Introduction: Proper management of thoracic drainages is essential in the recovery of patients after lung resection. This study evaluates the concordance in decision-making for drain removal depending on the type of drainage system used and the previous experience of the personnel., Material and Methods: Prospective, comparative, and stratified randomization study on interobserver variability between senior specialist doctors and inexperienced healthcare personnel in the removal of thoracic drains in patients undergoing lung resection connected to conventional systems (CS) or digital systems (DS) with continuous recording. The withdrawal criteria were established before the study, and decisions were recorded during three postoperative days., Results: 75 patients were included, 38 CS and 37 DS, with no statistically significant differences in sex distribution, age, intervention performed, presence of pleuropulmonary adhesions, drain time, or post-extraction complications between the groups. The overall concordance in drain removal decisions was moderate (kappa = 0.452), with notable variations in concordance depending on the drainage system used: CS (kappa = 0.188) with an overall agreement rate of 61.7% compared to DS (kappa = 0.716) with an overall agreement rate of 86.4%. Digital systems showed substantial concordance regardless of the operator's experience, with kappa values indicating high concordance on all postoperative days., Conclusions: The use of digital systems for managing thoracic drains significantly improves concordance in clinical decision-making regardless of the experience level. These findings suggest that adopting digital systems not only optimizes patient safety but also reduces the dependence on highly specialized healthcare professionals., Competing Interests: Declaration of competing interest The authors have no conflicts of interests to declare., (Copyright © 2024 AEC.

Background: Patients with aortic stenosis may continue to have an increased risk of heart failure, arrhythmias, and death after successful transcatheter aortic valve implantation. Renin-angiotensin system inhibitors may be beneficial in this setting. We aimed to explore whether ramipril improves the outcomes of patients with aortic stenosis after transcatheter aortic valve implantation., Methods and Results: PROBE (Prospective Randomized Open, Blinded Endpoint) was a multicenter trial comparing ramipril with standard care (control) following successful transcatheter aortic valve implantation in patients with left ventricular ejection fraction >40%. The primary end point was the composite of cardiac mortality, heart failure readmission, and stroke at 1-year follow-up. Secondary end points included left ventricular remodeling and fibrosis. A total of 186 patients with median age 83 years (range 79-86), 58.1% women, and EuroSCORE-II 3.75% (range 3.08-4.97) were randomized to receive either ramipril (n=94) or standard treatment (n=92). There were no significant baseline, procedural, or in-hospital differences. The primary end point occurred in 10.6% in the ramipril group versus 12% in the control group ( P =0.776), with no differences in cardiac mortality (ramipril 1.1% versus control group 2.2%, P =0.619) but lower rate of heart failure readmissions in the ramipril group (3.2% versus 10.9%, P =0.040). Cardiac magnetic resonance analysis demonstrated better remodeling in the ramipril compared with the control group, with greater reduction in end-systolic and end-diastolic left ventricular volumes, but nonsignificant differences were found in the percentage of myocardial fibrosis., Conclusions: Ramipril administration after transcatheter aortic valve implantation in patients with preserved left ventricular function did not meet the primary end point but was associated with a reduction in heart failure re-admissions at 1-year follow-up., Registration: URL: https://www.clinicaltrials.gov; Unique Identifier: NCT03201185.

Background: Optimal strategies to manage embolization of transcatheter aortic valve implantation (TAVI) devices are unclear; valve-in-valve (ViV) is often used. We aimed to describe through one-single center experience its rate, causes, consequences, and management as well as the rate and relevance of commissural alignment (CA) in this context., Methods: We identified across 1038 TAVI cases, those cases requiring ViV for the management of first device embolization. CA (absence or mild misalignment) after first and second device was assessed by CT or fluoroscopy., Results: A total of 23 cases (2.2%) were identified, 52.3% embolized towards the aorta and 47.7% towards the ventricle. Suboptimal implant height (38%) and embolization at the time of post-dilation (23%) were the most frequent mechanisms together with greater rate of bicuspid valve (p < 0.001) and a trend to greater annular eccentricity. Procedural and 1-year death occurred in 13% and 34%, respectively (vs. 1.1% and 7.8% in the global cohort, p < 0.001). CA was present in 76.9% of the prostheses initially implanted but was only spontaneously achieved in 30.8% of the second ViV device. Adequate CA of both prostheses was identified in only two cases (8.7%). There were no cases of coronary obstruction., Conclusions: TAVI device embolization mechanisms can often be predicted and prevented. Mortality following bail-out ViV is higher than in regular TAVI procedures but 2/3 of these patients survived beyond 1-year follow-up. In them, valve degeneration or coronary re-access might be particularly challenging since CA was rarely achieved with both devices suggesting that greater efforts should be made in this regard., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Elsevier B.V.

