Abstract OBJECTIVES Transfemoral approach is the standard access-route for transcatheter aortic valve replacement (TAVR). However, alternative approaches are needed in a number of patients and accesses such as transapical (TA) TAVR or transcervical (TC) are used. We aimed to compare clinical and echocardiographic outcomes after TA-TAVR or TC-TAVR. METHODS All patients who underwent TA- and TC-TAVR for severe aortic stenosis in our institution between 2008 and 2020 were retrospectively included. End points included 30-day all-cause mortality, procedural complications (according to the Valve Academic Research Consortium-2 criteria), procedure duration, intensive care unit (ICU) length of stay (LOS) and overall hospital LOS. For 30-day all-cause mortality, we furthermore used a Cox proportional-hazards model to adjust for significant between-group differences in baseline characteristics as well as difference in year of intervention. RESULTS TAVR was performed in 176 patients, using a TA approach (n = 127) or a TC approach (n = 49). Baseline clinical and echocardiographic characteristics were comparable between the 2 groups, except age and peripheral artery disease. All-cause 30-day mortality rates were not significantly different (8.5% in the TA group vs 2.3% in the TC group, P = 0.124). TC approach was associated with significantly shorter procedure duration {71.0 [interquartile range (IQR) 52.5–101.0] vs 93 [IQR 80.0–120.0] min, P < 0.001}, shorter ICU LOS [0.0 (IQR 0.0–0.0) vs 1.0 (IQR 1.0–3.0) days, P < 0.001] and shorter hospital LOS [7.0 (IQR 5.0–9.5) vs 14.0 (IQR 10.0–22.0) days, P < 0.001]. CONCLUSIONS The TC approach may be a good first-choice alternative in case of contraindications to transfemoral-TAVR.

Background Although current guidelines recommend dual antiplatelet therapy (DAPT) for 3 to 6 months following transcatheter aortic valve replacement (TAVR), there are no studies directly comparing outcomes of different durations of DAPT following TAVR. Methods and Results PubMed, EMBASE, and Cochrane Database were searched through November 2020 to identify clinical studies that investigated single antiplatelet therapy versus DAPT use following TAVR. Studies using oral anticoagulants and antiplatelet therapy concomitantly were excluded. The DAPT group was subdivided by the duration of DAPT. We extracted the risk ratios (RRs) of major or life‐threatening bleeding, stroke, and all‐cause mortality. Four randomized controlled trials, 2 propensity‐score matched studies, and 1 observational study were identified, yielding a total of 2498 patients who underwent TAVR assigned to the single antiplatelet therapy group (n=1249), 3‐month DAPT group (n=485), or 6‐month DAPT group (n=764). Pooled analyses demonstrated that when compared with the single antiplatelet therapy group, the rates of major or life‐threatening bleeding were significantly higher in the 3‐ and 6‐month DAPT groups (RR [95% CI]=2.13 [1.33–3.40], P =0.016; RR [95% CI]=2.54 [1.49–4.33], P =0.007, respectively) with no difference between the 3‐month DAPT versus 6‐month DAPT groups. The rates of stroke and all‐cause mortality were similar among the 3 groups. Conclusions In this network meta‐analysis of antiplatelet therapy following TAVR, single antiplatelet therapy with aspirin had lower bleeding without increasing stroke or death when compared with either 3‐ or 6‐month DAPT.

