 [95% CI, 1.50-2.15]), heart failure (adjusted HR, 1.51 [95% CI, 1.16-1.95]), myocardial infarction (adjusted HR, 1.41 [95% CI, 1.05-1.90]), and body mass index <20 kg/m 2 (adjusted HR, 3.36 [95% CI, 2.29-4.93]). A significant survival benefit was conferred by lipid-lowering therapy (adjusted HR, 0.57 [95% CI, 0.42-0.77]). In the primary prevention group, high-density lipoprotein cholesterol <40 mg/dL was independently associated with higher mortality (adjusted HR, 1.49 [95% CI, 1.06-2.09]). Temporal trend analyses showed a reduction in statin use over time ( P <0.001). In the most recent time period (2019-2020), 56% of patients on primary prevention and 85% of those on secondary prevention were on statin therapy., Conclusions: In a large, diverse cohort of US patients with the severe hypercholesterolemia phenotype, we identified several patient characteristics associated with increased 9-year all-cause mortality and observed a decrease in statin use over time, in particular for primary prevention. Our results support efforts geared toward early recognition and consistent treatment for patients with severe hypercholesterolemia., Competing Interests: Disclosures Dr Slipczuk has received consulting honoraria from Philips and Amgen for lectures, participated in an advisory board meeting from BMS, and received grant support from Amgen and Philips (institutional).

Hybrid coronary revascularization (HCR) is an alternative option to conventional coronary artery bypass grafting (CABG), but the long-term outcomes of HCR versus CABG remain unclear. We aimed to analyze the long-term outcomes after HCR and CABG for patients with multivessel coronary artery disease using meta-analysis. A systemic literature search of PubMed and EMBASE was performed from inception to March 2023. Studies reporting Kaplan-Meier curves with follow-up ≥1 year were included. The primary outcome was all-cause mortality, and the secondary outcomes were major adverse cardiac and cerebrovascular events (MACCEs) and repeat revascularization. In total, 13 studies (1 randomized controlled trial and 12 propensity-score matched observational studies) were analyzed. The mean follow-up period was 5.1 ± 3.1 years. HCR was associated with similar overall mortality (hazard ratio [HR] 1.09, 95% confidence interval [CI] 0.87 to 1.36), significantly higher incidence of MACCEs (HR 1.49, 95% CI 1.07 to 2.06), and repeat revascularization (HR 2.01, 95% CI 1.53 to 2.64) compared with CABG. In phase-specific analysis, the mortality rate was similar, and the incidence of repeat revascularization was higher in HCR regardless of phases. The incidence of MACCEs was higher in HCR during the mid-term phase (1 to 5 years), but it was similar during the long-term phase (long-term: ≥5 years). In conclusion, despite the higher incidence of MACCEs and repeat revascularization compared with CABG, HCR offered a similar long-term survival. Even longer-term follow-up and randomized controlled trials with a large population are warranted to investigate the role of HCR for multivessel coronary artery disease., Competing Interests: Declaration of competing interest Dr. Fukuhara reports a relation with Terumo Aortic that includes consulting or advisory.

Background: There is currently little evidence for transcatheter edge-to-edge mitral valve repair (TEER) for mitral regurgitation (MR) in patients with cardiogenic shock (CS). Therefore, this study investigated the characteristics and outcomes of CS patients who underwent TEER for MR., Methods: PubMed, EMBASE were searched in July 2023. Case series and observational studies reporting clinical characteristics and outcomes in CS patients with MR who underwent TEER were included. We performed a one-group meta-analysis using a random effects model., Results: A total of 4060 patients from 7 case series and 5 observational studies were included. The mean age was 68.2 (95% confidence interval [CI]: 64.1-72.2) years, and 41.4% of patients (95% CI: 39.1%-43.7%) were female. Pre-TEER, severe MR was present in 85.3% (95% CI: 76.1%-91.3%) of patients. Mean left ventricular ejection fraction was 36.7% (95% CI: 29.2%-44.2%), and 54.6% (95% CI: 36.9%-71.2%) of patients received mechanical circulatory support. The severity of MR post-TEER was less than 2+ in 88% (95% CI: 87%-89%) of patients. In-hospital mortality was 11% (95% CI: 10%-13%), whereas 30-day and 1-year mortality rates were 15% (95% CI: 13%-16%), and 36% (95% CI: 21%-54%), respectively., Conclusions: This systematic review and meta-analysis assessed the clinical characteristics and outcomes of TEER in CS patients with MR. TEER for MR in patients with CS has been successful in reducing MR in most of the patients, but with a high mortality rate. Randomized controlled trials of TEER for MR and CS are needed., (© 2023 Wiley Periodicals LLC.)