Objectives: To evaluate the prognostic value of transit time (TT) assessment in the systemic circulation and organ perfusion in patients with ventricular dysfunction (VD). The primary endpoint was defined as death, heart failure admission, or ventricular arrhythmias, and the secondary endpoint was worsening renal function., Methods: A retrospective study on 139 patients who underwent cardiac magnetic resonance for VD evaluation and 50 controls. TT was measured as peak-to-peak time in signal intensity over time curves obtained at different stages of circulation (right cavities, left cavities, aorta, and peripheral organs) from first-pass perfusion images. Outcomes were monitored over a median follow-up of 15 months., Results: A total of 139 patients were included (84% male, age 63 [57-70] years). Patients exhibited significantly prolonged TT compared to controls, with in-patients showing longer times than outpatients. Among the 29 patients reaching the primary endpoint, both PTT and STT were significantly prolonged (PTT: 9.75 s vs 13.4 s, p < 0.01; STT: 4.77 s vs 7.00 s, p < 0.01). Concurrent prolongation of PTT (> 10 s) and STT (> 5 s) was associated with a higher event probability (42.3%), compared to isolated abnormalities (6.3% for PTT, 6.7% for STT). Multivariate analysis revealed that combined PTT and STT alteration independently predicted the combined endpoint (HR IC 95%: 8.685 (2.415-31.236), p = 0.001). Prolonged RPT was independently associated with renal function deterioration (OR IC 95%: 1.129 (1.015-1.256), p = 0.024)., Conclusions: Evaluation of TT beyond pulmonary circulation provides prognostic insights into VD. Simultaneous assessment of PTT and STT enhances specificity compared to isolated PTT evaluation, predicting combined adverse events. RPT is independently associated with renal impairment., Clinical Relevance Statement: For the first time, it is described that transit time can be evaluated in systemic circulation and in peripheral organs and that this assessment can be easily made from conventional CMR perfusion images and holds significant prognostic value., Key Points: Pulmonary transit time is a valuable hemodynamic parameter; systemic transit time may also be valuable. Transit time can be measured in the systemic circulation, and is longer in patients with ventricular dysfunction. Systemic transit time assessed by magnetic resonance imaging identifies patients with ventricular dysfunction who will experience events during follow-up., (© 2024.

Background: Quantitative flow ratio (QFR) virtual angioplasty with pre-PCI residual QFR showed better results compared with an angiographic approach to assess post-PCI functional results. However, correlation with pre-PCI residual QFR and post-PCI fractional flow reserve (FFR) is lacking. Methods: A multicenter prospective study including consecutive patients with angiographically 50-90% coronary lesions and positive QFR results. All patients were evaluated with QFR, hyperemic and non-hyperemic pressure ratios (NHPR) before and after the index PCI. Pre-PCI residual QFR (virtual angioplasty) was calculated and compared with post-PCI fractional flow reserve (FFR), QFR and NHPR. Results: A total of 84 patients with 92 treated coronary lesions were included, with a mean age of 65.5 ± 10.9 years and 59% of single vessel lesions being the left anterior descending artery in 69%. The mean vessel diameter was 2.82 ± 0.41 mm. Procedural success was achieved in all cases, with a mean number of implanted stents of 1.17 ± 0.46. The baseline QFR value was 0.69 ± 0.12 and baseline FFR and NHPR were 0.73 ± 0.08 and 0.82 ± 0.11, respectively. Mean post-PCI FFR increased to 0.87 ± 0.05 whereas residual QFR had been estimated as 0.95 ± 0.05, showing poor correlation with post-PCI FFR (0.163; 95% CI:0.078-0.386) and low diagnostic accuracy (30.9%, 95% CI:20-43%). Conclusions: In this analysis, the results of QFR-based virtual angioplasty did not seem to accurately correlate with post-PCI FFR.

There are known pathophysiologic and clinical differences according to sex in patients with aortic stenosis (AS). To evaluate if these differences persist after valve replacement, we conducted an observational study including 451 patients with symptomatic AS who survived aortic valve intervention (AVI) in two centers. Clinical data and mortality were evaluated at a mean follow-up of 5 years. 56% of patients were women. At baseline, women were older (80.6 vs. 78 years, p = 0.013), presented higher mean gradient (48 vs. 45 mmHg, p = 0.023), lower aortic valve area (0.70 vs. 0.74 cm 2 , p = 0.002) and higher systolic pulmonary artery pressure (36 vs. 33 mmHg, p = 0.016). They underwent percutaneous aortic valve replacement more frequently than men (47 vs. 35.9%, p = 0.017). At 5 years follow-up, women required more admissions due to heart failure (23 vs. 9%, p = 0.046) but they did not present higher cardiovascular nor overall mortality (27.7% vs. 29.8%, p = 0.741; 11.1 vs. 10.1%, p = 0.619, respectively). Female sex was an independent predictor of heart failure hospitalization at follow-up (HR 95% 1.16-4.22, p = 0.016). Women undergo AVI at a more advanced stage than men, resulting in a higher frequency of readmissions due to heart failure during the follow-up period, but not in higher mortality.