Abstract Aims This study aimed to assess the impact of valvular/subvalvular calcium burden on procedural and long-term outcomes in patients undergoing transcatheter aortic valve replacement (TAVR) for severe aortic stenosis (AS). Methods and results In this prospective observational cohort study, we included patients with AS undergoing TAVR between March 2010 and December 2019. Calcium burden at baseline was quantified using multidetector computed tomography and the patients were classified into tertile groups according to the amount of calcium. Procedural outcomes [paravalvular leakage (PVL) or permanent pacemaker insertion (PPI)] and 12-month clinical outcomes (composite of death, stroke, or rehospitalization, and all-cause mortality) were assessed. A total of 676 patients (age, 79.8 ± 5.4 years) were analysed. The 30-day rates of moderate or severe PVL (P-for-trend = 0.03) and PPI (P-for-trend = 0.002) proportionally increased with the tertile levels of calcium volume. The 12-month rate of primary composite outcomes was 34.2% in low-tertile, 23.9% in middle-tertile, and 25.8% in high-tertile groups (log-rank P = 0.02). After multivariable adjustment, the risk for primary composite outcomes at 12 months was not significantly different between the tertile groups of calcium volume [reference = low-tertile; middle-tertile, hazard ratio (HR) 0.81; 95% confidence interval (CI) 0.54–1.22; P = 0.31; high-tertile, HR 0.93; 95% CI 0.56–1.57; P = 0.80]. A similar pattern was observed for all-cause mortality. Conclusion The rates of PVL and PPI proportionally increased according to the levels of valvular/subvalvular calcium volume, while the adjusted risks for composite outcomes and mortality at 12 months were not significantly different.

Galectin 3

Abstract Background: Galectin-3 may predict mortality for patients with aortic stenosis (AS) after transcatheter aortic valve replacement (TAVR). However, the results were inconsistent. We aimed to evaluate the association between baseline galectin and mortality after TAVR in a meta-analysis. Methods: Related follow-up studies were obtained by systematic search of PubMed, Cochrane’s Library, and Embase databases. Both the fixed- and the random-effect models were used for the meta-analysis. Subgroup analyses were performed to evaluate the influences of study characteristics on the outcome. Results: Five prospective cohort studies with 854 patients were included, with a follow-up period between 1 and 1.9 years. Patients with higher baseline circulating galectin-3 had an increased risk of all-cause mortality after TAVR (random-effects model: risk ratio [RR]: 1.63, 95% confidence interval [CI]: 1.19–2.23, P=0.002; fixed-effects model: RR: 1.62, 95% CI: 1.19–2.20, P=0.002; I2 = 4%). Adjustment of estimated glomerular filtration rate (RR: 1.73, P=0.02) or B-type natriuretic peptide (BNP) or N-terminal pro-BNP (RR: 1.83, P=0.02) did not significantly affect the result. A trend of stronger association between higher baseline circulating galectin-3 and increased risk of all-cause mortality after TAVR was observed in studies with an enzyme-linked fluorescent assay (ELFA) (RR: 3.04, P=0.003) compared with those with an enzyme-linked immunosorbent assay (ELISA) (RR: 1.42, P=0.04; P for subgroup difference =0.06). Conclusion: Higher circulating galectin-3 before the procedure may predict all-cause mortality of AS patients after TAVR.

Abstract Objective The aim of this study is to assess the effects on procedural, 30-day, and 1‑year all-cause mortality by a newly introduced quality improvement strategy in patients after transcatheter aortic valve replacement (TAVR). Methods In October 2015, a coherent set of quality improving interventions with respect to patient geriatric screening, general diagnostic examination and safety of the procedure was implemented at a single centre in the Netherlands. Patients undergoing TAVR in 2013–2018 were included for retrospective analysis. Mortality was assessed in the pre-quality improvement strategy cohort (January 2013 to October 2015; cohort A) and in the post-quality improvement strategy cohort (November 2015 to December 2018; cohort B). Logistic regression analysis was used to estimate the influence of patient and procedural characteristics on the results of the quality improvement strategy in terms of procedural, 30-day, and 1‑year all-cause mortality. Results In total, 806 patients were analysed with 274 patients in cohort A and 532 patients in cohort B. After introduction of the quality improvement strategy, procedural (4.4% to 1.3%, p < 0.01), 30-day (8.4% to 2.7%, p < 0.01) and 1‑year (16.4% to 8.5%, p < 0.01) all-cause mortality significantly decreased. Multivariate regression analysis showed that the quality improvement strategy also significantly reduced 30-day (odds ratio [OR] 0.19, 95% confidence interval [CI] 0.09–0.42) and 1‑year (OR 0.38, 95% CI 0.24–0.61) all-cause mortality if corrected for patient characteristics. Conclusion Structural meetings on evaluation of outcomes highlight potential areas for improvement and subsequent outcome-based quality improvement initiatives can result in lower procedural, 30-day, and 1‑year all-cause mortality.

