Abstract
Background We examined the frequency and risk factors associated with readmission after left atrial appendage closure (LAAC) in patients with and without previous ischemic stroke and/or transient ischemic attack (TIA). Methods Hospitalizations for LAAC were identified from the US National Readmission Database, 2016-2018. The primary outcome was the first unplanned readmission after LAAC, with readmission times stratified into those occurring within 0 to 30 days vs within 31 to 180 days. Patients were stratified based on the history of previous stroke and/or TIA. Results Of 12,901 discharges after LAAC, 28% had previous stroke and/or TIA, and 8.2% had a readmission within 30 days while 18% had a readmission within 31 to 180 days. The rates of in-hospital complications and readmissions at both periods were not significantly different between individuals with vs without previous stroke and/or TIA. Cardiac causes accounted for 28% of readmissions within 30 days and 32% of those within 31 to 180 days, and congestive failure, bleeding, and infections were the most common readmission diagnoses. New stroke and/or TIA accounted for 4% and 6% of the total noncardiac readmissions within 30 days and 31 to 180 days, respectively, and the incidence was higher among those with previous stroke and/or TIA. Female sex and index hospitalization length of stay (LOS) > 1 day were factors independently associated with readmission within 30 days, whereas LOS, diabetes, renal disease, chronic obstructive pulmonary disease, and anemia were among the factors associated with readmissions within 31 to 180 days. Conclusions Unplanned rehospitalizations were common after LAAC and had similar frequency for patients with vs without previous ischemic stroke and/or TIA. Female sex and index hospitalization LOS > 1 day were among the strongest factors that were independently associated with readmission within 30 days.

Abstract
Background Transcatheter aortic valve intervention (TAVI) can lead to the embolization of debris. Capturing the debris by cerebral embolic protection (CEP) devices may reduce the risk of stroke. New evidence has allowed us to examine the effects of CEP in patients undergoing TAVI. We aimed to assess the effects of CEP overall and stratified by the device used (SENTINEL or TriGuard) and the surgical risk of the patients. Methods We selected randomized controlled trials using electronic databases through September 17, 2022. We estimated random-effects risk ratios (RR) with (95% confidence interval) and calculated absolute risk differences at 30 days across baseline surgical risks derived from the TAVI trials for any stroke (disabling and nondisabling) and all-cause mortality. Results Among 6 trials (n = 3921), CEP vs. control did not reduce any stroke [RR: 0.95 (0.50-1.81)], disabling [RR: 0.75 (0.18-3.16)] or nondisabling [RR: 0.99 (0.65-1.49)] strokes, or all-cause mortality [RR: 1.23 (0.55-2.77)]. However, when analyzed by device, SENTINEL reduced disabling stroke [RR: 0.46 (0.22-0.95)], translating into 6 fewer per 1000 in high-risk, 3 fewer per 1000 in intermediate-risk, and 1 fewer per 1000 in low surgical-risk patients. CEP vs. control did not reduce the risk of any bleeding [RR: 1.03 (0.44-2.40)], major vascular complications [RR: 1.41 (0.57-3.48)], or acute kidney injury [RR: 1.36 (0.57-3.28)]. Conclusions This updated meta-analysis showed that SENTINEL CEP might reduce disabling stroke in patients undergoing TAVI. Patients with high and intermediate surgical risks were most likely to derive benefits.

Abstract
Prevention of stroke represents a goal of primary importance in health systems due to its associated morbidity and mortality. As several patient groups with increased stroke rates have been identified, multiple approaches have been developed and implemented: oral anticoagulation (OAC) for patients with atrial fibrillation, surgical and percutaneous revascularisation in patients with carotid disease, device closure for patients with patent foramen ovale, and now, left atrial appendage occlusion (LAAO) for selected patients with non-valvular atrial fibrillation (NVAF). The latter group of patients are the focus of this review which evaluates the pathophysiology, selection of patients, procedural performance, outcomes of treatment both during and post-procedure, adjunctive therapy, complications, and longer-term outcomes.

