Abstract Aims Atrial fibrillation (AF) is associated with increased mortality after transcatheter aortic valve replacement (TAVR). Cerebrovascular complications and bleeding events associated with anticoagulation therapy are discussed to be possible causes for this increased mortality. The present study sought to assess whether AF is associated with impaired left ventricular (LV) reverse remodeling representing another possible mechanism for poor outcome. Methods All patients who underwent TAVR in our institution and had 1-year echocardiography follow-up were included. LV mass index (LVMI) at baseline and follow-up as well as LVMI change at 1 year were assessed with respect to the presence of AF (either at baseline or during hospitalization after TAVR) and sinus rhythm (SR). Results A total of 213 patients (n = 95 in AF; n = 118 in SR) were enrolled in the present study. Patients with AF had higher LVMI at 1 year compared to those with SR (173 ± 61 g/m2 vs. 154 ± 55 g/m2; p = 0.02) and they showed lower relative LVMI change at 1 year (− 2 ± 28% vs. − 9 ± 29%; p = 0.04). In linear regression analysis, AF was independently associated with relative LVMI change (regression coefficient ß 0.076 [95% CI 0.001–0.150]; p = 0.04). With respect to clinical outcome depending on AF and LVMI regression, the Kaplan–Meier estimated event-free of death or cardiac rehospitalization at 3 years was lowest among patients with AF and no LVMI regression. Conclusions The present study identified a significant association of AF with changes in LVMI after TAVR, which was also shown to be associated with clinical outcome.

Abstract Background Electrocardiographic (ECG) strain pattern has recently been associated with increased adverse outcome in aortic stenosis (AS) and after surgical aortic valve replacement (AVR). However, the relation linking ECG strain and cardiovascular MACE in patients with transcatheter aortic valve replacement (TAVR) has not been yet described. Objectives The aim of our study was to determine the impact and incremental value of ECG Strain pattern in predicting adverse outcome after TAVR. Methods 585 patients with severe AS (mean age: 83±7 male 39.8%) were enrolled from November 2012 to May 2018. ECG strain pattern was defined as ≥1 mm concave down-sloping ST-segment depression and asymmetrical T-wave inversion in the lateral leads. Patients with baseline left bundle branch block (LBBB), right bundle branch block (RBBB) or ventricular paced rhythm were excluded. All patients underwent transthoracic echocardiography (TTE) before TAVR and at 30 days follow up. The primary endpoints of the study were the overall all-cause mortality after TAVR, rehospitalization for Hearth failure (HF), myocardial infarction and stroke. Results 178 (30.4%) patients were excluded from analyses owing to the presence of either LBBB (n=103) or RBBB (n=75). Among the 407 remaining patients, 106 had ECG strain pattern (26.04%). Patients with ECG strain were significantly younger (81.6±8 years vs 83.5±6.8 years; p=0.022), had lower BMI (23±4.5 kg.m2 vs 27.9±6.8 kg.m2; p=0.02) more severe AS (mean gradient 52.3±15.2 mmHg vs 47.9±11.8 mmHg; p=0.003), significant lower LVEF (51.8±15% vs 58.4±10.7%; p<0.001). Left ventricular hypertrophy (LVH) was more frequent in patients with ECG Strain (indexed left ventricular mass (135.9±33.4 g.m2 vs 123.6±31.9 g.m2; p=0.002)). Death from any cause (22 (20.8%) vs 61 (20.3%); p=0.508) did not differ significantly between groups. Major adverse cardiovascular events (MACE) including death, stroke and heart failure at 1 month showed similar incidence (7 (6.6%) vs 17 (5.6%), p=0.439). Rehospitalization for hearth failure (HF) was significantly higher (33 (31.1%) vs 33 (11%); p<0.001) in patients with ECG strain pattern. In univariate model, ECG Strain was a strong predictor of rehospitalization for HF (HR 2.621 95% CI (1.607–4.277), p=0.001), independently of LVH assessed either by ECG criteria (HR 1.181 95% CI (0.698–1.997; p=0.536) or TTE (HR 1.557 95% (CI 0.701–3.458; p=0.277). ECG Strain remained associated with a higher risk of rehospitalization for hearth failure in multivariate analyses (HR 2.747 95% (CI 1.614- 4.674); p<0.001) Conclusion In patients with AS eligible for TAVR, ECG Strain Pattern is frequent and associated with an increased risk of post interventional heart failure regardless of preoperative LVH. ECG Strain pattern represents an easy, objective, reliable and low-cost tool to identify patients who may benefit from an extend and intensified post-interventional follow-up.