Introduction and Objectives: No comparisons have been published yet regarding the newest iteration of balloon- and self-expandable transcatheter heart valves for the treatment of bicuspid aortic valve (BAV) stenosis., Methods: Multicenter registry of consecutive patients with severe BAV stenosis treated with balloon-expandable transcatheter heart valves (Myval and SAPIEN 3 Ultra, S3U) or self-expanding Evolut PRO+(EP+). TriMatch analysis was carried out to minimize the impact of baseline differences. The primary endpoint of the study was 30-day device success, and the secondary endpoints were the composite and individual components of early safety at 30 days., Results: A total of 360 patients (age 76.6±7.6 years, 71.9% males) were included: 122 Myval (33.9%), 129 S3U (35.8%), and 109 EP+(30.3%). The mean STS score was 3.6±1.9%. There were no cases of coronary artery occlusion, annulus rupture, aortic dissection, or procedural death. The primary endpoint of device success at 30 days was significantly higher in the Myval group (Myval: 100%; S3U: 87.5%; and EP+: 81.3%), mainly due to higher residual aortic gradients with S3U and greater≥moderate aortic regurgitation (AR) with EP+. No significant differences were found in the unadjusted rate of pacemaker implantation., Conclusions: In patients with BAV stenosis deemed unsuitable for surgery, Myval, S3U and EP+showed similar safety but balloon-expandable Myval had better gradients than S3U, and both balloon-expandable devices had lower residual AR than EP+, suggesting that, taking into consideration the patient-specific risks, any of these devices can be selected with optimal outcomes., (Copyright © 2023.

Objective: The recurrence of syncope after valve intervention in severe aortic stenosis (SAS) and its impact on outcome are unknown. We hypothesised that syncope on exertion will disappear after intervention, whereas syncope at rest might recur. Our aim has been to describe the recurrence of syncope in patients with SAS undergoing valve replacement and its impact on mortality., Methods: Double-centre observational registry of 320 consecutive patients with symptomatic SAS without other valve disease and/or coronary artery disease who underwent valve intervention and were discharged alive. All-cause mortality and cardiovascular mortality were considered events., Results: 53 patients (median age 81 years, 28 men) had syncope (29 on exertion, 21 at rest, 3 unknown). Clinical and echocardiographic variables were similar in patients with and without syncope (median v max 4.44 m/s, mean gradient 47 mm Hg, valve area 0.7 cm 2 , left ventricular ejection fraction 62%). After a median follow-up of 69 months (IQR: 55-88), syncope on exertion did not recur in any patient. In contrast, 8 of the 21 patients with syncope at rest had postintervention syncope at rest (38%; p<0.001): 3 needed a pacemaker, 3 were neuromediated or hypotensive and 2 arrhythmic. Only recurrence of syncope was associated with cardiovascular mortality (HR 5.74; 95% CI 2.17 to 15.17; p<0.001)., Conclusions: Syncope on exertion in patients with SAS did not recur after aortic valve intervention. Syncope at rest recurs in a high proportion of patients and identifies a population with increased mortality. According to our results, syncope at rest should be thoroughly evaluated before proceeding to aortic valve intervention., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Recent works have demonstrated a significant reduction in cholesterol levels and increased oxidative stress in patients with coronavirus disease 2019 (COVID-19). The cause of this alteration is not well known. This study aimed to comprehensively evaluate their possible association during the evolution of COVID-19. This is an observational prospective study. The primary endpoint was to analyze the association between lipid peroxidation, lipid, and inflammatory profiles in COVID-19 patients. A multivariate regression analysis was employed. The secondary endpoint included the long-term follow-up of lipid profiles. COVID-19 patients presented significantly lower values in their lipid profile (total, low, and high-density lipoprotein cholesterol) with greater oxidative stress and inflammatory response compared to the healthy controls. Lipid peroxidation was the unique oxidative parameter with a significant association with the total cholesterol (OR: 0.982; 95% CI: 0.969-0.996; p = 0.012), IL1-RA (OR: 0.999; 95% CI: 0.998-0.999; p = 0.021) IL-6 (OR: 1.062; 95% CI: 1.017-1.110; p = 0.007), IL-7 (OR: 0.653; 95% CI: 0.433-0.986; p = 0.042) and IL-17 (OR: 1.098; 95% CI: 1.010-1.193; p = 0.028). Lipid abnormalities recovered after the initial insult during long-term follow-up (IQR 514 days); however, those with high LPO levels at hospital admission had, during long-term follow-up, an atherogenic lipid profile. Our study suggests that oxidative stress in COVID-19 is associated with derangements of the lipid profile and inflammation. Survivors experienced a recovery in their lipid profiles during long-term follow-up, but those with stronger oxidative responses had an atherogenic lipid profile.