Background: Evidence is limited regarding patient outcomes comparing redo surgical mitral valve replacement (redo SMVR) vs transcatheter mitral valve replacement (TMVR) for failed prostheses., Objectives: The goal of this study was to compare the outcomes of redo SMVR vs TMVR in patients with failed prostheses, as well as evaluate the association between case volume and outcomes., Methods: Medicare beneficiaries aged ≥65 years who underwent redo SMVR or TMVR for failed mitral prostheses between 2016 and 2020 were included. The primary endpoint was mid-term (up to 3 years) major adverse cardiovascular events (MACE), including all-cause death, heart failure rehospitalization, stroke, or reintervention. Propensity score-matched analysis was used., Results: A total of 4,293 patients were included (redo SMVR: 64%; TMVR: 36%). TMVR recipients were older, with a higher comorbidity burden. In matched cohort (n = 1,317 in each group), mid-term risk of MACE was similar (adjusted HR: 0.92; 95% CI: 0.80-1.04; P = 0.2). However, landmark analysis revealed a lower risk of MACE with TMVR in the first 6 months (adjusted HR: 0.75; 95% CI: 0.63-0.88; P < 0.001) albeit with a higher risk beyond 6 months (adjusted HR: 1.28; 95% CI: 1.04-1.58; P = 0.02). Increasing procedural volume was associated with decreased risk of mid-term MACE after redo SMVR (P = 0.001) but not after TMVR (P = 0.3)., Conclusions: In this large cohort of Medicare beneficiaries with failed mitral prostheses, outcomes were similar between redo SMVR and TMVR at 3 years, with TMVR showing a lower initial risk but a higher risk of MACE after 6 months.

Background: Previous literature suggests that both SARS-CoV-2 infection and COVID-19 mRNA vaccine are associated with myocarditis, in which the incidence is higher in the infection group. COVID-19 mRNA vaccine-related myocarditis is noted to have a more benign course. Despite these findings, there is a need for a larger population systematic review that compares the outcomes to pre-pandemic acute myocarditis to better understand the extent of the current post-COVID state., Methods: We performed a literature search with PubMed and EMBASE and identified studies investigating COVID-19 and its vaccinated population, and the population prior to the pandemic (control group) who had myocarditis. We performed a one-group meta-analysis of the incidence, baseline demographics, and outcomes of myocarditis for each group., Results: The incidence in the SARS-CoV-2 infection group was 2.76 per thousand (95% CI, 0.85-8.92), 19.7 per million (95% CI, 12.3-31.6) in the vaccine group, and 0.861 per million (95% CI, 0.04-16.7) in the control group. The majority of patients were male, with the highest proportion in the vaccine group. The mean age was the youngest in the vaccine group (24.8, 95% CI, 19.1-30.6). The vaccine group had the lowest mortality (2.0%, 95% CI, 1.3-2.7) followed by the control and the SARS-CoV-2 infection group. The vaccine group had the lowest proportion of immunoglobulin and glucocorticoid use, mechanical circulatory support, and cardiogenic shock., Conclusion: Our study showed favorable outcomes of myocarditis in patients with COVID-19 mRNA vaccination, despite a higher incidence than pre-COVID controls. Further studies with standardized myocarditis diagnostic criteria assessing long-term outcomes are necessary., Competing Interests: Declaration of Competing Interest None., (Copyright © 2023 Elsevier B.V.

It remains unclear which percutaneous coronary intervention (PCI) strategy is the most preferable in patients with small-vessel coronary artery disease (CAD). We sought to evaluate the clinical efficacy of various PCI strategies for patients with small-vessel CAD through a network meta-analysis of randomized controlled trials (RCTs). We searched multiple databases for RCTs investigating the efficacy of the following PCI strategies for small-vessel CAD (<3 mm in diameter): drug-coated balloons (DCB), early-generation paclitaxel-eluting stents and sirolimus-eluting stents (SES), newer-generation drug-eluting stents (DES), bare-metal stents (BMS), cutting balloon angioplasty, and balloon angioplasty (BA). The primary outcome was the trial-defined major adverse cardiovascular events (MACE), mostly defined as a composite of death, myocardial infarction, and revascularization. The secondary outcomes included each component of MACE and angiographic binary restenosis. We performed a sensitivity analysis for RCTs without BMS or first-generation DES. Our search identified 29 eligible RCTs, including 8,074 patients among the 8 PCI strategies. SES significantly reduced MACE compared with BA (hazard ratio 0.23, 95% confidence interval 0.10 to 0.54) with significant heterogeneity (I 2  = 55.9%), and the rankogram analysis showed that SES was the best. There were no significant differences between DCB and newer-generation DES in any clinical outcomes, which was consistent in the sensitivity analysis. BMS and BA were ranked as the worst 2 for most clinical outcomes. In conclusion, SES was ranked as the best for reducing MACE. There were no significant differences in clinical outcomes between DCB and newer-generation DES. BMS and BA were regarded as the worst strategies for small-vessel CAD., Competing Interests: Declaration of Competing Interest The authors have no competing interests to declare., (Copyright © 2023 Elsevier Inc.