Abstract
BACKGROUND Percutaneous balloon mitral valvuloplasty (PBMV) is primarily performed for rheumatic mitral stenosis (MS). Therefore, limited data exist on PBMV in countries with a low incidence of rheumatic disease. METHODS Using the Nationwide Readmission Database, we examined trends in in-hospital mortality and 30-day readmission among patients who received PBMV for rheumatic and non-rheumatic MS. We also examined the change in 90-day hospitalization rate before vs. after PBMV. RESULTS Between 2016 and 2019, there were 1109 hospitalizations in which patients received PBMV for rheumatic (n= 955, 86.1%) vs non-rheumatic MS (n=154, 13.9%). The all-cause in-hospital mortality for rheumatic and non-rheumatic MS did not change over time (0.9% → 2.0%, p=0.94, and 5.9% → 9.5%, p=0.09 respectively). Similarly, the 30-day readmission for patients with rheumatic and non-rheumatic MS did not change over time (12.4% → 9.9%, p=0.26, and 4.4% → 10.5%, p=0.30, respectively). The 90-day all-cause hospitalization rate remained the same before vs after PBMV for rheumatic and non-rheumatic MS (25.5% → 21.8%; p=0.14, and 24.0% → 33.7%; p=0.19, respectively). CONCLUSIONS Although no statistically significant change was noted over time for trends in in-hospital mortality, 30-day readmission, or even in the change in 90-day all-cause hospitalizations before and after PBMV for both types of MS, among those with non-rheumatic MS, there was a signal of an increase in the in-hospital mortality, and 30-day readmission, even more, there was 29% relative increase in 90-day hospitalizations after PBMV. Future studies are needed to examine the role of PBMV in patients with non-rheumatic MS.

Abstract
The importance of the left atrial appendage (LAA) as the source of thromboembolism including stroke in patients with nonvalvular atrial fibrillation is well documented, with more than 90% of ischemic strokes related to a LAA thrombus. Although oral anticoagulation has been the standard of care, approximately 50% to 60% of patients either have contraindications to oral anticoagulation or do not continue the medication beyond the first year. This led to the development of local site-specific therapy to occlude the LAA by either surgical or transcatheter means. Despite marked advancements, incomplete LAA closure with surgical and transcatheter approaches remains frequent. The etiology of incomplete LAA closure and its clinical implications remain unclear. Multiple strategies are in development including changes in deployment techniques, a new device design, and alternative approaches to leak closure.

Abstract
Thrombus formation on intracardiac devices remains a subject of importance, with rates in the 2-5% range. Device-related thrombus (DRT) following left atrial appendage occlusion is an area of particular concern considering its association with embolic events. DRT continues to present numerous questions, including the optimal definition, incidence, risk factors, monitoring, therapy, and clinical outcomes - all subjects of ongoing assessment. Herein, we discuss these considerations, building upon the relevant historical context and pathophysiologic insights while discussing the future considerations in this rapidly evolving field.

Abstract
Predicting potential complications after aortic valve replacement (AVR) is a crucial task that would help pre-planning procedures. The goal of this work is to generate data-driven models based on logistic regression, where the probability of developing transvalvular pressure gradient (DP) that exceeds 20 mmHg under different physiological conditions can be estimated without running extensive experimental or computational methods. The hemodynamic assessment of a 26 mm SAPIEN 3 transcatheter aortic valve and a 25 mm Magna Ease surgical aortic valve was performed under pulsatile conditions of a large range of systolic blood pressures (SBP; 100-180 mmHg), diastolic blood pressures (DBP; 40-100 mmHg), and heart rates of 60, 90 and 120 bpm. Logistic regression modeling was used to generate a predictive model for the probability of having a DP > 20 mmHg for both valves under different conditions. Experiments on different pressure conditions were conducted to compare the probabilities of the generated model and those obtained experimentally. To test the accuracy of the predictive model, the receiver operation characteristics curves were generated, and the areas under the curve (AUC) were calculated. The probabilistic predictive model of DP > 20 mmHg was generated with parameters specific to each valve. The AUC obtained for the SAPIEN 3 DP model was 0.9465 and that for Magna Ease was 0.9054 indicating a high model accuracy. Agreement between the DP probabilities obtained between experiments and predictive model was found. This model is a first step towards developing a larger statistical and data-driven model that can inform on certain valves reliability during AVR pre-procedural planning.

