The newest-generation balloon-expandable valve, SAPIEN 3 Ultra (S3U), is expected to function well with the enhanced sealing skirt compared with SAPIEN 3 (S3). However, current literature on the comparison between these two valves is limited to short-term follow-ups. Therefore, we aimed to evaluate the 1-year outcomes and echocardiographic changes of S3U compared with S3.We retrospectively identified patients who underwent transfemoral-transcatheter aortic valve replacement with S3U or S3 (20/23/26 mm) at our institution in 2018-2020. Outcomes were 1-year clinical events and echocardiographic parameters, and were compared between S3U and S3 after adjustment with inverse probability of treatment weighting.The S3U and S3 groups included 297 (25.7%) and 858 (74.3%) patients, respectively. There were no significant differences between the two groups in clinical events (death 5.8% vs. 5.5%, hazard ratio [HR] 1.07, 95% confidence interval [CI] 0.81-1.90; death or heart failure hospitalization 10.3% vs. 10.1%, HR 1.04, 95% CI 0.67-1.62). The S3U group had a lower prevalence of mild paravalvular leakage (PVL) (13.7% vs. 22.3%, p = 0.044), with similar moderate PVL (0.7% vs. 1.2%, p 0.99). No significant differences were observed in aortic valve mean gradient and Doppler velocity index at 1 year. However, the S3U group had a larger increase in mean gradient from implantation to 1 year (median +4.70 vs. +1.63 mmHg, p 0.001).S3U and S3 carried similarly favorable clinical event risks. Nonetheless, S3U was associated with less frequent mild PVL but a larger increase in transprosthetic gradient. Further studies are needed to determine the prognostic impact of these hemodynamic differences.

New-onset left bundle branch block (LBBB) can develop after transcatheter aortic valve replacement (TAVR) resulting in worse outcomes.Describe clinical and echocardiographic outcomes with new-onset LBBB after TAVR.We included consecutive patients who underwent transfemoral-TAVR with SAPIEN-3 (S3) valve between April 2015 and December 2018. Exclusion criteria included pre-existing LBBB, right BBB, left anterior hemiblock, left posterior hemiblock, wide QRS ≥ 120ms, prior permanent pacemaker (PPM), and nontransfemoral access.Among 612 patients, 11.4% developed new-onset LBBB upon discharge. The length of stay was longer with new-onset LBBB compared with no LBBB [3 (2-5) days versus 2 (1-3) days; p 0.001]. New-onset LBBB was associated with higher rates of 30-day PPM requirement (18.6% vs. 5.4%; p 0.001) and 1-year heart failure hospitalizations (10.7% vs. 4.4%; p = 0.033). There was no difference in 3-year mortality between both groups (30.9% vs. 30.6%; p = 0.829). Further, new-onset LBBB was associated with lower left ventricular ejection fraction (LVEF) at both 30 days (55.9 ± 11.4% vs. 59.3 ± 9%; p = 0.026) and 1 year (55 ± 12% vs. 60.1 ± 8.9%; p = 0.002). These changes were still present when we stratified patients according to baseline LVEF (≥50% or50%). New-onset LBBBs were associated with a higher 1-year LV end-diastolic volume index (51.4 ± 18.6 vs. 46.4 ± 15.1 ml/mNew-onset LBBB after S3 TAVR was associated with higher PPM requirement, worse LVEF, higher LV volumes, and increased heart failure hospitalizations, with no difference in mortality.

Transcatheter aortic valve-in-valve implantation (ViV-TAVI) has emerged in recent years as a safe alternative to redo surgery in high-risk patients. Although early results are encouraging, data beyond short-term outcomes are lacking. Herein, we aimed to assess the 2-year outcomes after ViV-TAVI.Patients undergoing ViV-TAVI for degenerated surgical valves between 2013 and 2019 at the Cleveland Clinic were reviewed. The coprimary endpoints were all-cause mortality and congestive heart failure (CHF) hospitalizations. We used time-to-event analyses to assess the primary outcomes. Further, we measured the changes in transvalvular gradients and the incidence of structural valve deterioration (SVD).One hundred and eighty-eight patients were studied (mean age = 76 years; 65% males). At 2 years of follow-up, all-cause mortality and CHF hospitalizations occurred in 15 (8%) and 28 (14.9%) patients, respectively. On multivariable analysis, the postprocedural length of stay was a significant predictor for both all-cause mortality (hazard ratio [HR] = 1.1; 95% confidence interval [CI]: 1.01, 1.19) and CHF hospitalization (HR = 1.16; 95% CI: 1.07, 1.27). However, the internal diameter of the surgical valve was not associated with significant differences in both primary endpoints. For hemodynamic outcomes, nine patients (4.8%) developed SVD. The mean and peak transvalvular pressure gradients remained stable over the follow-up period.ViV-TAVI for degenerated surgical valves was associated with favorable 2-year clinical and hemodynamic outcomes. Further studies are needed to better understand the role of ViV-TAVI as a treatment option in the life management of aortic valve disease.