Background: Computed tomography aortic valve calcium (AVC) score has accepted value for diagnosing and predicting outcomes in aortic stenosis (AS). Multi-energy CT (MECT) allows virtual non-contrast (VNC) reconstructions from contrast scans. We aim to compare the VNC-AVC score to the true non-contrast (TNC)-AVC score for assessing AS severity., Methods: We prospectively included patients undergoing a MECT for transcatheter aortic valve replacement (TAVR) planning. TNC-AVC was acquired before contrast, and VNC-AVC was derived from a retrospectively gated contrast-enhanced scan. The Agatston scoring method was used for quantification, and linear regression analysis to derive adjusted-VNC values., Results: Among 109 patients (55% female) included, 43% had concordant severe and 14% concordant moderate AS. TNC scan median dose-length product was 116 ​mGy∗cm. The median TNC-AVC was 2,107 AU (1,093-3,372), while VNC-AVC was 1,835 AU (1293-2,972) after applying the coefficient (1.46) and constant (743) terms. A strong correlation was demonstrated between methods (r ​= ​0.93; p ​< ​0.001). Using accepted thresholds (>1,300 AU for women and >2,000 AU for men), 65% (n ​= ​71) of patients had severe AS by TNC-AVC and 67% (n ​= ​73) by adjusted-VNC-AVC. After estimating thresholds for adjusted-VNC (>1,564 AU for women and >2,375 AU for men), 56% (n ​= ​61) had severe AS, demonstrating substantial agreement with TNC-AVC (κ ​= ​0.77)., Conclusions: MECT-derived VNC-AVC showed a strong correlation with TNC-AVC. After adjustment, VNC-AVC demonstrated substantial agreement with TNC-AVC, potentially eliminating the requirement for an additional scan and enabling reductions in both radiation exposure and acquisition time., Competing Interests: Declaration of competing interest L.S. has received consulting honorarium from Amgen, BMS and Philips; and grant support from Amgen and Philips.

A 53-year-old man with an abnormal routine physical examination was referred to our hospital. Colonoscopy showed a 5-mm submucosal tumor that was 7cm proximal to the ileocecal valve. It was identified as a neuroendocrine tumor (NET) on biopsy. Preoperatively, we conducted a double balloon endoscopy to examine the entire small intestine. Another 7-mm submucosal tumor was found on the ileocecal valve, which was missed during the first colonoscopy. A final diagnosis of multiple ileal NETs (<10mm in diameter) was made, and the patient underwent ileocecal resection with lymphadenectomy. Histopathological evaluation of the surgical specimen verified the diagnosis of NET Grade 1 with submucosal invasion. Metastasis to lymph node #202 was also detected. He remained relapse-free for 5 years and 5 months after the operation. In conclusion, this was a case of multiple ileal NETs (<10mm in diameter) with lymph node metastasis that could not be detected preoperatively on contrast-enhanced computed tomography. This case highlights the significance of detailed endoscopic observation of the terminal ileum.

Background: In patients undergoing percutaneous coronary intervention (PCI), it remains unclear whether intravascular imaging guidance or functional guidance is the best strategy to optimize outcomes and if the results are different in patients with vs without acute coronary syndromes (ACS)., Objectives: The purpose of this study was to evaluate clinical outcomes with imaging-guided PCI or functionally guided PCI when compared with conventional angiography-guided PCI., Methods: We searched PUBMED and EMBASE for randomized controlled trials investigating outcomes with intravascular imaging-guided, functionally guided, or angiography-guided PCI. The primary outcome from this network meta-analysis was trial-defined major adverse cardiovascular event (MACE)-a composite of cardiovascular death, myocardial infarction (MI), and target lesion revascularization (TLR). PCI strategies were ranked (best to worst) using P scores., Results: Our search identified 32 eligible randomized controlled trials and included a total of 22,684 patients. Compared with angiography-guided PCI, intravascular imaging-guided PCI was associated with reduced risk of MACE (relative risk [RR]: 0.72; 95% CI: 0.62-0.82), cardiovascular death (RR: 0.56; 95% CI: 0.42-0.75), MI (RR: 0.81; 95% CI: 0.66-0.99), stent thrombosis (RR: 0.48; 95% CI: 0.31-0.73), and TLR (RR: 0.75; 95% CI: 0.57-0.99). Similarly, when compared with angiography-guided PCI, functionally guided PCI was associated with reduced risk of MACE and MI. Intravascular imaging-guided PCI ranked first for the outcomes of MACE, cardiovascular death, stent thrombosis, and TLR. The results were consistent in the ACS and non-ACS cohorts., Conclusions: Angiography-guided PCI had consistently worse outcomes compared with intravascular imaging-guided and functionally guided PCI.