Introduction and Objectives: Transcatheter edge-to-edge repair (TEER) should be considered in patients with heart failure and secondary mitral regurgitation (MR). Angiotensin receptor-neprilysin inhibitors (ARNIs) have been demonstrated to improve prognosis in heart failure. We aimed to evaluate the impact ARNIs on patient selection and outcomes., Methods: The population of the Spanish TEER prospective registry (March 2012 to January 2021) was divided into 2 groups: a) TEER before the ARNI era (n=450) and b) TEER after the recommendation of ARNIs by European Guidelines (n=639), with further analysis according to intake (n=52) or not (n=587) of ARNIs., Results: A total of 1089 consecutive patients underwent TEER for secondary MR. In the ARNI era, there was a reduction in left ventricle dilation (82mL vs 100mL, P=.025), and better function (35% vs 38%, P=.011). At 2 years of follow-up, mortality (10.6% vs 17.3%, P <.001) and heart failure readmissions (16.6% vs 27.8%, P <.001) were lower in the ARNI era, but not recurrent MR. In the ARNI era, 1- and 2-year mortality were similar irrespective of ARNI intake but patients on ARNIs had a lower risk of readmission+mortality at 2 years (OR, 0.369; 95%CI, 0.137-0.992; P=.048), better NYHA class, and lower recurrence of MR III-IV (1.9% vs 14.3%, P=.011)., Conclusions: Better patient selection for TEER has been achieved in the last few years with a parallel improvement in outcomes. The use of ARNIs was associated with a significant reduction in overall events, better NYHA class, and lower MR recurrence., (Copyright © 2022 Sociedad Española de Cardiología.

Background (1): Headache is a prevalent symptom experienced during ongoing SARS-CoV-2 infection, but also weeks after recovery. Whether cardio-pulmonary dysfunction contributes causally to headache persistence is unknown. Methods (2): We conducted a case-control analysis nested in a prospective cohort study. Individuals were recruited from August 2020 to December 2020. Patients were grouped according to the presence or absence of long-COVID headache for three months after COVID-19 resolution. We compared demographic data, clinical variables, cardio-pulmonary laboratory biomarkers, quality of life, and cardio-pulmonary function between groups. Results (3): A cohort of 70 COVID-19 patients was evaluated. Patients with headaches (n = 10; 14.3%) were more frequently female (100% vs. 58.4%; p = 0.011) and younger (46.9 ± 8.45 vs. 56.13 ± 12 years; p = 0.023). No between-group differences in laboratory analysis, resting echocardiography, cardio-pulmonary exercise test, or pulmonary function tests were observed. Conclusion (4): In this exploratory study, no significant differences in cardio-pulmonary dysfunction were observed between patients with and without long-COVID headache during mid-term follow-up.

Introduction and Objectives: Final position of the neo-commissures is uncontrolled during transcatheter aortic valve implantation (TAVI), potentially hindering coronary access and future procedures. We aimed to develop a standard method to achieve commissural alignment with the ACURATE neo valve., Methods: The relationship between native and TAVI neo-commissures was analyzed in 11 severe aortic stenosis patients undergoing TAVI. Based on computed tomography analysis, an in silico model was developed to predict final TAVI commissural posts position. A modified implantation technique, accurate commissural alignment (ACA) and a dedicated delivery system were developed. TAVI implants were tested in 3-dimensional (3D) printed models and in vivo. Commissural misalignment and coronary overlap (CO) were analyzed., Results: The in silico model accurately predicted final position of commissural posts irrespective of the implantation technique performed (correlation coefficient, 0.994; 95%CI, 0.989-0.998; P<.001). TAVI implant with patient-specific rotation was simulated in 3D printed models and in 9 patients. ACA-oriented TAVI implants presented adequate commissural alignment in vivo (mean commissural misalignment of 7.7 ±3.9°). None of the ACA oriented implants showed CO, whereas in silico conventional implants predicted CO in 6 of the 9 cases., Conclusions: Accurate commissural alignment of the ACURATE neo device is feasible by inserting the delivery system with a patient-specific rotation based on computed tomography analysis. This is a simple and reproducible method for commissural alignment that can be potentially used for all kinds of TAVI devices., (Copyright © 2021 Sociedad Española de Cardiología.