Abstract Background Aortic stenosis causes several changes in left ventricular (LV) geometry and function; cardiac remodeling after transcatheter aortic valve replacement (TAVR) is variable among patients and it is not clearly defined. The aim of this study is to identify factors associated with LV functional and structural recovery. Methods 428 patients were retrospectively studied; all patients underwent transthoracic echocardiography prior to TAVR; specific measurements such as maximum internal diameter of the prosthetic valve, nominal loss and percentage of nominal loss regarding to valve size, as well as the discongruence index (Prosthesis size/BSA) were evaluated at discharge and 1-year follow up. Positive cardiac remodeling (PCR) was considered if patients had a reduction of ≥20% of left ventricle mass index (LVMi) and ≥10% of end-diastolic volume index (LVEDVi). Results Mean age of the cohort was 83±5.6 years, 55% were female (n=236), mean aortic valve area was 0.7±0.2cm2; mean LVMi and LVEDVi were 129.4±35.4gr/m2 and 54.5±22ml/m2 respectively. LVMi reduction ≥20% was observed in 30% (n=128) of patients; LVEDVi reduction ≥10% was observed in 44% (n=188) of patients. A total of 107 patients (25%) showed PCR. Female patients showed more PCR (p=0.04). Discongruence index was significantly higher in patients with PCR (15.5±1.9 vs 14.5±1.8, p=0.01) and was significantly associated to LVMi (121.5±28.9 vs 150.8±41.1g/m2) and LVEDVi individually (55.1±17.2 vs 42.7±16.7ml/m2; p&lt;0.01). Left ventricular ejection fraction (LVEF) had a statistically significant increase among patients with PCR (53.2±14.9 vs 56.7±11.5, p=0.04) global longitudinal strain showed improvement at 1-year follow-up as well, although not statistically significant (−17.3±3.7 vs −18.3±3.4 p=0.53). Conclusions The discongruence index is a simple and feasible parameter that can predict positive cardiac remodeling after TAVR which can have a significant impact in clinical outcome of patients.

Abstract Background Incidence and correlates of readmission for heart failure in all-comers, after successful transcatheter aortic valve replacement (TAVR) remain unclear. Objective We sought to evaluate the incidence, risk factors and clinical impact of readmission for HF after successful TAVR in an unselected patient population. Methods All patients who underwent successful TAVR in two high-volume French tertiary centers from February 2010 to December 2016 were prospectively included and followed-up for one year. Cox multivariate model was used to assess risk factors of readmission for heart failure, evaluated a time-updated covariate and mortality. Results A total of 1139 patients (mean age 82.4±7.7 years, 52.2% male) were included. Readmission for heart failure occurred in 99 (8.7%) patients. Risk factors of readmission for HF were chronic pulmonary disease (adjHR 1.8; 95% CI [1.2–2.8], p=0.008), chronic kidney disease (adjHR 1.7; 95% CI [1.1–2.6], p=0.01), diabetes mellitus (adjHR 1.7; 95% CI [1.1–2.5], p=0.01), prior atrial fibrillation (adjHR 1.6; 95% CI [1.1–2.4], p=0.02) and post-TAVR left ventricular ejection fraction (LVEF) ≤35% (adjHR 2.1 95% CI 1.2–3.7, p=0.009). Readmission for HF was strongly associated with mortality (Figure) along with increased STS score (adjHR 1.07 95% CI 1.03–1.12, p=0.002), prior atrial fibrillation (adjHR 2.13 95% CI 1.53–2.96, p<0.001) and shock during the index hospitalization (adjHR 2.68 95% CI 1.48–4.87, p=0.001). Figure 1 Conclusion Readmission for heart failure occurs in one out of ten patients after successful TAVR and is strong risk factor of mortality. Comorbidities and post-TAVR LVEF≤35% are the main correlates of readmission for heart failure. Acknowledgement/Funding ACTION study group