Background/Introduction: Transesophageal echocardiography (TEE) has long provided excellent diagnostic imaging of left-sided valvular pathology with an excellent safety profile; however, recent data has suggested an increased risk of injury related to TEE guidance.
Purpose
This study aims to evaluate the incidence and nature of TEE-related oropharyngeal or esophageal complications in patients undergoing TEE-guided structural heart procedures and identify associated risk factors.
Methods
We reviewed consecutive patients undergoing TEE-guided structural heart procedures from 2005-2020. All procedures were performed under general anesthesia. TEE-related oropharyngeal or esophageal complications were defined as those occurring within 30 days of the procedure resulting in i) persistent dysphagia, odynophagia, or upper gastrointestinal bleeding requiring prolonged endotracheal intubation, therapeutic endoscopic or surgical intervention, or diagnostic imaging that demonstrated oropharyngeal or esophageal injury. ii) upper gastrointestinal bleed requiring transfusion, hemodynamic compromise warranting mechanical or pharmacologic support; or iii) oropharyngeal or esophageal complications leading to death. For multivariate analysis, all variables with a p < 0.15 at univariate analysis were included in the model.
Results
Among 1229 adult patients undergoing TEE-guided structural heart procedures between 2005-2020, 274 underwent a transcatheter aortic valve replacement (TAVR) with the remaining 955 undergoing either mitral valve transcatheter edge-to-edge repair (mTEER, n = 278), mitral paravalvular leak closure (PVLC, n = 354), mitral valve-in-valve replacement (VIV, n = 41), or left atrial appendage closure (LAAO, n = 282). Of these, 6 (0.5 %) had TEE-related complications; 0% TAVR, 0% VIV, 0.36% LAAO, 0.28% PVLC, 1.41% mTEER (p = 0.14). Of the six patients with complications 3 required at least one day of prolonged tracheal intubation and one a blood transfusion. None required surgical repair. Factors associated with increased complication risk (Table) included a prior history of gastrointestinal bleed (Odds ratio 5.44 [0.98-30.04; p = 0.05]) and longer procedural time (OR per 30 min 1.15 [1.01-1.31, p = 0.03]). Patients undergoing mTEER had an increased risk of complication (OR 6.76 [1.23-37.1 p = 0.03]) and longer procedural time (OR per 30 mins 1.15[1.01-1.31, p = 0.04]) compared to other all other procedures.
Conclusion(s): In a large series of patients undergoing cardiac structural interventions under general anesthesia with TEE-guidance, rates of TEE-induced injury were low. Risk of oropharyngeal or esophageal complications was increased with longer procedure times, prior gastrointestinal bleeding history, increased age, increased pre-procedural creatinine, procedural type being mTEER and in male patients, lower height.

Abstract
OBJECTIVE Our objective was to evaluate the impact of various blood pressures (BPs) on coronary perfusion and valvular hemodynamics following aortic valve replacement (AVR). BACKGROUND Lower systolic and diastolic (SBP/DBP) pressures from the recommended optimal target range of SBP < 120-130 mmHg and DBP < 80 mmHg after AVR have been independently associated with increased cardiovascular and all-cause mortality. METHODS The hemodynamic assessment of a 26 mm SAPIEN 3 transcatheter aortic valve (TAV), 29 mm Evolut R TAV, and 25 mm Magna Ease surgical aortic valve (SAV) was performed in a pulsed left heart simulator with varying SBP, DBP, and heart rate (HR) conditions (60 and 120 bpm) at 5 L/min cardiac output (CO). Average coronary flow (CF), effective orifice areas (EOAs), and valvulo-arterial impedance (Zva) were calculated. RESULTS At HR of 60 bpm, at SBP < 120 mmHg and DBP < 60 mmHg, CF decreased below the physiological lower limit with several different valves. Zva and EOA were found to increase and decrease respectively with increasing SBP and DBP. The same results were found with an HR of 120 bpm. The trends of CF variation with BP were similar in all valves however the drop below the lower physiological CF limit was valve dependent. CONCLUSION In a controlled in vitro system, with different aortic valve prostheses in place, CF decreased below the physiologic minimum when SBP and DBP were in the range targeted by blood pressure guidelines. Combined with recent observations from patients treated with AVR, these findings underscore the need for additional studies to identify the optimal BP in patients treated with AVR for AS.