Objectives: The aims of this study were to determine the rate of noncentered coronary ostia and their risk for coronary overlap (CO) and to develop an improved orientation strategy for transcatheter aortic valve replacement (TAVR) devices taking into account anatomical cues to identify patients at risk for CO regardless of commissural alignment and compute an alternative, CO-free TAVR rotation angle for those patients., Background: Commissural alignment during TAVR reduces CO risk. However, eccentricity of coronary ostia from the center of the sinus of Valsalva may result in CO even after perfect alignment of TAVR commissures., Methods: Baseline computed tomography from TAVR candidates helped identify distance from commissures to the right coronary artery (RCA) and the left coronary artery (LCA). Then, for each case, a virtual valve was simulated with ideal commissural or coronary alignment, and the degree of CO was determined. On the basis of the potential BASILICA (bioprosthetic or native aortic scallop intentional laceration to prevent iatrogenic coronary artery obstruction) efficacy, 3 groups were defined: no risk for CO (>35° from neocommissure to coronary ostia), moderate risk (20°-35°), and severe risk (≤20°)., Results: Computed tomographic studies from 107 patients were included. After excluding 7 patients (poor quality or bicuspid valve), 100 patients were analyzed. The RCA showed greater eccentricity compared with the LCA (18.5° [IQR: 3.3°-12.8°] vs 6.5° [IQR: 3.3°-12.8°]; P < 0.001). The mean intercoronary angle was 140.0° ± 18.7° (95% CI: 136.3°-143.7°). Thirty-two patients had moderate to severe risk for CO (≤35°) despite ideal commissural alignment. Greater coronary eccentricity (cutoff for RCA, 24.5°; cutoff for LCA, 19°) and intercoronary angle >147.5° or <103° were associated with greater risk for moderate to severe CO despite commissural alignment (area under the curve: 0.97; 95% CI: 0.91-0.99). If optimal coronary alignment was simulated, this prevented severe CO in all cases and reduced moderate CO from 27% to 5% (P < 0.001)., Conclusions: One third of patients would have CO during TAVR-in-TAVR despite commissural alignment; a 6-fold decrease in this risk was achieved with optimized coronary alignment. Coronary eccentricity and intercoronary angle were the main predictors., Competing Interests: Funding Support and Author Disclosures This investigation received funding resources from the Spanish Society of Cardiology (SEC) with the grant number: SEC/FEC-INV-CLI 21/023.

Introduction and Objectives: Aortic self-expandable (SE) transcatheter aortic valve implantation (TAVI) devices are particularly useful for patients with aortic stenosis and small/tortuous vessels, small aortic annuli, or low coronary ostia. However, it is unclear whether the growing range of SE devices shows comparable hemodynamic and clinical outcomes. We aimed to determine the differential hemodynamic (residual valve area and regurgitation) and clinical outcomes of these devices in comparable scenarios., Methods: All patients were enrolled from 4 institutions and were managed with 4 different SE TAVI devices. Baseline and follow-up clinical data were collected and echocardiographic tests blindly and centrally analyzed. Patients were compared according to valve type and a 1:1 matched comparison was performed according to degree of calcification, aortic annulus dimensions, left ventricular ejection fraction, and body surface area., Results: In total, 514 patients were included (Evolut R/PRO, 217; ACURATE neo, 107; ALLEGRA, 102; Portico, 88). Surgical risk scores were comparable in the unmatched population. No differences were observed in the post-TAVI regurgitation rate and in in-hospital mortality (2.7%). The rate of pacemaker implantation at discharge was significantly different among devices (P=.049), with Portico showing the highest rate (23%) and ACURATE neo the lowest (9.5%); Evolut R/PRO and ALLEGRA had rates of 15.9% and 21.2%, respectively. The adjusted comparison showed worse residual TAVI gradients and aortic valve area with ACURATE neo vs ALLEGRA (P=.001) but the latter had higher risk of valve embolization and a tendency for more cerebrovascular events., Conclusions: A matched comparison of 4 SE TAVI devices showed no differences regarding residual aortic regurgitation and in-hospital mortality., (Copyright © 2020 Sociedad Española de Cardiología.

Objective: To evaluate the prognostic impact of urgent cardiac surgery on the prognosis of left-sided infective endocarditis (LSIE) and its relationship to the basal risk of the patient and to the surgical indication., Methods: 605 patients with LSIE and formal surgical indication were consecutively recruited between 2000 and 2020 among three tertiary centres: 405 underwent surgery during the active phase of the disease and 200 did not despite having indication. The prognostic impact of urgent surgery was evaluated by multivariable analysis and propensity score analysis. We studied the benefit of surgery according to baseline mortality risk defined by the ENDOVAL score and according to surgical indication., Results: Surgery is an independent predictor of survival in LSIE with surgical indication both by multivariable analysis (OR 0.260, 95% CI 0.162 to 0.416) and propensity score (mortality 40% vs 66%, p<0.001). Its greatest prognostic benefit is seen in patients at highest risk (predicted mortality 80%-100%: OR 0.08, 95% CI 0.021 to 0.299). The benefit of surgery is especially remarkable for uncontrolled infection indication (OR 0.385, 95% CI 0.194 to 0.765), even in combination with heart failure (OR 0.220, 95% CI 0.077 to 0.632)., Conclusions: Surgery during active LSIE seems to significantly reduce in-hospital mortality. The higher the risk, the higher the improvement in outcome., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021. No commercial re-use.