Background: Transcatheter aortic valve replacement (TAVR) is as an alternative treatment to surgical AVR, but the long-term outcomes of TAVR remain unclear., Aims: This study aimed to analyze long-term outcomes following TAVR using meta-analysis., Methods: A literature search was performed with MEDLINE, EMBASE, Cochrane Library, Web of Science, and Google Scholar through November 2022; studies reporting clinical outcomes of TAVR with follow-up periods of ≥8 years were included. The outcomes of interest were overall survival and/or freedom from structural valve deterioration (SVD). Surgical risk was assessed with the Society of Thoracic Surgeons (STS) predicted risk of mortality (PROM) score. A subgroup analysis was conducted for intermediate-/high-surgical risk patients only., Results: Eleven studies including 5458 patients were identified and analyzed. The mean age was 82.0 ± 6.5 years, and mean STS PROM score ranged from 2.9 to 10.6%. Survival rate at 5 and 10 years was 47.7% ± 1.4% and 12.1 ± 2.0%. Five studies including 1509 patients were analyzed for SVD. Freedom from SVD at 5 and 8 years was 95.5 ± 0.7% and 85.1 ± 3.1%. Similar results for survival and SVD were noted in the subgroup analysis of intermediate-/high-risk patients., Conclusions: Following TAVR, approximately 88% of patients died within 10 years, whereas 85% were free from SVD at 8 years. These date suggest that baseline patient demographic have the greatest impact on survival, and SVD does not seem to have a prognostic impact in this population. Further investigations on longer-term outcomes of younger and lower-risk patients are warranted., (© 2023 Wiley Periodicals LLC.)

We performed a network meta-analysis of 11 published randomized clinical trials examining the use of temporary mechanical circulatory support (MCS) devices in adults with acute myocardial infarction cardiogenic shock, including 1,053 total patients with an observed in-hospital or 30-day mortality of 40.4%. None of the temporary MCS devices was associated with lower in-hospital or 30-day mortality compared with initial medical therapy or any other MCS device, either individually or in combination. These data do not support the routine use of temporary MCS devices for the purpose of reducing short-term mortality in unselected patients with acute myocardial infarction cardiogenic shock., Competing Interests: Disclosures Dr Bangalore reports advisory board/honoraria from Abbott Vascular, Boston Scientific, Biotronik, Amgen, Pfizer, REATA, INARI, TRUVIC, Merck.

Background: United Network for Organ Sharing (UNOS) allocation criteria changed in 2018 to accommodate the increased prevalence of ventricular assist device use as a bridge to heart transplant, which consequently prioritized sicker patients. We aimed to assess the impact of this new allocation policy on the length of stay following heart transplantation. Secondary outcomes include other risk factors for prolonged hospitalization and its effect on mortality and postoperative complications., Methods: The UNOS Registry was queried to identify patients who underwent isolated heart transplants in the United States between 2001 and 2023. Patients were divided into quartiles according to their respective length of stay., Results: A total of 57 020 patients were included, 15 357 of which were allocated with the new system. The median hospital length of stay was 15 days (mean 22.7 days). Length of stay was longer in the new allocation era (25 ± 30 vs. 22 ± 27 days, p < .001). The longer length of stay was associated with increased 5-year mortality in the new allocation system (aHR: 1.18; 95% CI: 1.15, 1.20; p-value: < .001)., Conclusion: Longer hospital stays and associated observed increased risk for mortality in the era after the allocation criteria change reflect the rationale of this shift which was to prioritize heart transplants for sicker patients. Further studies are needed to track the progress of surgical and perioperative management of these studies over time., (© 2023 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Long-term outcomes of iatrogenic coronary dissection and perforation in patients undergoing percutaneous coronary intervention (PCI) remains under-investigated. We analyzed 8,721 consecutive patients discharged after PCI between 2008 and 2019 from Keio Cardiovascular (KiCS) PCI multicenter prospective registry in the Tokyo metropolitan area. Significant coronary dissection was defined as persistent contrast medium extravasation or spiral or persistent filling defects with complete distal and impaired flow. The primary outcome was a composite of all-cause death, acute coronary syndrome, heart failure, bleeding, stroke requiring admission, and coronary artery bypass grafting two years after discharge. We used a multivariable Cox hazard regression model to assess the effects of these complications. Among the patients, 68 (0.78%) had significant coronary dissections, and 61 (0.70%) had coronary perforations at the index PCI. Patients with significant coronary dissection had higher rates of the primary endpoint and heart failure than those without (25.0% versus 14.3%, P = 0.02; 10.3% versus 4.2%, P = 0.03); there were no significant differences in the primary outcomes between the patients with and without coronary perforation (i.e., primary outcome: 8.2% versus 14.5%, P = 0.23) at the two-year follow-up. After adjustments, patients with coronary dissection had a significantly higher rate of the primary endpoint than those without (HR 1.70, 95% CI 1.02-2.84; P = 0.04), but there was no significant difference in the primary endpoint between the patients with and without coronary perforation (HR 0.51, 95% CI 0.21-1.23; P = 0.13). For patients undergoing PCI, significant coronary dissection was associated with poor long-term outcomes, including heart failure readmission., (© 2023. The Author(s).)