Background - Conduction disturbances after transcatheter aortic valve replacement (TAVR) are often transient. Limited data exist on anatomic factors predisposing to PM dependency after TAVR. We sought to assess the rate and the possible predictors of pacemaker (PM) dependency after transcatheter aortic valve replacement (TAVR). Methods - Consecutive patients undergoing PM implantation up to 30-day after TAVR between May 2014 and September 2019 were included. Baseline electrocardiographic, computed tomography and procedural characteristics were collected, including valve implantation depth (ID) and membranous septum (MS) length, an anatomic surrogate of the distance between the aortic annulus and the His bundle. PM dependency at 30-day and 1-year and all-cause mortality during follow up were evaluated. Results - Of 728 TAVR patients, 112 (53.5% males, median age 81) underwent PM implantation after TAVR. Of these, 44.6% (50/112) were PM-dependent at 30-day, 46.7% (36/77) at 1-year. By multivariate analysis, independent predictors of 30-day PM dependency included left ventricular outflow tract (LVOT) calcifications under the left coronary cusp (LCC) (OR: 5.69, 95%CI: 1.45-22.31, p=0.013) and a difference between MS length and ID (ΔMSID) ≥3 mm (OR: 7.58, 95%CI: 2.07-27.78, p=0.002). Conversely, MS length and ID alone were not associated with PM dependency (OR: 0.79, 95%CI: 0.60-1.05, p=0.11 and OR: 1.11, 95%CI: 0.99-1.24, p=0.08). At a median follow-up of 28.1 [11.7-48.6] months, PM-dependent patients did not show a worse survival (p=0.26). Conclusions - Less than half of the patients undergoing PM implantation after TAVR are PM-dependent at mid-term follow-up. ΔMSID ≥3mm and presence of LVOT calcifications under the LCC, but not MS length nor ID alone, are predictive of long-term PM dependency after TAVR, thus influencing device selection and programming.

Introduction: Pre-existing atrial fibrillation has been linked with poor outcomes among patients undergoing transcatheter aortic valve replacement (TAVR). Objective: We sought to study the impact of baseline atrial fibrillation/flutter (AF) on outcomes after TAVR with SAPIEN-3 (S3) valve. Methods: All consecutive patients with severe symptomatic aortic stenosis who underwent TAVR with S3 valve at the Cleveland Clinic between April 2015 and December 2018 were included. Results: We included 1028 consecutive patients. Overall, the mean age of our study population was 81 ± 8.9 years, 58.8% were males, 95.8% were Caucasians. Pre-existing AF was present in 432 patients (42%). STS risk score was higher with AF compared to no AF (6.7 ± 3.8% vs. 5.4 ± 3.4%; p < 0.001). Baseline left ventricular ejection fraction (LVEF) was lower with AF (54% vs. 58%; p < 0.001). The rates of 30-day permanent pacemaker (PPM) implantation were similar between AF and no AF (11.4% vs. 9.4%; p = 0.326), as were the rates of new-onset left bundle branch block (LBBB) at discharge (9.6% vs. 9.4%; p = 0.901). There was also no difference in stroke rates at 30 days between the 2 groups (1.6% vs. 1%; p = 0.385). Post-TAVR mild or greater aortic regurgitation (AR) was higher with AF compared to no AF (21.5% vs. 16%; p = 0.022). LVEF was lower with AF at both 30 days (56% vs. 58.5%; p < 0.001) and 1 year (56% vs. 59%; p < 0.001). However, the change in LVEF (Δ) after TAVR was similar between AF and no AF (+1.1% vs. +1.4%; p = 0.624). At 2 years, all-cause death was higher with AF (22.9% vs. 12.8%; log-rank p = 0.011). There was no mortality difference between persistent versus paroxysmal AF (log-rank p = 0.714). Conclusions: Among our S3 TAVR patients, AF did not affect PPM, new-onset LBBB or stroke rates after the procedure. AF was associated with higher mild or greater AR at 30 days, as well as lower LVEF at both 30 days and 1 year compared to no AF. There was significantly higher all-cause mortality in the AF group at 2 years after TAVR.

AbstractOur study aimed to compare the difference of LV mass regression and remodeling in regard of conduction disturbances (CD) following transcatheter aortic valve replacement (TAVR). A prospective analysis of 152 consecutive TAVR patients was performed. 53 patients (34.9%) had CD following TAVR, including 30 (19.7%) permanent pacemaker implantation and 23 (15.2%) new left bundle branch block. In 123 patients with 1-year follow-up, significant improvement of LV ejection fraction (LVEF) (baseline vs 12-month: 65.1 ± 13.2 vs 68.7 ± 9.1, P = 0.017) and reduced LV end-systolic volume (LVESV) (39.8 ± 25.8 vs 34.3 ± 17.1, P = 0.011) was found in non-CD group (N = 85), but not in CD group (N = 38). Both groups had significant decrease in LV mass index (baseline vs 12-month: 148.6 ± 36.9 vs. 136.4 ± 34.7 in CD group, p = 0.023; 153.0 ± 50.5 vs. 125.6 ± 35.1 in non-CD group, p < 0.0001). In 46 patients with 3-year follow-up, only non-CD patients (N = 28) had statistically significant decrease in LV mass index (Baseline vs 36-month: 180.8 ± 58.8 vs 129.8 ± 39.1, p = 0.0001). Our study showed the improvement of LV systolic function, reduced LVESV and LV mass regression at 1 year could be observed in patients without CD after TAVR. Sustained LV mass regression within 3-year was found only in patients without CD.