Background and Aims: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the sole causative agent of coronavirus infectious disease-19 (COVID-19)., Methods and Results: We performed a retrospective single-center study of consecutively admitted patients between March 1st and May 15th , 2020, with a definitive diagnosis of SARS-CoV-2 infection. The primary end-point was to evaluate the association of lipid markers with 30-days all-cause mortality in COVID-19. A total of 654 patients were enrolled, with an estimated 30-day mortality of 22.8% (149 patients). Non-survivors had lower total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-c) levels during the entire course of the disease. Both showed a significant inverse correlation with inflammatory markers and a positive correlation with lymphocyte count. In a multivariate analysis, LDL-c ≤ 69 mg/dl (hazard ratio [HR] 1.94; 95% confidence interval [CI] 1.14-3.31), C-reactive protein >88 mg/dl (HR 2.44; 95% CI, 1.41-4.23) and lymphopenia <1000 (HR 2.68; 95% CI, 1.91-3.78) at admission were independently associated with 30-day mortality. This association was maintained 7 days after admission. Survivors presented with complete normalization of their lipid profiles on short-term follow-up., Conclusion: Hypolipidemia in SARS-CoV-2 infection may be secondary to an immune-inflammatory response, with complete recovery in survivors. Low LDL-c serum levels are independently associated with higher 30-day mortality in COVID-19 patients., Competing Interests: Declaration of competing interest None., (Copyright © 2021 The Italian Diabetes Society, the Italian Society for the Study of Atherosclerosis, the Italian Society of Human Nutrition and the Department of Clinical Medicine and Surgery, Federico II University.

Introduction: Coronavirus disease 2019 (COVID-19) is a systemic disease characterized by a disproportionate inflammatory response in the acute phase. This study sought to identify clinical sequelae and their potential mechanism., Methods: We conducted a prospective single-center study (NCT04689490) of previously hospitalized COVID-19 patients with and without dyspnea during mid-term follow-up. An outpatient group was also evaluated. They underwent serial testing with a cardiopulmonary exercise test (CPET), transthoracic echocardiogram, pulmonary lung test, six-minute walking test, serum biomarker analysis, and quality of life questionaries., Results: Patients with dyspnea (n = 41, 58.6%), compared with asymptomatic patients (n = 29, 41.4%), had a higher proportion of females (73.2 vs. 51.7%; p = 0.065) with comparable age and prevalence of cardiovascular risk factors. There were no significant differences in the transthoracic echocardiogram and pulmonary function test. Patients who complained of persistent dyspnea had a significant decline in predicted peak VO 2 consumption (77.8 (64-92.5) vs. 99 (88-105); p < 0.00; p < 0.001), total distance in the six-minute walking test (535 (467-600) vs. 611 (550-650) meters; p = 0.001), and quality of life (KCCQ-23 60.1 ± 18.6 vs. 82.8 ± 11.3; p < 0.001). Additionally, abnormalities in CPET were suggestive of an impaired ventilatory efficiency (VE/VC O2 slope 32 (28.1-37.4) vs. 29.4 (26.9-31.4); p = 0.022) and high PET CO2 (34.5 (32-39) vs. 38 (36-40); p = 0.025)., Interpretation: In this study, >50% of COVID-19 survivors present a symptomatic functional impairment irrespective of age or prior hospitalization. Our findings suggest a potential ventilation/perfusion mismatch or hyperventilation syndrome.

Introduction and Objectives: To determine whether renin-angiotensin system inhibitor (RASi) prescription is associated with better outcomes after transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR)., Methods: All comparative studies of RASi vs no RASi prescription in patients undergoing TAVI/SAVR were gathered from PubMed, Web of Science, and Google Scholar through August, 2019. We extracted hazard ratios (HRs) with their confidence intervals (CIs) for mortality from each study and combined study-specific estimates using inverse variance-weighted averages of logarithmic HRs in the random effects model., Results: We identified 6 eligible studies with a total of 21 390 patients (TAVI: 17 846; SAVR: 3544) and included them in the present meta-analysis. The 6 studies were observational comparative studies (including 3 propensity score matched and 3 cohort studies) of RASi vs no RASi prescription. The analysis demonstrated that RASi prescription was associated with significantly lower mortality in the whole group of patients undergoing aortic valve intervention (HR, 0.64; 95%CI, 0.47-0.88; P <.001). However, subgroup analysis suggested differences according to the selected therapy, with TAVI showing better mortality rates in the RASi group (HR, 0.67; 95%CI, 0.49-0.93) but not in the SAVR group (HR, 0.61; 95%CI, 0.29-1.30). No funnel plot asymmetry was identified, suggesting minimum publication bias. Sensitivity analyses sequentially eliminating dissimilar studies did not substantially alter the primary result favoring RASI prescription., Conclusions: These findings suggest a mortality benefit of RASi in patients with AS treated with aortic valve replacement that might be particularly relevant following TAVI. Future randomized studies are warranted to confirm this relevant finding., (Copyright © 2020 Sociedad Española de Cardiología. Published by Elsevier España, S.L.U. All rights reserved.)