Aims: Transradial intervention (TRI) for percutaneous coronary intervention (PCI) is used to reduce periprocedural complications. However, its effectiveness and safety for patients on dialysis are not well established. We aimed to investigate the association of TRI with in-hospital complications in dialysis patients undergoing PCI., Methods and Results: We included 44 462 patients on dialysis who underwent PCI using Japanese nationwide PCI registry data (2019-21) regardless of acute or chronic coronary syndrome. Patients were categorized based on access site: TRI, transfemoral intervention (TFI). Periprocedural access site bleeding complication requiring transfusion was the primary outcome and in-hospital death, and other periprocedural complications were the secondary outcomes. Matched weighted analysis was performed for TRI and TFI. Here, 8267 (18.6%) underwent TRI, and 36 195 (81.4%) underwent TFI. Patients who received TRI were older and had lower rates of comorbidities than those who received TFI. Access site bleeding rate and in-hospital death were significantly lower in the TRI group (0.1% vs. 0.7%, P < 0.001; 1.8% vs. 3.2%, P < 0.001, respectively). After adjustment, TRI was associated with a lower risk of access site bleeding (odds ratio [OR] [95% confidence interval (CI)]: 0.19 [0.099-0.38]; P < 0.001) and in-hospital death (OR [95% CI]: 0.79 [0.65-0.96]; P = 0.02). Other periprocedural complications between TRI and TFI were not significantly different., Conclusion: In patients undergoing dialysis and PCI, TRI had a lower risk of access site bleeding and in-hospital death than TFI. This suggests that TRI may be safer for this patient population., (© The Author(s) 2023. Published by Oxford University Press on behalf of the European Society of Cardiology.)

Background Data on clinical outcomes after transcatheter aortic valve replacement (TAVR) in specific cancer types or the presence of metastatic disease remain sparse. This study aimed to investigate the impact of active cancer on short-term mortality, complications, and readmission rates after TAVR across different cancer types. Methods and Results The authors assessed the Nationwide Readmissions Database for TAVR cases from 2012 to 2019. Patients were stratified by specific cancer types. Primary outcome was in-hospital mortality. Secondary outcomes included bleeding requiring blood transfusion and readmissions at 30, 90, and 180 days after TAVR. Overall, 122 573 patients undergoing TAVR were included in the analysis, of whom 8013 (6.5%) had active cancer. After adjusting for potential confounders, the presence of active cancer was not associated with increased in-hospital mortality (adjusted odds ratio [aOR], 1.06 [95% CI, 0.89-1.27]; P =0.523). However, active cancer was associated with an increased risk of readmission at 30, 90, and 180 days after TAVR and increased risk of bleeding requiring transfusion at 30 days. Active colon and any type of metastatic cancer were individually associated with readmissions at 30, 90, and 180 days after TAVR. At 30 days after TAVR, colon (aOR, 2.51 [95% CI, 1.68-3.76]; P <0.001), prostate (aOR, 1.40 [95% CI, 1.05-1.86]; P =0.021), and any type of metastatic cancer (aOR, 1.65 [95% CI, 1.23-2.22]; P =0.001) were individually associated with an increased risk of bleeding requiring transfusion. Conclusions Patients with active cancer had similar in-hospital mortality after TAVR but higher risk of readmission and bleeding requiring transfusion, the latter depending on certain types of cancer.

Introduction: Life-long anticoagulation is the recommended management for chronic thromboembolic pulmonary hypertension (CTEPH). Evidence regarding the use of direct oral anticoagulants (DOAC) for CTEPH is yet to be established. We performed a systematic review and meta-analysis to clarify the outcomes of CTEPH in patients who used DOAC or vitamin K antagonists (VKA)., Methods: We reviewed literature in PubMed and EMBASE through March 2023. We included studies involving patients with CTEPH where DOAC and VKA were compared. We collected data including intervention history for CTEPH, bleeding events, recurrence of VTE (venous thromboembolism), and mortality. We performed a meta-analysis using the Mantel-Haenszel method with a fixed-effects model., Results: We included one randomized clinical trial and six observational studies, with a total of 2969 patients. Six studies investigated major bleeding outcomes, and seven investigated all bleeding outcomes. There were no differences in major bleeding (RR 0.59, 95 % CI [0.34-1.02], I 2  = 0 %) and all-bleeding (RR 0.87, 95 % CI [0.67-1.13], I 2  = 0 %). Based on the five studies we included, DOAC was associated with a lower risk of mortality (RR 0.54, 95 % CI: 0.37-0.79, I 2  = 5 %). However, a higher risk of recurrent pulmonary embolism (PE) was seen in three studies (RR 3.80, 95 % CI: [1.93-7.50], I 2  = 11 %). No significant differences were noted in terms of VTE., Conclusion: DOAC compared to VKA was associated with a significantly lower mortality and higher risk of recurrent PE. Since most of the included studies are observational, we must consider the existence of multiple biases and confounding factors., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