Abstract Background Patients with severe aortic regurgitation (AR) are treated by surgery and have variable left-ventricular (LV) “reverse remodelling” after intervention. Transcatheter-aortic-valve replacement (TAVR) might be considered in selected AR patients. Purpose To evaluate the hemodynamic and structural impact of TAVR in patients with pure AR. Methods Consecutive AR patients underwent TAVR in our Institution were identified. Left heart catheterization before and after TAVR and complete echocardiographic assessment before TAVR, after (24–72 hours) TAVR and at follow-up (3–12 months) were systematically performed. Hemodynamic and echocardiographic parameters were compared before and after TAVR. Results Twenty-two patients with severe AR, high surgical risk and advanced heart damage were treated by TAVR using mainly self-expandable prostheses. The procedure was successful in 21 patients (95.5%). An immediate hemodynamic impact of the TAVR procedure was documented by different parameters and included significant decrease in LV end-diastolic pressure (from 26.2 to 20.1 mmHg, P=0.012). Significant reduction in LV size (left ventricular end diastolic diameter (LVEDD): 60.0±8.0 mm vs 54.6±8.1 mm, p=0.002) and mass (left ventricular mass indexed (LVMi): 163.2±58.8 g/m2 vs 140.2±45.6 g/m2, p 0.004) as well as a sharp reduction in systolic-pulmonary-arterial-pressure (48.3±17.6 vs 32.9±7.8 mmHg, p&lt;0.0001) was documented at 24–72 hours. Furthermore, patients with baseline moderate-to-severe mitral and tricuspid regurgitation showed a significant, early, valvular regurgitation reduction. All favourable changes persisted at follow-up. More pronounced LVEDD reduction was predicted by baseline LVEDD (p=0.019). Conclusions In patients with severe AR, TAVR determines a profound impact on heart remodelling, which is early detectable and durable.

Background: Transcatheter aortic valve replacement (TAVR) in patients with pure aortic regurgitation (AR) is still “off-label” use due to the lack of suitable transcatheter heart valve. This study aimed to evaluate the safety and efficacy of TAVR with J-Valve TM (JieCheng Medical Technology Co., Ltd., Suzhou, China) transcatheter heart valve for the treatment of patients with pure non-calcified native AR. Methods: The clinical and follow-up data of patients with pure non-calcified native AR treated by TAVR with J-Valve TM between April 2014 and November 2019 in the West China Hospital were summarized. Procedural results and clinical outcomes were analyzed using Valve Academic Research Consortium-2 criteria. Results: A total of 123 patients were enrolled with a mean age of 72.1±6.4 years. There were 28 cases with bicuspid aortic valve and 95 cases with trilobal aortic valve. The median follow-up period was 18 months. Transapical implantation with J-Valve TM was successful in all patients (100%). By the end of the follow up, the rate of all-cause mortality was 5.7%, among which 5 cases died during the perioperative period. Other results include stroke (1.6%), new permanent pacemaker implantation (8.9%), major bleeding (6.5%), acute kidney injury (2.4%) and aortic valve-related re-intervention (3.3%, they were given surgical aortic valve replacement for thrombosis of artificial valve (2 cases) or severe post-procedural paravalvular leakage (2 cases)). Among the 112 survival cases without re-intervention, Echocardiography revealed that none of them had moderate or severe paravalvular leakage; mild and mild-moderate paravalvular leakage occurred in 9.8% and 8.0% cases, respectively. Mean transvalvular gradient after valve implantation was 9.2±3.5 mmHg. At 6 months of follow up, left ventricular end diastolic diameter was remarkably smaller compared to that before procedure (53.5±8.2 mm vs 64.3±8.9 mm, P<0.001) and left ventricular ejection fraction was significantly increased (56.3±11.8 % vs 54.2±12.4 %, P=0.031). Conclusions: TAVR with J-Valve TM transcatheter heart valve system for treatment of patients with pure non-calcified native AR is safe and effective which may be a reasonable option in the future treatment.