The cerebral embolic protection (CEP) device captures embolic debris during transcatheter aortic valve replacement (TAVR). However, the impact of CEP on stroke severity following TAVR remains unclear. Therefore, we aimed to examine whether CEP was associated with reduced severity of stroke following TAVR.This was a retrospective cohort study of 2839 consecutive patients (mean age: 79.2 ± 9.5 years, females: 41.5%) who underwent transfemoral TAVR at our institution between 2013 and 2020. We categorized patients into Sentinel CEP users and nonusers. Neuroimaging data were reviewed and the final diagnosis of a cerebrovascular event was adjudicated by a neurologist blinded to the CEP use or nonuse. We compared the incidence and severity (assessed by the National Institutes of Health Stroke Scale [NIHSS]) of stroke through 72 h post-TAVR or discharge between the two groups using stabilized inverse probability of treatment weighting (IPTW) of propensity scores.Of the eligible patients, 1802 (63.5%) received CEP during TAVR and 1037 (36.5%) did not. After adjustment for patient characteristics by stabilized IPTW, the rate of overall stroke was numerically lower in CEP users than in CEP nonusers, but the difference did not reach statistical significance (0.49% vs. 1.18%, p = 0.064). However, CEP users had significantly lower rates of moderate-or-severe stroke (NIHSS ≥ 6: 0.11% vs. 0.69%, p = 0.013) and severe stroke (NIHSS ≥ 15: 0% vs. 0.29%, p = 0.046). Stroke following CEP use (n = 8), compared with stroke following CEP nonuse (n = 15), tended to carry a lower NIHSS (median [IQR], 4.0 [2.0-7.0] vs. 7.0 [4.5-19.0], p = 0.087). Four (26.7%) out of 15 patients with stroke following CEP nonuse died within 30 days, with no death after stroke following CEP use.CEP use may be associated with attenuated severity of stroke despite no significant difference in overall stroke incidence compared with CEP nonuse. This finding is considered hypothesis-generating and needs to be confirmed in large prospective studies.

New-onset left bundle branch block (LBBB) is common after transcatheter aortic valve implantation (TAVI) but can resolve in the post-TAVI period. We sought to examine the incidence, predictors, and outcomes of early resolution of new-onset LBBB among TAVI recipients with a SAPIEN 3 (S3) valve. Among 1,203 S3-TAVI recipients without a pre-existing pacemaker or wide QRS complex at our institution between 2016 and 2019, we identified 143 patients who developed new-onset LBBB during TAVI and divided them according to the resolution or persistence of LBBB by the next day post-TAVI to compare high-degree atrioventricular block (HAVB) and permanent pacemaker (PPM) rates. Patients with resolved LBBB (n = 74, 52%), compared with those with persistent LBBB, were more often women and had a shorter QRS duration at baseline and post-TAVI, with a smaller S3 size and a shallower implantation depth. A multivariable logistic regression model demonstrated significant associations of post-TAVI QRS duration (per 10 ms increase, odds ratio = 0.60 [95% confidence interval = 0.44 to 0.82]) and implantation depth (per 1-mm-depth-increase, 0.77 [0.61 to 0.97]) with a lower likelihood of LBBB resolution. No patient with resolved LBBB developed HAVB within 30 days post-TAVI. Meanwhile, 8 patients (11.6%) with persistent LBBB developed HAVB. The 2-year PPM rate was significantly higher after persistent LBBB than after resolved LBBB (30.3% vs 4.5%, log-rank p0.001), mainly driven by higher 30-day PPM rate (18.8% vs 0.0%). In conclusion, about half of new-onset LBBBs that occurred during S3-TAVI resolved by the next day post-TAVI without HAVB. In contrast, new-onset persistent LBBB may need follow-up with ambulatory monitoring within 30 days because of the HAVB risk.