Young patients who underwent percutaneous coronary intervention (PCI) have shown worse long-term outcomes but remain inadequately investigated. We analyzed 1,186 consecutive young patients (aged ≤55 years) from the Keio Cardiovascular PCI registry who were successfully discharged after PCI (2008 to 2019) and compared them to 5,048 older patients (aged 55 to 75 years). The primary outcome was a composite of all-cause death, acute coronary syndrome, heart failure, bleeding, stroke requiring admission, and coronary artery bypass grafting within 2 years after discharge. In the young patients, the mean age was 48.4 ± 5.4 years, acute coronary syndrome cases accounted for 69.6%, and 92 (7.8%) were female. Body mass index; hemoglobin levels; and proportions of smoking, hyperlipidemia, and ST-elevation myocardial infarction were lower and dialysis or active cancer proportions were higher in young female patients than male patients. A higher number of young female than male patients reached the primary end point and all-cause death (15.2% vs 7.1%, p = 0.01; 4.3% vs 1.0%, p = 0.023), mainly because of noncardiac death (4.3% versus 0.5%, p = 0.001). After covariate adjustment, the primary end point rates were higher among young women than men (hazard ratio 2.00, 95% confidence interval 1.03 to 3.89, p = 0.042). Gender did not predict the primary end point among older patients (vs men; hazard ratio 0.84, 95% confidence interval 0.67 to 1.06, p = 0.14). In conclusion, young women showed worse outcomes during the 2-year post-PCI follow-up, but this gender difference was absent in patients aged 55 to 75 years., Competing Interests: Declaration of Competing Interest Dr. Kohsaka has received speaker fees from Bristol Myers Squibb and institutional research grant support from Novartis and AstraZeneca.

Background: Contemporary dual antiplatelet therapy (DAPT) strategies, such as short-term DAPT or de-escalation of DAPT, have emerged as attractive strategies to treat patients with acute coronary syndrome (ACS). However, it remains uncertain whether they are suitable for elderly patients., Methods: PubMed, Embase, and Cochrane CENTRAL databases were searched in September 2022. Randomized controlled trials (RCTs) investigating DAPT strategies, including standard (12 months), short-term, uniform de-escalation, and guided-selection strategies for elderly patients with ACS (age ≥ 65 years) were identified, and a network meta-analysis was conducted. The primary endpoint was the net clinical benefit outcome, a composite of major adverse cardiovascular events (MACEs: cardiovascular death, myocardial infarction, or stroke) and clinically relevant bleeding (equivalent to bleeding of at least type 2 according to the Bleeding Academic Research Consortium). The secondary outcomes were MACE and major bleeding., Results: Sixteen RCTs with a combined total of 47,911 patients were included. The uniform de-escalation strategy was associated with an improved net clinical benefit compared with DAPT using potent P2Y 12 inhibitors. The short-term DAPT strategy was associated with reduced risks of the primary outcome and major bleeding compared with DAPT using potent P2Y 12 inhibitors, however, it was ranked as the least effective strategy for MACE compared with other DAPT strategies., Conclusions: Uniform de-escalation and short-term DAPT strategies may be advantageous for elderly patients, but need to be tailored based on individual bleeding and ischemic risks. Further RCTs of contemporary DAPT strategies specifically designed for elderly patients are warranted to confirm the findings of the present study., (© 2023 Wiley Periodicals LLC.)

The optimal treatment strategy using pulmonary vasodilators in pulmonary arterial hypertension associated with CHD (PAH-CHD) remains controversial. We aimed to compare the efficacy and safety of pulmonary vasodilators in PAH-CHD. PubMed and EMBASE databases were searched through May 2022 and a network meta-analysis was conducted. The primary outcomes were mean difference of changes in 6-minute walk distance, NYHA functional class, and N-terminal pro-brain natriuretic peptide. The secondary outcomes included pulmonary vascular resistance, mean pulmonary arterial pressure, and resting oxygen saturation. We identified 14 studies, yielding 807 patients with PAH-CHD. Bosentan and sildenafil were associated with a significant increase in 6-minute walk distance from baseline compared with placebo (MD 48.92 m, 95% CI 0.32 to 97.55 and MD 59.70 m, 95% CI 0.88 to 118.53, respectively). Bosentan, sildenafil, and combination of bosentan and sildenafil were associated with significant improvement in NYHA functional class compared with placebo (MD -0.33, 95% CI -0.51 to -0.14, MD -0.58, 95% CI -0.75 to -0.22 and MD -0.62, 95% CI -0.92 to -0.31, respectively). Bosentan and sildenafil were also associated with significant improvements in secondary outcomes. These findings were largely confirmed in the subgroup analysis. Various adverse events were reported; however, serious adverse event rates were relatively low (4.8-8.7%), including right heart failure, acute kidney injury, respiratory failure, hypotension, and discontinuation of pulmonary vasodilators. In conclusion, bosentan and sildenafil were the most effective in improving prognostic risk factor such as 6-minute walk distance and NYHA class. Overall, pulmonary vasodilators were well tolerated in PAH-CHD.