Abstract
BACKGROUND Aging is associated with progressive loss of muscle mass, as well as replacement of muscle with fat and fibrous tissue. We studied the contribution of muscle fat content, a surrogate marker of biological aging, to frailty and Length of Hospital Stay (LOS) following Transcatheter Aortic Valve Replacement (TAVR). METHODS We evaluated 415 patients who underwent TAVR from February 2012 to December 2016 at Mayo Clinic, MN, USA. Densities between -190 to -30 Hounsfield Units within the abdominal muscle area were determined as muscle fat. Muscle Fat Index (MFI) was defined as muscle fat mass divided by height squared. LOS was considered as the primary outcome. Stepwise multivariable linear regression was used to identify the predictors of LOS. RESULTS Mean age ± SD of the study population was 81.2 ± 9.6 years and 58.07% were male. Seventy-two patients (17.35%) had frailty. Median (IQR) LOS was 4 (3-6) days. MFI was higher in patients with frailty (median (IQR); 18.1 [13.8-24.2] vs 14.4 [10.6-18.7], p < 0.001) and was positively correlated with LOS (r = 0.129, p = 0.009). In multivariable analysis of predictors of LOS, MFI (β = 0.06, p = 0.022), pre-TAVR atrial fibrillation/flutter (β = 0.5, p = 0.015), and post-TAVR complications (β = 0.91, p < 0.001) were directly, and femoral access route (β = -1.13, p < 0.001) and pre-TAVR hemoglobin (β = -0.35, p = 0.002) were inversely associated with LOS. CONCLUSIONS MFI can be determined from pre-TAVR CT scans and is a novel predictor of LOS following TAVR. This objective indicator can potentially be used in a pre-TAVR clinic to plan for rehabilitation programs in selected patients.

Abstract
The aortic valve is a highly dynamic structure characterized by a transvalvular flow that is unsteady, pulsatile, and characterized by episodes of forward and reverse flow patterns. Calcific aortic valve disease (CAVD) resulting in compromised valve function and increased pressure overload on the ventricle potentially leading to heart failure if untreated, is the most predominant valve disease. CAVD is a multi-factorial disease involving molecular, tissue and mechanical interactions. In this review, we aim at recapitulating the biomechanical loads on the aortic valve, summarizing the current and most recent research in the field in vitro, in-silico, and in vivo, and offering a clinical perspective on current strategies adopted to mitigate or approach CAVD.

Abstract
BACKGROUND The association between socioeconomic status (SES), sex, race / ethnicity and outcomes during hospitalization for heart failure (HF) has not previously been investigated. METHODS AND RESULTS We analyzed HF hospitalizations in the United States National Inpatient Sample between 2015 and 2017. Using a hierarchical, multivariable Poisson regression model to adjust for hospital- and patient-level factors, we assessed the association between SES, sex, and race / ethnicity and all-cause in-hospital mortality. We estimated the direct costs (USD) across SES groups. Among 4,287,478 HF hospitalizations, 40.8% were in high SES, 48.7% in female, and 70.0% in White patients. Relative to these comparators, low SES (homelessness or lowest quartile of median neighborhood income) (relative risk [RR] 1.02, 95% confidence interval [CI] 1.00-1.05) and male sex (RR 1.09, 95% CI 1.07-1.11) were associated with increased risk, whereas Black (RR 0.79, 95% CI 0.76-0.81) and Hispanic (RR 0.90, 95% CI 0.86-0.93) race / ethnicity were associated with a decreased risk of in-hospital mortality (5.1% of all hospitalizations). There were significant interactions between race / ethnicity and both, SES (P < .01) and sex (P = .04), such that racial/ethnic differences in outcome were more pronounced in low SES groups and in male patients. The median direct cost of admission was lower in low vs high SES groups ($9324.60 vs $10,940.40), female vs male patients ($9866.60 vs $10,217.10), and Black vs White patients ($9077.20 vs $10,019.80). The median costs increased with SES in all demographic groups primarily related to greater procedural utilization. CONCLUSIONS SES, sex, and race / ethnicity were independently associated with in-hospital mortality during HF hospitalization, highlighting possible care disparities. Racial/ethnic differences in outcome were more pronounced in low SES groups and in male patients.