BACKGROUNDTranscatheter Edge-to-Edge Mitral Valve Repair (M-TEER) is an accepted procedure for high-risk surgical patients with degenerative and functional mitral regurgitation. Non-cardiovascular comorbidities (NCCs) are highly prevalent in patients undergoing M-TEER. Although the impact of mitral valve anatomy and cardiac comorbidities in determination of M-TEER outcomes has been studied, precise understanding of the effect of the burden of NCCs on patients undergoing M-TEER remains unclear for acute outcomes. Our objective was to identify the association of NCC comorbidity-interaction patterns in patients undergoing M-TEER on length of stay (LOS), cost of care, and in-hospital major adverse cardiovascular events (MACE).METHODS9 245 admissions from the Nationwide Readmission Database that underwent M-TEER between 2015 and 2018 were included in the study. Patients were categorized by the overall burden of non-cardiovascular comorbidities (0, 1, 2, and ≥ 3). NCC included chronic liver disease, chronic lung disease, obesity, diabetes mellitus, dementia, major depressive disorder, chronic anemia, chronic kidney disease including end-stage renal disease (ESRD) on dialysis, and malignancy. Logistic Regression and Machine Learning (ML) algorithms were used to assess associations between comorbidity burden and in-hospital MACE.RESULTSOut of 9 245 index admissions, in-hospital MACE was recorded in a total of 504 (5.3 %). Of these, the majority (30.4%) had one NCC (n = 2 861). Patients with at least three NCCs had the longest median LOS [3.0, IQR (1.0 – 11.0)] and highest median cost of hospital care [$47 275, IQR (34 175.8 – 71 149.4)]. The Gradient Boosting (GB) classifier performed the best in predicting MACE with an AUROC of 96 % (95% CI: 0.95 – 0.97). The top features of importance that predicted in-hospital MACE were admission type, number of NCCs, and age in descending order.CONCLUSIONSCalibrated GB classifier identified patients with three NCCs as the subset of admission having the highest probability of a positive MACE outcome.

This study evaluated the feasibility and safety of same-day discharge (SDD) following transfemoral transcatheter aortic valve replacement (TF-TAVR) compared with next-day discharge (NDD).Reducing hospital length of stay is an important goal for patients and hospitals. Cleveland Clinic implemented a post-TAVR SDD pathway beginning in March 2020.The study retrospectively analyzed patients who underwent "minimalist" outpatient TF-TAVR in 2019 to 2020. SDD was applied to patients who met the predefined criteria. Outcomes included in-hospital and 30-day events and were compared between SDD and NDD (during and prior to availability of the SDD pathway).In 2020, SDD and NDD accounted for 22.1% (n = 114 of 516) and 63.8% (n = 329 of 516) of outpatient TF-TAVR, respectively. SDD patients in 2020, compared with NDD patients in 2019 (n = 481), were younger, were more often male, and had a lower surgical risk. There were no significant differences in in-hospital events and 30-day readmissions (cardiovascular readmission: 3.5% vs 6.2%; P = 0.37; noncardiovascular readmission: 2.6% vs 4.0%; P = 0.78), and there were no deaths after SDD. These outcomes remained consistent after propensity score matching. Only 1 (0.9%) patient required pacemaker implantation after SDD (post-TAVR day 25). As expected based on SDD criteria, multivariable logistic regression analysis identified procedure end-time as the strongest predictor of SDD (adjusted OR: 7.74; 95% CI: 4.39-13.63), while male sex and baseline hemoglobin level were also associated with SDD.SDD after TF-TAVR was feasible in this early experience without impairing post-discharge safety. Our SDD pathway may serve as a useful strategy to improve bed utilization and reduce hospital stay for TAVR recipients.

Background Limited data are available regarding clinical outcomes of valve-in-valve (ViV) transcatheter aortic valve implantation (TAVI) following the United States Food and Drug Administration approval of ViV TAVI in 2015. Aims The aim of this study was to evaluate in-hospital, 30-day, and 6-month outcomes of ViV TAVI versus repeat surgical aortic valve replacement (SAVR) in patients with a failed aortic bioprosthetic valve. Methods This retrospective cohort study identified patients who underwent ViV TAVI or repeat SAVR utilising the Nationwide Readmission Database from 2016 to 2018. Primary outcomes were all-cause readmission (at 30 days and 6 months) and in-hospital death. Secondary outcomes were in-hospital stroke, pacemaker implantation, 30-day/6-month major adverse cardiac events (MACE), and mortality during readmission. Propensity score-matching (inverse probability of treatment weighting) analyses were implemented. Results Out of 6,769 procedures performed, 3,724 (55%) patients underwent ViV TAVI, and 3,045 (45%) underwent repeat SAVR. ViV TAVI was associated with lower in-hospital all-cause mortality (odds ratio [OR] 0.42, 95% confidence interval [CI]: 0.20-0.90, p=0.026) and a higher rate of 30-day (hazard ratio [HR] 1.46, 95% CI: 1.13-1.90, p=0.004) and 6-month all-cause readmission (HR 1.54, 95% CI: 1.14-2.10, p=0.006) compared with repeat SAVR. All secondary outcomes were comparable between the two groups. Conclusions ViV TAVI was associated with lower in-hospital mortality but higher 30-day and 6-month all-cause readmission. However, there was no difference in risk of in-hospital stroke, post-procedure pacemaker implantation, MACE, and mortality during 30-day and 6-month readmission compared with repeat SAVR, suggesting that ViV TAVI can be performed safely in carefully selected patients.