Objective: To compare 30 days mortality and clinical outcomes between transapical transcatheter aortic valve replacement (TA-TAVR) and transfemoral transcatheter aortic valve replacement (TF-TAVR) in Thai patients who underwent transcatheter aortic valve replacement (TAVR). Materials and Methods: The observational study included 83 consecutive patients that attended the authors’ center for TAVR between January 2009 and December 2019. The patients’ baseline demographic data and surgical risks were recorded. The clinical outcomes at 30 days and one year were prespecified targets. Results: Eighty-three patients underwent TAVR at the authors’ center between 2009 and 2019, with 77% of them considered inoperable or at high surgical risk by the authors’ heart team. Of the 83 patients, 40 had a porcelain aorta (48.2%). The median Society of Thoracic Surgeons (STS) score and logistic EuroSCORE were 5.7 (4.6, 8.3) and 21.7 (15.2, 31.2), respectively. Twenty-two patients had a transapical approach (26.5%). The cardiovascular (CV) mortality rate was 2.4% at 30 days. The all-cause mortality 30-day rate and 1-year rate were 3.6% and 12.0%, respectively. Comparing between TA-TAVR and TF-TAVR, TA-TAVR had a significantly lower incidence of new permanent pacemaker placement after TAVR (p=0.032), but a longer length of hospital stay (p=0.087). There was a trend for a higher incidence of new onset atrial fibrillation in TA-TAVR. The all-cause mortality 30-day rate and 1-year rate were similar between TA-TAVR and TF-TAVR. Conclusion: In Thai symptomatic severe aortic stenosis patients, of whom most patients were considered inoperable or at high surgical risk, both TA-TAVR and TF-TAVR showed acceptable short- and long-term clinical outcomes.

<b><i>Background:</i></b> Risk stratification in patients post-transcatheter aortic valve replacement (TAVR) is limited to and is based on clinical judgment and surgical scoring systems. Serum natriuretic peptides are used for general risk stratification in patients with aortic stenosis, reflecting the increase in their afterload and thereby stressing the need for valve intervention. The objective of this study was to determine the predictive value of pre- and post-procedural serum brain natriuretic peptide (BNP) on 1-year all-cause mortality in patients who underwent TAVR. <b><i>Methods:</i></b> In this population-based study, we included 148 TAVR patients treated at the Poriya Medical Center between June 1, 2015, and May 31, 2018. Routine blood samples for serum BNP levels (pg/mL) were taken just before the TAVR and 24 h post-TAVR. Our primary clinical outcome was defined as 1-year all-cause mortality. We used backward regression models and included all variables that had a <i>p</i> value &#x3c;0.1 in the univariable analysis. A receiver-operating characteristic curve was calculated for the prediction of all-cause mortality by serum BNP levels using the median as the cut-off point. <b><i>Results:</i></b> In this study cohort, BNP levels 24 h post-TAVR higher than the cohort median versus lower than the cohort median (387.5 pg/mL; IQR 195–817.6) were the strongest predictor of 1-year mortality (hazard ratio 9; 95% CI 2.72–30.16; <i>p</i> &#x3c; 0.001). The statistically significant relationship was seen in the unadjusted regression model as well as after the adjustment for clinical variables. <b><i>Conclusions:</i></b> Serum BNP levels 24 h post-procedure were found to be a meaningful marker in predicting 1-year all-cause mortality in patients after TAVR procedure.