Abstract
BACKGROUND Doppler mean gradient (MG) may underestimate aortic stenosis (AS) severity when obtained during atrial fibrillation (AF) because of lower forward flow compared with sinus rhythm (SR). Whether AS is more advanced at the time of referral for aortic valve intervention in AF compared with SR is unknown. The aim of this study was to examine flow-independent computed tomographic aortic valve calcium scores (AVCS) and their concordance to MG in AF versus SR in patients undergoing transcatheter aortic valve replacement (TAVR). METHODS Patients who underwent TAVR from 2016 to 2020 for native valve severe AS with left ventricular ejection fraction ≥ 50% were identified from an institutional TAVR database. MGs during AF and SR in high-gradient AS (HGAS) and low-gradient AS (LGAS) were compared with AVCS (AVCS/MG ratio). AVCS were obtained within 90 days of pre-TAVR echocardiography. RESULTS Six hundred thirty-three patients were included; median age was 82 years (interquartile range [IQR], 76-86 years), and 46% were women. AF was present in 109 (17%) and SR in 524 (83%) patients during echocardiography. Aortic valve area index was slightly smaller in AF versus SR (0.43 cm2/m2 [IQR, 0.39-0.47 cm2/m2] vs 0.46 cm2/m2 [IQR, 0.41-0.51 cm2/m2], P = .0003). Stroke volume index, transaortic flow rate, and MG were lower in AF (P < .0001 for all). AVCS were higher in men with AF compared with SR (3,510 Agatston units [AU] [IQR, 2,803-4,030 AU] vs 2,722 AU [IQR, 2,180-3,467 AU], P < .0001) in HGAS but not in LGAS. AVCS were not different in women with AF versus SR. Overall AVCS/MG ratios were higher in AF versus SR in HGAS and LGAS (P < .03 for all), except in women with LGAS. CONCLUSIONS AVCS were higher than expected by MG in AF compared with SR. The very high AVCS in men with AF and HGAS at the time of TAVR suggests late diagnosis of severe AS because of underestimated AS severity during progressive AS and/or late referral to TAVR. Additional studies are needed to examine the extent to which echocardiography may be underestimating AS severity in AF.

Abstract
OBJECTIVES The aim of this study was to determine the safety of eliminating the pre-discharge transthoracic echocardiogram (TTE) on 30-day outcomes in patients undergoing transcatheter aortic valve replacement (TAVR). BACKGROUND TTE is utilized before, during, and after TAVR. Post-procedural, pre-discharge TTE assists in assessment of prosthesis function and detection of clinically significant paravalvular leak (PVL) after TAVR. METHODS Patients who underwent TAVR at Mayo Clinic from July 2018 to July 2019 were included in a prospective institutional registry. Patients undergoing TAVR prior to February 2019 received a pre-discharge TTE, while those undergoing TAVR after February 2019 did not. Both cohorts were evaluated with TTE at 30 days post-TAVR. RESULTS A total of 330 consecutive patients were included. Of these, 160 patients (age 81.1 ± 7.6) had routine pre-discharge TTE, while 170 patients (age 78.9 ± 7.5) were dismissed without routine pre-discharge TTE. Mortality at 30 days was similar between the two groups (0% and 1.2%, respectively). One episode of PVL requiring intervention (0.6%) occurred in the pre-discharge TTE group and none in the group without pre-discharge TTE at 30-day follow-up. There was a similar incidence of total composite primary and secondary adverse events between the cohort receiving a pre-discharge TTE and those without (28.1% vs. 25.3%, P = 0.56) at 30 days. The most common event was need for permanent pacemaker or ICD implantation in both groups (13.1% vs. 11.8%, P = 0.71). CONCLUSIONS Elimination of the pre-discharge TTE is safe and associated with comparable 30-day outcomes to routine pre-discharge TTE. These findings have implication for TAVR practice cost-efficiency and health care utilization.

Abstract
BACKGROUND Surgical intervention in patients with native mitral disease due to severe mitral annular calcification (MAC) carries significant risk. Transcatheter mitral valve replacement (TMVR) using balloon-expandable aortic transcatheter heart valve (THV) in MAC had emerged as alternative treatment. OBJECTIVES We aim to study the temporal change in clinical outcomes of the procedure at a single center. METHODS We retrospectively studied 23 patients who underwent TMVR in MAC at Mayo Clinic from January, 14, 2014 to March, 15, 2019. Cases were divided into early (n = 11) and late (n = 12) experience. The primary end point was 30-day all-cause mortality. The secondary end points were immediate technical success, 30-day procedural success, and 1-year all-cause mortality. RESULTS Mean age of patients was 75.2 ± 8.9 years and 17 (74.0%) were female. Median STS score for 30-day mortality was 8 (Interquartile range 4.3-13.4) for the entire population. Immediate technical success was achieved in 21 out of 23 patients (two failures in the early experience were related to tamponade and procedural death). Thirty-day procedural success was higher in the late experience (10 out of 12 patients) compared to early experience (5 out of 11 patients, p = .06). Four deaths in the first 30-days were observed in the early experience while all patients survived to hospital discharge in the late experience (p = .01). CONCLUSIONS Procedural success and 30-day survival of transcatheter mitral valve replacement in severe mitral annular calcification procedure using balloon-expandable aortic prosthesis had improved over the years. This is likely attributed to significant advancement in procedural planning, valve design, and techniques.