Little is known about the utility of transcatheter aortic valve implantation (TAVI) in patients with cirrhosis of the liver, and their outcomes have not been studied extensively in literature. We performed a retrospective analysis of patients with severe symptomatic aortic stenosis (AS) who underwent transfemoral TAVI with a SAPIEN 3 valve at our institution between April 2015 and December 2018. We identified 32 consecutive patients with evidence of cirrhosis of the liver on imaging (including ultrasound and/or computed tomography) and patients with severe symptomatic AS who underwent transfemoral TAVI with a SAPIEN 3 valve. Among 1,028 patients, 32 had cirrhosis of the liver and 996 constituted the control group without cirrhosis. Mean age in the cirrhosis group was 74.5 years compared with 81.2 years in the control group. Baseline variables were comparable between the groups. Compared with the noncirrhotic group, patients with cirrhosis had a similar 1-year mortality (12% vs 12%, p = 1), a lower 30-day new pacemaker after TAVI rate (6% vs 9%, p = 0.85), a higher 30-day and 1-year readmission rate for heart failure (11% vs 1% and 12% vs 5%, p = 0.12, respectively), and a similar 1-year major adverse cardiac and cerebrovascular event rate (15% vs 14%, p = 0.98). In conclusion, patients with severe AS with concomitant liver cirrhosis who underwent TAVI demonstrated comparable outcomes to their noncirrhotic counterparts.

The aim of this study was to compare the prevalence and real-world outcomes of patients who require peripheral vascular intervention during the same hospitalization as transcatheter aortic valve replacement (TAVR) compared with TAVR alone.There are limited data on the prevalence and outcomes of combined TAVR and percutaneous peripheral vascular intervention.All patients who underwent TAVR in 2016 and 2017 were identified using the Nationwide Readmissions Database. Outcomes of patients undergoing TAVR alone were compared with those of patients undergoing combined TAVR and peripheral intervention, TAVR and peripheral intervention with and without a history of peripheral artery disease, and alternative-access TAVR with transfemoral TAVR in individuals undergoing peripheral intervention. The primary outcome was in-hospital mortality.A total of 99,654 hospitalizations were identified, among which 4,397 patients (4.42%) underwent peripheral intervention during the same admission as TAVR. Patients who required peripheral intervention had increased mortality (4.2% vs 1.5%; P 0.001), stroke (3.5% vs 1.8%; P 0.001), acute kidney injury (17.6% vs 10.8%; P 0.001), blood transfusion (16.0% vs 11.3%; P 0.001), 30-day readmission (16.3% vs 12.1%; P 0.001), median length of stay (4 days [IQR: 2-8 days] vs 3 days [IQR: 2-5 days]; P 0.001), and hospitalization charges. Compared with patients undergoing peripheral intervention to facilitate transfemoral TAVR, alternative-access TAVR was associated with increased mortality (4.6% vs 3.0%; P = 0.036), acute kidney injury (22.7% vs 14.3%; P 0.001), median length of stay (5 days [IQR: 3-10 days] vs 4 days [IQR: 2-7 days]; P 0.001), and 30-day readmission (18.1% vs 15.5%; P = 0.012).Peripheral vascular intervention may be used to facilitate transfemoral access or as a bailout for vascular complications during TAVR. Combined TAVR and peripheral intervention is associated with an increased risk for adverse events, though outcomes are better compared with alternative-access TAVR using a nonfemoral approach.