Background: Although the use of intravascular ultrasound (IVUS) during percutaneous coronary intervention (PCI) has been shown to improve clinical outcomes, its utilization remains inconsistent. We aimed to assess the association between IVUS-guided PCI and long-term outcomes in Japan, where a high proportion of patients undergo IVUS., Methods: We analyzed 8721 consecutive patients in a multicenter PCI registry. The primary outcome was a composite of death, acute coronary syndrome, and heart failure requiring admission and coronary artery bypass grafting at 2 years after discharge. The secondary outcome was each component of the primary outcome. We used inverse probability-weighted analysis for adjustment. Subgroup analysis was conducted on patients with complex coronary anatomy (eg, those with bifurcation, chronic total occlusion, type C lesion, left main and those who underwent rotational atherectomy)., Results: Overall, 83.8% of patients underwent IVUS-guided PCI (mean age, 68.3 ± 11.3 years). After adjustments, the IVUS group had significantly lower rates of death and coronary bypass compared to no IVUS group (hazard ratio [HR], 0.73; 95% CI, 0.55-0.96; and HR, 0.62; 95% CI, 0.39-0.98) at 2-year follow-up, although the primary outcome showed only marginal differences (HR, 0.85; 95% CI, 0.71-1.01). In the subgroup analysis of complex coronary anatomy, the use of IVUS was significantly associated with a reduced risk of the primary outcome (HR, 0.72; 95% CI, 0.55-0.93) as well as death, coronary bypass, and heart failure., Conclusions: IVUS was frequently utilized in our registry and demonstrated potential benefit in reducing mortality and need for coronary bypass surgery, particularly in patients with complex coronary anatomy., (© 2023 The Author(s).)

Background: Various durations and de-escalation strategies of dual antiplatelet therapy (DAPT) after ST-elevation myocardial infarction (STEMI) or non-ST-elevation acute coronary syndromes (NSTE-ACS) have been tested in randomized controlled trials (RCT)s. However, evidence by specific ACS subtype is unknown., Methods: PubMed, EMBASE, and Cochrane CENTRAL were searched in February 2023. RCTs on DAPT strategies included STEMI or NSTE-ACS patients with standard DAPT (12 months) with clopidogrel or potent P2Y 12 inhibitors, short-term DAPT (≤6 months) followed by potent P2Y 12 inhibitors or aspirin, unguided de-escalation from potent P2Y 12 inhibitors to low-dose potent P2Y 12 inhibitors or clopidogrel at one month, and guided selection with genotype or platelet function tests were identified. The primary outcome was the net adverse clinical events (NACE) defined as a composite of major adverse cardiovascular events (MACE) and clinically relevant bleeding events., Results: Twenty RCTs with a combined total population of 24,745 STEMI and 37,891 NSTE-ACS patients were included. In STEMI patients, unguided de-escalation strategy was associated with a lower rate of NACE compared with standard DAPT using potent P2Y 12 inhibitors (HR:0.57; 95% CI:0.34-0.96) without increased risk of MACE. In NSTE-ACS patients, unguided de-escalation strategy was associated with a lower rate of NACE compared with the guided selection strategy (HR:0.65; 95% CI:0.47-0.90), standard DAPT using potent P2Y 12 inhibitors (HR:0.62; 95% CI:0.50-0.78) and standard DAPT using clopidogrel (HR:0.73; 95% CI:0.55-0.98) without increased risk of MACE., Conclusion: Unguided de-escalation strategy was associated with a reduced risk of NACE and may be the most effective DAPT strategy for STEMI and NSTE-ACS., Competing Interests: Declaration of Competing Interest Dr. Slipczuk has received consulting honoraria from Amgen, Regeneron and Phillips and a research grant from Amgen.

Background: The choice of an alternative access for transcatheter aortic valve replacement (TAVR) remains controversial when transfemoral (TF) access is not feasible., Methods: We conducted a network meta-analysis to compare the outcomes of TAVR via various peripheral vascular accesses. MEDLINE and EMBASE were searched through July 2022 to identify studies that investigated outcomes in patients who underwent TAVR via TF, trans-subclavian (Tsc), transcarotid (TC), or transcaval (Tcav) access. A network meta-analysis was conducted via random-effects model. Outcomes of interest were major or life-threatening bleeding, stroke, major vascular complication, and 30-day mortality., Results: No randomized trial was identified. Our analysis included 33 observational studies that enrolled a total of 43,455 patients who underwent TAVR via TF (n = 36,202), Tsc (n = 3869), TC (n = 3066), or Tcav (n = 318) access. The risk of major or life-threatening bleeding was higher via Tsc compared with TF [odds ratio (OR); 95 % confidence interval (CI) =1.51 (1.03-2.23), p = 0.034]. The risk of stroke was higher via Tsc compared with TF and Tcav [OR (95 % CI) =2.00 (1.14-3.52), p = 0.018, OR (95 % CI) =2.43 (1.03-5.74), p = 0.044, respectively]. The risk of major vascular complications was lower via TC compared with Tsc, and Tcav and higher with Tcav compared with TF and Tsc. 30-day mortality was higher via Tsc compared with TF. Tsc was associated with higher risk of major or life-threatening bleeding compared with TF, and higher risk of stroke compared to TF and Tcav. Tcav had the highest risk of major vascular complications., Conclusion: In patients who underwent TF, Tsc, TC, or Tcav TAVR, Tsc had a higher rate of stroke compared to TF and Tcav, and major or life-threatening bleeding compared to TF. The rate of major vascular complications in Tcav was the highest among the four approaches., Competing Interests: Declaration of competing interest Dr. Latib has served on advisory boards or as a consultant for Medtronic, Boston Scientific, Philips, Edwards Lifesciences, and Abbott., (Copyright © 2023 Elsevier Ltd.