Introduction: Despite of the wide evidence of use fractional flow reserve (FFR), isolated angiography evaluation is still the main tool to indicate percutaneous coronary intervention. Quantitative flow ratio (QFR) is a new functional index to assess functional significance. Recently, few studies have showed the capacity of QFR to predict significance stenosis. The aim of this research has been to describe the evidence of QFR in this clinical setting, to analyze the global diagnosis accuracy of QFR versus FFR and to compare the difference in feasibility between retrospective and prospective analysis., Methods and Results: Systematic review of literature was performed. Eligible studies for the meta-analysis were considered those directly evaluating de QFR versus FFR. Pooled values of diagnosis test and summary receiver operator curve were calculated. Main causes of not-perform QFR analysis according to study design were also evaluated. Sixteen studies were included. Good correlation and agreement were showed. Global sensibility, specificity, PPV, and NPV were 0.84, 0.89, 0.80, and 0.92, respectively. Then, 18% of evaluated vessels could not be analyzed. Significant differences were found in the percentage of discarded vessels and the cause of nonperformed analysis between retrospective or prospective analysis., Conclusions: Excellent correlation and agreement between QFR and FFR was demonstrated. QFR assessment could be improved by its prospective analysis with a dedicated protocol., (© 2020 Wiley Periodicals, Inc.)

Objectives: This study aimed to evaluate the safety and mid-term efficacy of transcatheter aortic valve replacement (TAVR) in the setting of aortic valve (AV) infective endocarditis (IE) with residual lesion despite successful antibiotic treatment., Background: Patients with AV-IE presenting residual lesion despite successful antibiotic treatment are often rejected for cardiac surgery due to high-risk. The use of TAVR following IE is not recommended., Methods: This was a multicenter retrospective study across 10 centers, gathering baseline, in-hospital, and 1-year follow-up characteristics of patients with healed AV-IE treated with TAVR. Matched comparison according to sex, EuroSCORE, chronic kidney disease, left ventricular function, prosthesis type, and valve-in-valve procedure was performed with a cohort of patients free of prior IE treated with TAVR (46 pairs)., Results: Among 2,920 patients treated with TAVR, 54 (1.8%) presented with prior AV-IE with residual valvular lesion and healed infection. They had a higher rate of multivalvular disease and greater surgical risk scores. A previous valvular prosthesis was more frequent than a native valve (50% vs. 7.5%; p < 0.001). The in-hospital and 1-year mortality rates were 5.6% and 11.1%, respectively, comparable to the control cohort. After matching, the 1-year III to IV aortic regurgitation rate was 27.9% (vs. 10%; p = 0.08) and was independently associated with higher mortality. There was only 1 case of IE relapse (1.8%); however, 18% of patients were complicated with sepsis, and 43% were readmitted due to heart failure., Conclusions: TAVR is a safe therapeutic alternative for residual valvular lesion after successfully healed AV-IE. At 1-year follow-up, the risk of IE relapse was low and mortality rate did not differ from TAVR patients free of prior IE, but one-fourth presented with significant aortic regurgitation and >50% required re-admission., (Copyright © 2020 American College of Cardiology Foundation.

Background: Coronavirus disease-2019 (COVID-19) is caused by severe acute respiratory-syndrome coronavirus-2 that interfaces with the renin-angiotensin-aldosterone system (RAAS) through angiotensin-converting enzyme 2. This interaction has been proposed as a potential risk factor in patients treated with RAAS inhibitors., Objectives: This study analyzed whether RAAS inhibitors modify the risk for COVID-19., Methods: The RASTAVI (Renin-Angiotensin System Blockade Benefits in Clinical Evolution and Ventricular Remodeling After Transcatheter Aortic Valve Implantation) trial is an ongoing randomized clinical trial randomly allocating subjects to ramipril or control groups after successful transcatheter aortic valve replacement at 14 centers in Spain. A non-pre-specified interim analysis was performed to evaluate ramipril's impact on COVID-19 risk in this vulnerable population., Results: As of April 1, 2020, 102 patients (50 in the ramipril group and 52 in the control group) were included in the trial. Mean age was 82.3 ± 6.1 years, 56.9% of the participants were male. Median time of ramipril treatment was 6 months (interquartile range: 2.9 to 11.4 months). Eleven patients (10.8%) have been diagnosed with COVID-19 (6 in control group and 5 receiving ramipril; hazard ratio: 1.150; 95% confidence interval: 0.351 to 3.768). The risk of COVID-19 was increased in older patients (p = 0.019) and those with atrial fibrillation (p = 0.066), lower hematocrit (p = 0.084), and more comorbidities according to Society of Thoracic Surgeons score (p = 0.065). Admission and oxygen supply was required in 4.9% of patients (2 in the ramipril group and 3 in the control group), and 4 of them died (2 in each randomized group). A higher body mass index was the only factor increasing the mortality rate (p = 0.039)., Conclusions: In a high-risk population of older patients with cardiovascular disease, randomization to ramipril had no impact on the incidence or severity of COVID-19. This analysis supports the maintenance of RAAS inhibitor treatment during the COVID-19 crisis.