Permanent pacemaker (PPM) implantation is required in 5% to 10% of patients following transcatheter aortic valve implantation (TAVI). However, there are limited data on the impact of PPM implantation on the incidence of pericardial effusion, cardiac tamponade, and outcomes after TAVI. We identified all hospitalizations in patients ≥18 years of age who underwent TAVI in the years 2016 to 2017 in the Nationwide Readmission Database. The endpoints of the study were pericardial effusion, cardiac tamponade, and percutaneous or surgical drainage of the pericardial cavity in patients that required PPM implantation after TAVI. Multivariable logistic regression determined associations of PPM implantation, pericardial effusion, and tamponade with patient outcomes. A total of 54,317 unweighted hospitalizations for TAVI were identified, of which 5,639 (10.4%) required PPM. The risk of pericardial effusion was significantly greater in patients who required PPM (2.4% vs 1.6%, adjusted odds ratio (aOR) 1.39 (1.15 to 1.70), p

A well conducted randomised controlled trial (RCT) is extremely important in the field of cardiovascular medicine. At the same time, it is equally important to understand the strengths and limitations of any RCT, and internal variability is a concept in clinical trials that is poorly understood. Variability in a clinical trial may be introduced at an individual level or during measurement, sampling, or conduct of the trial. It is not the same as internal validity, which is a broader concept of accuracy; to be valid, a study should minimise variability and have sound methodology. There are various steps that may be followed to minimise the internal variability in a clinical trial. One aspect of great importance is the adjudication process, which should be done meticulously and is often a step that is overlooked. It is important to standardise each step as much as possible, to ensure consistency and reduce noise at all levels. The concepts discussed in this review may serve as a roadmap to limit the influence of internal variability and maximise internal validity of RCT results.

Balloon aortic valvuloplasty (BAV) is often performed for patients with aortic stenosis who are not candidates for transcatheter aortic valve replacement (TAVR) due to concomitant medical issues. H...

Coronavirus disease (COVID-19), first identified in Wuhan, China, in December 2019, is now a pandemic, having already spread to 188 countries, with more than 28,280,000 infections worldwide. Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is the responsible infectious agent, and similar to other human coronaviruses, uses membrane-bound angiotensin-converting enzyme 2 (membrane-bound ACE2) for entry into the host cells. COVID-19 has important cardiovascular implications, especially for patients with pre-existing cardiovascular co-morbidities, potentially mediated through several mechanisms, including direct myocardial injury, worsening of those pre-existing cardiovascular co-morbidities, and adverse cardiovascular effects of potential therapies for COVID-19. The disease is causing a significant burden on health systems worldwide. Elective surgeries and procedures were postponed for a considerable period of time, and many patients with known cardiovascular disease (CVD) risk factors presented late to hospitals, for fear of contracting COVID-19, with serious adverse consequences. Significant negative impact on a population level is highlighted by prolonged isolation, decreased exercise and physical activity, and higher levels of depression and anxiety, all predisposing to elevated cardiovascular risk. This article provides a timely overview of COVID-19 and its impact on the cardiovascular system, focusing on the pathogenesis, potential adverse cardiovascular events, the potential treatment options, protection for health care providers and patients, and what the cardiovascular community could do to mitigate the impact of COVID-19.

Excimer laser coronary atherectomy (ELCA) during percutaneous coronary intervention (PCI) has been in use for more than twenty years. While early experiences were not favorable over balloon angioplasty alone, with improvement in operator technique, patient selection and technology, ELCA has established its own niche in contemporary PCI as a safe and effective atherectomy strategy. With growing experience in complex coronary interventions worldwide, ELCA has become one of the essential atherectomy tools offering unique advantages over other atherectomy devices. In the modern era, ELCA is commonly used for patients with in-stent restenosis, stent under expansion, balloon uncrossable lesions and chronic total occlusions. Technical success rates are reported to be >80% in most situations while procedural complication rates such as vessel dissection and perforation among others are reported to average 9% over the past 25 years with improvement over time. In this review, we provide a comprehensive systematic review of the ELCA system, its practical use, indications, and procedural techniques in the contemporary PCI era.