Background: Transcatheter edge-to-edge repair (TEER) may have potential benefits in the treatment of atrial functional mitral regurgitation (AFMR), but robust evidence is currently lacking. We conducted a systematic review and meta-analysis to investigate the clinical outcomes of TEER for AFMR, including comparisons to ventricular functional MR (VFMR)., Methods: MEDLINE and EMBASE were searched through January 2023 to identify studies eligible for analysis. The primary outcome was postprocedural MR severity. Postprocedural New York Heart Association (NYHA) functional class classification and all-cause mortality were also evaluated. Outcomes were stratified into short term (postprocedure to 6 months) and long term (6 months to 2 years)., Results: A total of eight observational studies met the inclusion criteria, enrolling 539 AFMR and 3486 VFMR patients. Postprocedural MR grade ≤2 in the AFMR group was observed in 93.7% (454/491 patients; 95% confidence interval (CI), 91.1%-96.2%, I 2  = 24.3%) and 97.1% (89/93 patients; 95% CI, 92.9%-100%, I 2  = 26.4%) in short- and long-term follow-up, respectively. There was no difference in the rates of postprocedural MR grade ≤2 between AFMR and VFMR either in short-term (risk ratio [RR], 1.00 [95% CI, 0.95-1.06]; p = 0.90; I 2  = 53%) or long-term follow-up (RR, 1.08 [95% CI, 0.89-1.32]; p = 0.44; I 2  = 22%). Similarly, no difference was observed between AFMR and VFMR in the rates of postprocedural NYHA class ≤2 or all-cause mortality., Conclusion: TEER provides similar clinical outcomes for AFMR and VFMR. A high rate of MR grade ≤2 was observed in patients at both short- and long-term follow-ups. Further prospective studies with TEER versus medical therapy and/or rhythm control for AFMR are warranted., (© 2023 Wiley Periodicals LLC.)

Objective: Stroke is one of the devastating complications after coronary artery bypass graft (CABG). Underlying carotid artery atherosclerotic disease is reported to be an independent risk factor. The optimal treatment strategy for these patients remains under debate., Methods: We aimed to perform a network meta-analysis to evaluate the safety and efficacy of additional carotid interventions for patients with concomitant carotid artery atherosclerotic disease who require CABG by comparing perioperative adverse event rates. All articles through February 2022 were searched using MEDLINE and EMBASE to identify studies that investigated outcomes of CABG only as well as additional staged vs combined carotid interventions by both carotid endarterectomy (CEA) and carotid artery stenting (CAS)., Results: Two randomized controlled trials and 23 observational studies were included, yielding a total of 32,473 patients who underwent combined CEA and CABG (n = 20,204), CEA and staged CABG (n = 6882), CABG and staged CEA (n = 340), CAS and CABG regardless of timing and sequences (n = 1224), and CABG only (n = 3823). No strategy showed a significant advantage over CABG only in all perioperative outcomes. CEA and staged CABG was associated with the lowest perioperative stroke/transient ischemic attack (TIA) rate, significantly lower compared with CAS and CABG (odds ratio [OR], 0.52; 95% confidence interval [CI], 0.36-0.76) as well as CABG and staged CEA (OR, 0.41; 95% CI, 0.23-0.74), but was also associated with the highest perioperative mortality (OR, 2.50; 95% CI, 1.67-3.85, vs CAS and CABG) and myocardial infarction rate (OR, 3.70 [95% CI, 1.16-12.5] and OR, 2.50 [95% CI, 1.35-4.55] vs CAS and CABG, vs combined CEA and CABG, respectively)., Conclusions: CEA and staged CABG are associated with low perioperative stroke/transient ischemic attack rates with a tradeoff of higher mortality and myocardial infarction rate. No strategy showed a significant advantage over the CABG-only strategy in all perioperative outcomes, outlining the importance of a tailored approach and determining proper indications for carotid intervention in these patients., (Copyright © 2023 Society for Vascular Surgery.