Background: Atrial septal defect (ASD) is one of the most common congenital heart diseases. Percutaneous closure is the preferred treatment, but certain complications remain a concern. The most common devices are AMPLATZER™ (ASO) (St. Jude Medical, St. Paul, MN, USA) and Figulla Flex® septal occluders (FSO) (Occlutech GmbH, Jena, Germany). The present study aimed to assess main differences in outcomes., Methods: A systematic search in Pubmed and Google scholarship was performed by two independent reviewers for any study comparing ASO and FSO. Searched terms were "Figulla", "Amplatzer", and "atrial septal defect". A random-effects model was used., Results: A total of 11 studies including 1770 patients (897 ASO; 873 FSO) were gathered. Baseline clinical and echocardiographic characteristics were comparable although septal aneurysm was more often reported in patients treated with ASO (32% vs. 25%; p = 0.061). Success rate (94% vs. 95%; OR: 0.81; 95% CI: 0.38-1.71; p = 0.58) and peri-procedural complications were comparable. Procedures were shorter, requiring less fluoroscopy time with an FSO device (OR: 0.59; 95% CI: 0.20-0.97; p = 0.003). Although the global rate of complications in long-term was similar, the ASO device was associated with a higher rate of supraventricular arrhythmias (14.7% vs. 7.8%, p = 0.009)., Conclusions: Percutaneous closure of ASD is a safe and effective, irrespective of the type of device. No differences exist regarding procedural success between the ASO and FSO devices but the last was associated to shorter procedure time, less radiation, and lower rate of supraventricular arrhythmias in follow-up. Late cardiac perforation did not occur and death in the follow-up was exceptional.

Background: Several studies have demonstrated the benefits of transcatheter aortic valve replacement (TAVR) in patients with aortic stenosis, but the presence of persistent fibrosis and myocardial hypertrophy has been related to worse prognosis., Objectives: The aim of this study was to explore the potential benefits of renin-angiotensin system (RAS) inhibitors on left ventricular remodeling and major clinical outcomes following successful transcatheter aortic valve replacement (TAVR)., Methods: Patients from 10 institutions with severe aortic stenosis who underwent TAVR between August 2007 and August 2017 were included. All baseline data were prospectively recorded, and pre-specified follow-up was performed. Doses and types of RAS inhibitors at discharge were recorded, and matched comparison according to their prescription at discharge was performed., Results: A total of 2,785 patients were included. Patients treated with RAS inhibitors (n = 1,622) presented similar surgical risk scores but a higher rate of all cardiovascular risk factors, coronary disease, and myocardial infarction. After adjustment for these baseline differences, reduction of left ventricular volumes and hypertrophy was greater and cardiovascular mortality at 3-year follow-up was lower (odds ratio: 0.59; 95% confidence interval: 0.41 to 0.87; p = 0.007) in patients treated with RAS inhibitors. Moreover, RAS inhibitors demonstrated a global cardiovascular protective effect with significantly lower rates of new-onset atrial fibrillation, cerebrovascular events, and readmissions., Conclusions: Post-TAVR RAS inhibitors are associated with lower cardiac mortality at 3-year follow-up and offer a global cardiovascular protective effect that might be partially explained by a positive left ventricular remodeling. An ongoing randomized trial will help confirm these hypothesis-generating findings.

Introduction and Objectives: Many patients undergoing transcatheter aortic valve implantation (TAVI) have concomitant mitral regurgitation (MR) of moderate grade or less. The impact of coexistent tricuspid regurgitation (TR) remains to be determined. We sought to analyze the impact of moderate vs none-to-mild MR and its trend after TAVI, as well as the impact of concomitant TR and its interaction with MR., Methods: Multicenter retrospective study of 813 TAVI patients treated through the transfemoral approach with MR ≤ 2 between 2007 and 2015., Results: The mean age was 81 ± 7 years and the mean Society of Thoracic Surgeons score was 6.9% ± 5.1%. Moderate MR was present in 37.3% of the patients, with similar in-hospital outcomes and 6-month follow-up mortality to those with MR < 2 (11.9% vs 9.4%; P = .257). However, they experienced more rehospitalizations and worse New York Heart Association class (P = .008 and .001, respectively). Few patients (3.8%) showed an increase in the MR grade to > 2 post-TAVI. The presence of concomitant moderate/severe TR was associated with in-hospital and follow-up mortality rates of 13% and 34.1%, respectively, regardless of MR grade. Moderate-severe TR was independently associated with mortality (HR, 18.4; 95%CI, 10.2-33.3; P < .001)., Conclusions: The presence of moderate MR seemed not to impact short- and mid-term mortality post-TAVI, but was associated with more rehospitalizations. The presence of moderate or severe TR was associated with higher mortality. This suggests that a thorough evaluation of the mechanisms underlying concomitant mitral and tricuspid valve regurgitation should be performed to determine the best strategy for avoiding TAVI-related futility., (Copyright © 2018 Sociedad Española de Cardiología.