Background Rheumatic immune mediated inflammatory diseases (IMIDs) are associated with high risk of acute coronary syndrome. The long‐term prognosis of acute coronary syndrome in patients with rheumatic IMIDs is not well studied. Methods and Results We identified Medicare beneficiaries admitted with a primary diagnosis of myocardial infarction (MI) from 2014 to 2019. Outcomes of patients with MI and concomitant rheumatic IMIDs including systemic lupus erythematosus, rheumatoid arthritis, systemic sclerosis, dermatomyositis, or psoriasis were compared with propensity matched control patients without rheumatic IMIDs. One‐to‐three propensity‐score matching was done for exact age, sex, race, ST‐segment–elevation MI, and non–ST‐segment–elevation MI variables and greedy approach on other comorbidities. The study primary outcome was all‐cause mortality. The study cohort included 1 654 862 patients with 3.6% prevalence of rheumatic IMIDs, the most common of which was rheumatoid arthritis, followed by systemic lupus erythematosus. Patients with rheumatic IMIDs were younger, more likely to be women, and more likely to present with non–ST‐segment–elevation MI. Patients with rheumatic IMIDs were less likely to undergo coronary angiography, percutaneous coronary intervention or coronary artery bypass grafting. After propensity‐score matching, at median follow up of 24 months (interquartile range 9–45), the risk of mortality (adjusted hazard ratio [HR], 1.15 [95% CI, 1.14–1.17]), heart failure (HR, 1.12 [95% CI 1.09–1.14]), recurrent MI (HR, 1.08 [95% CI 1.06–1.11]), and coronary reintervention (HR, 1.06 [95% CI, 1.01–1.13]) ( P Conclusions Patients with MI and rheumatic IMIDs have higher risk of mortality, heart failure, recurrent MI, and need for coronary reintervention during follow‐up compared with patients without rheumatic IMIDs.

In this review, the authors discuss a brief history of the Impella mechanical circulatory support device, a mechanistic role for the device in the context of the underlying pathophysiology of acute myocardial infarction cardiogenic shock (AMI-CS), the current body of literature evaluating its role in AMI-CS, and upcoming efforts to identify a role more clearly for the device in AMI-CS.

BackgroundPatients undergoing transcatheter aortic valve implantation (TAVI) often have multiple comorbidities, such as anaemia and chronic inflammatory disorders. We sought to investigate the association between preoperative and postoperative haematological parameters and clinical outcomes in TAVI patients at mid-term follow-up.MethodsIn the present study, consecutive patients (N=908) who underwent TAVI at the Cleveland Clinic between 2017 and 2019 with available complete blood counts were studied. Data were collected on preoperative and postoperative anaemia and elevations in neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR). Survival analysis was used to study the association of haematologic parameters with all-cause mortality and major adverse cardiac and cerebrovascular events (MACCE).ResultsWe found that preoperative anaemia and elevated NLR were significantly associated with a higher risk of all-cause mortality (aHR=1.6 (95% CI: 1.1 to 2.0) and 1.4 (95% CI: 1.1 to 1.6), respectively) and MACCE (aHR=1.9 (95% CI: 1.3 to 2.8) and 1.6 (95% CI: 1.1 to 2.4), respectively). While an elevated preoperative PLR was not associated with increased mortality risk, it had a significant association with MACCE risk (aHR: 1.6 (95% CI: 1.1 to 2.4)). Further, postoperative anaemia, elevated NLR and PLR were associated with increased risks of all-cause mortality and MACCE.ConclusionPathological alterations in haematological parameters were associated with higher risks of post-TAVI mortality and MACCE at mid-term follow-up. Our findings advocate for further incorporating haematological parameters in the preoperative evaluation of TAVI candidates.

The ideal antithrombotic therapy post transcatheter aortic valve replacement (TAVR) remains uncertain. We performed a network meta-analysis of RCTs to report the outcomes with various antithrombotic strategies to determine the optimal therapy. A systematic search of the PubMed/Medline and Cochrane databases was performed through January 6, 2022. The primary outcome was stroke and the secondary outcomes were major/life-threatening bleeding, myocardial infarction, all-cause mortality, and cardiac mortality. A network meta-analysis was conducted with a random-effects model. All analysis was carried out using R version 4.0.3. Six RCTs were included in the final analysis. SAPT when compared with DAPT was associated with a reduced risk of major or life-threatening bleeding [OR: 0.42; 95% CI: 0.25-0.70]. Other antithrombotic strategies were associated with similar odds of major and life-threatening bleeding post TAVR compared with DAPT. There was no difference in the incidence of stroke, myocardial infarction, all-cause and cardiac mortality between the various antithrombotic strategies post TAVR. The present analysis reported SAPT as the preferred antithrombotic regimen post TAVR compared with other regimens in patients who do not have other indications for anticoagulation. Additional studies such as ADAPT-TAVR, CLOE and ATLANTIS trials will further add to our understanding of the adequate antithrombotic regimen post TAVR in patients with otherwise no indication for anticoagulation.