Abstract
OBJECTIVES The aim of this study was to evaluate the outcome of transcatheter mitral valve repair (TMVr) in patients with cardiogenic shock and significant mitral regurgitation (MR). BACKGROUND Patients in cardiogenic shock with severe MR have a poor prognosis in the setting of conventional medical therapy. Because of its favorable safety profile, TMVr is being increasingly used as an acute therapy in this population, though its efficacy remains unknown. METHODS A multicenter, collaborative, patient-level analysis was conducted. Patients with cardiogenic shock and moderate to severe (3+) or severe (4+) MR who were not surgical candidates were treated with TMVr. The primary outcome was in-hospital mortality. Secondary outcomes included 90-day mortality, heart failure (HF) hospitalization, and the combined event rate of 90-day mortality and HF hospitalization following dichotomization by TMVr device success. RESULTS Between January 2011 and February 2019, 141 patients across 14 institutions met the inclusion criteria. In-hospital mortality occurred in 22 patients (15.6%), at 90 days in 38 patients (29.5%), and at one year in 55 patients (42.6%). Median length of hospital stay following TMVr was 10 days (interquartile range: 6 to 20 days). HF hospitalization occurred in 26 patients (18.4%) at a median of 73 days (interquartile range: 26 to 546 days). When stratified by TMVr procedural results, successful TMVr reduced rates of in-hospital mortality (hazard ratio [HR]: 0.36; 95% confidence interval [CI]: 0.13 to 0.98; p = 0.04), 90-day mortality (HR: 0.36; 95% CI: 0.16 to 0.78; p = 0.01), and the composite of 90-day mortality and HF hospitalization (HR: 0.41; 95% CI: 0.19 to 0.90; p = 0.03). CONCLUSIONS TMVr may improve short- and intermediate-term mortality in high-risk patients with cardiogenic shock and moderate to severe MR. Randomized studies are needed to definitively establish MR as a therapeutic target in patients with cardiogenic shock.

Abstract
OBJECTIVES The aim of this study was to assess the 30 day incidence of paravalvular leak (PVL) and need for aortic valve reintervention of a fourth generation balloon expandable transcatheter valve with enhanced skirt (4G-BEV) (SAPIEN 3 Ultra) compared with a third generation balloon expandable transcatheter valve (3G-BEV) (SAPIEN 3). BACKGROUND The incidence of PVL has steadily declined with iterative improvements in transcatheter aortic valve replacement (TAVR) technology and implantation strategies. METHODS Patients who underwent TAVR at Mayo Clinic from 7/2018 to 7/2019 were included in a prospective institutional registry. 4G-BEV has been utilized since 2/2019, and, after this date, 3G-BEV and 4G-BEV were simultaneously used. 4G-BEV had three sizes (20, 23, and 26 mm) while 3G-BEV included four sizes (20, 23, 26, and 29 mm). Both cohorts were evaluated at 30 days post-TAVR with a transthoracic echocardiogram to assess for PVL. RESULTS A total of 260 consecutive patients were included. Of these, 101 patients received a 4G-BEV and 159 patients received a 3G-BEV. There were more females (p = .0005) and a lower aortic valve calcium score (p = .02) in the 4G-BEV cohort at baseline. Age, STS risk score, NYHA Class, and aortic valve mean gradient did not differ between groups. 4G-BEV was associated with a lower incidence of mild PVL (10.8 vs. 36.5%; p < .0001) and moderate PVL (0 vs. 5.8%) compared to the 3G-BEV at 30 days. There was no association between PVL and valve size in either cohort. CONCLUSIONS Utilization of 4G-BEV is associated with reduced PVL at 30 days post-TAVR compared with 3G-BEV.