Current evidence is limited to small studies describing the association between cardiac injury and outcomes in patients with coronavirus disease 2019 (COVID-19). To address this, we performed a comprehensive meta-analysis of studies in COVID-19 patients to evaluate the association between cardiac injury and all-cause mortality, intensive care unit (ICU) admission, mechanical ventilation, acute respiratory distress syndrome, acute kidney injury and coagulopathy. Further, studies comparing cardiac biomarker levels in survivors versus nonsurvivors were included. A total of 14 studies (3,175 patients) were utilized for the final analysis. Cardiac injury in patients with COVID-19 was associated with higher risk of mortality (risk ratio [RR]:7.79; 95% confidence interval [CI]: 4.69 to 13.01; I2=58%), ICU admission (RR: 4.06; 95% CI: 1.50 to 10.97; I2 = 61%), mechanical ventilation (RR: 5.53; 95% CI: 3.09 to 9.91; I2 = 0%), and developing coagulopathy (RR: 3.86; 95% CI:2.81 to 5.32; I2 = 0%). However, cardiac injury was not associated with increased risk of acute respiratory distress syndrome (RR:3.22; 95% CI:0.72 to 14.47; I2 = 73%) or acute kidney injury (RR: 11.52, 95% CI:0.03 to 4,159.80; I2 = 0%). The levels of hs-cTnI (MD:34.54 pg/ml;95% CI: 24.67 to 44.40 pg/ml; I2 = 88%), myoglobin (MD:186.81 ng/ml; 95% CI: 121.52 to 252.10 ng/ml; I2 = 88%), NT-pro BNP (MD:1183.55 pg/ml; 95% CI: 520.19 to 1846.91 pg/ml: I2 = 96%) and CK-MB (MD:2.49 ng/ml;95% CI: 1.86 to 3.12 ng/ml; I2 = 90%) were significantly elevated in nonsurvivors compared with survivors with COVID-19 infection. The results of this meta-analysis suggest that cardiac injury is associated with higher mortality, ICU admission, mechanical ventilation and coagulopathy in patients with COVID-19.

OBJECTIVE We studied the utilization of home health care (HHC) among acute myocardial infarction (AMI) patients, impact of HHC on and predictors of 30-day readmission. METHODS We queried the National Readmission Database (NRD) from 2012 to 2014identify patients with AMI discharged home with (HHC+) and without HHC (HHC-). Linkage provided in the data identified patients who had 30-day readmission, our primary end-point. The probability for each patient to receive HHC was calculated by a multivariable logistic regression. Average treatment of treated weights were derived from propensity scores. Weight-adjusted logistic regression was used to determine impact of HHC on readmission. RESULTS A total of 406 237 patients with AMI were discharged home. Patients in the HHC+ cohort (38 215 patients, 9.4%) were older (mean age 77 vs. 60 years P < 0.001), more likely women (53 vs. 26%, P < 0.001), have heart failure (5 vs. 0.5%, P < 0.001), chronic kidney disease (26 vs. 6%, P < 0.001) and diabetes (35 vs. 26%, P < 0.001). Patients readmitted within 30-days were older with higher rates of diabetes (RR = 1.4, 95% CI: 1.37-1.48) and heart failure (RR = 5.8, 95% CI: 5.5-6.2). Unadjusted 30-day readmission rates were 21 and 8% for HHC+ and HHC- patients, respectively. After adjustment, readmission was lower with HHC (21 vs. 24%, RR = 0.89, 95% CI: 0.82-0.96; P < 0.001). CONCLUSION In the United States, AMI patients receiving HHC are older and have more comorbidities; however, HHC was associated with a lower 30-day readmission rate.

Mortality in patients with STEMI-associated cardiogenic shock (CS) is increasing. Whether a comprehensive ST-elevation myocardial infarction (STEMI) protocol (CSP) can improve their care delivery and mortality is unknown. We evaluated the impact of a CSP on incidence and outcomes in patients with STEMI-associated CS. We implemented a 4-step CSP including: (1) Emergency Department catheterization lab activation; (2) STEMI Safe Handoff Checklist; (3) immediate catheterization lab transfer; (4) and radial-first percutaneous coronary intervention (PCI). We studied 1,272 consecutive STEMI patients who underwent PCI and assessed for CS incidence per National Cardiovascular Data Registry definitions within 24-hours of PCI, care delivery, and mortality before (January 1, 2011, to July 14, 2014; n = 723) and after (July 15, 2014, to December 31, 2016; n = 549) CSP implementation. Following CSP implementation, CS incidence was reduced (13.0% vs 7.8%, p = 0.003). Of 137 CS patients, 43 (31.4%) were in the CSP group. CSP patients had greater IABP-Shock II risk scores (1.9 ± 1.8 vs 2.8 ± 2.2, p = 0.014) with otherwise similar hemodynamic and baseline characteristics, cardiac arrest incidence, and mechanical circulatory support use. Administration of guideline-directed medical therapy was similar (89.4% vs 97.7%, p = 0.172) with significant improvements in trans-radial PCI (9.6% vs 44.2%, p < 0.001) and door-to-balloon time (129.0 [89:160] vs 95.0 [81:116] minutes, p = 0.001) in the CSP group, translating to improvements in infarct size (CK-MB 220.9 ± 156.0 vs 151.5 ± 98.5 ng/ml, p = 0.005), ejection fraction (40.8 ± 14.5% vs 46.7 ± 14.6%, p = 0.037), and in-hospital mortality (30.9% vs 14.0%, p = 0.037). In conclusion, CSP implementation was associated with improvements in CS incidence, infarct size, ejection fraction, and in-hospital mortality in patients with STEMI-associated CS. This strategy offers a potential solution to bridging the historically elusive gap in their care.

Transesophageal echocardiography plays a central role in the evaluation and guidance of mitral valve interventions. Our case highlights the importance of thorough intraprocedural valve evaluation using 3-dimensional and multiplanar reconstruction transesophageal echocardiography, discovering an unexpected mechanism for mitral regurgitation, to guide an alternative intervention strategy by an experienced interventional team.

Background The role of invasive management compared with medical management in patients with non–ST‐segment–elevation myocardial infarction (NSTEMI) and advanced chronic kidney disease (CKD) is uncertain, given the increased risk of procedural complications in patients with CKD. We aimed to compare clinical outcomes of invasive management with medical management in patients with NSTEMI‐CKD. Methods and Results We identified NSTEMI and CKD stages 3, 4, 5, and end‐stage renal disease admissions using International Classification of Diseases, Tenth Revision, Clinical Modification ( ICD‐10‐CM ) codes from the Nationwide Readmission Database 2016 to 2018. Patients were stratified into invasive and medical management. Primary outcome was mortality (in‐hospital and 6 months after discharge). Secondary outcomes were in‐hospital postprocedural complications (acute kidney injury requiring dialysis, major bleeding) and postdischarge 6‐month safety and major adverse cardiovascular events. Out of 141 052 patients with NSTEMI‐CKD, 85 875 (60.9%) were treated with invasive management, whereas 55 177 (39.1%) patients were managed medically. In propensity‐score matched cohorts, invasive strategy was associated with lower in‐hospital (CKD 3: odds ratio [OR], 0.47 [95% CI, 0.43–0.51]; P P P =0.096; end‐stage renal disease: OR, 0.51 [95% CI, 0.46–0.56]; P Conclusions Invasive management was associated with lower mortality and major adverse cardiovascular events but minimal increased in‐hospital complications in patients with NSTEMI‐CKD compared with medical management, suggesting patients with NSTEMI‐CKD should be offered invasive management.

BACKGROUND: Limited information is available on outcomes in patients with bicuspid aortic valve (BAV) stenosis undergoing transcatheter aortic valve implantation (TAVI) compared with surgical aortic valve replacement (SAVR), as pivotal randomised trials excluded patients with BAV pathology due to anatomic complexity. AIMS: The aim of the study was to compare early outcomes between TAVI and SAVR in patients with BAV stenosis. METHODS: We queried the Nationwide Readmission Database (NRD) between 2016 and 2018 to identify adults who underwent TAVI or SAVR for BAV stenosis. The study’s primary outcome was in-hospital mortality. Secondary outcomes were 30-day and six-month major adverse cardiovascular events (MACE). We matched both cohorts using propensity score matching, and applied logistic and Cox-proportional hazard regression to compute the odds ratio (OR), the hazard ratio (HR), and the 95% confidence interval (CI). RESULTS: Out of 17,068 patients with BAV stenosis, 1,629 (9.5%) patients underwent TAVI and 15,439 (90.5%) underwent SAVR. After propensity score matching (PSM), we found 1,393 matched pairs. Of the matched pairs, 848 had complete six-month follow-ups. In the PSM cohort, TAVI was associated with reduced in-hospital mortality (0.7% vs 1.8%, OR: 0.35, 95% CI: 0.13-0.93; p=0.035), and a similar rate of MACE at 30 days (1% vs 1.5%, OR: 0.65, 95% CI: 0.27-1.58; p=0.343) and at six months (4.2% vs 4.9%, HR 0.86, 95% CI: 0.44-1.69; p=0.674), compared with SAVR. CONCLUSIONS: In the propensity score-matched cohort, TAVI was associated with reduced odds of in-hospital mortality and a similar risk of 30-day and six-month MACE, supporting the feasibility of TAVI in BAV patients without a need for concurrent aortic root repair.
