ObjectivesTo determine the prevalence and factors associated with persistent pulmonary hypertension (PH) following transcatheter aortic valve replacement (TAVR) and its relationship with long-term mortality.MethodsConsecutive patients who underwent TAVR from July 2011 through January 2016 were studied. The prevalence of baseline PH (mean pulmonary artery pressure ≥25 mm Hg on right heart catheterisation) and the prevalence and the predictors of persistent≥moderate PH (pulmonary artery systolic pressure (PASP)>45 mm Hg on 1 month post-TAVR transthoracic Doppler echocardiography) were collected. Cox models quantified the effect of persistent PH on subsequent mortality while adjusting for confounders.ResultsOf the 407 TAVR patients, 273 (67%) had PH at baseline. Of these, 102 (25%) had persistent≥moderate PH. Mortality at 2 years in patients with no baseline PH versus those with PH improvement (follow-up PASP≤45 mm Hg) versus those with persistent≥moderate PH was 15.4%, 16.6% and 31.3%, respectively (p=0.049). After adjusting for Society of Thoracic Surgeons Predicted Risk of Mortality and baseline right ventricular function (using tricuspid annular plane systolic excursion), persistent≥moderate PH remained associated with all-cause mortality (HR=1.82, 95% CI 1.06 to 3.12, p=0.03). Baseline characteristics associated with increased likelihood of persistent≥moderate PH were ≥moderate tricuspid regurgitation, ≥moderate mitral regurgitation, atrial fibrillation/flutter, early (E) to late (A) ventricular filling velocities (E/A ratio) and left atrial volume index.ConclusionsPersistency of even moderate or greater PH at 1 month post-TAVR is common and associated with higher all-cause mortality.

The Relationship

Introduction: Pulmonary hypertension (PH) is associated with increased mortality after surgical or transcatheter aortic valve replacement (TAVR) for aortic stenosis (AS). Hypothesis: We hypothesized that clinical or hemodynamic factors might influence the relationship between significant PH and increased mortality. Methods: Among patients with symptomatic AS at high or prohibitive surgical risk receiving TAVR in the PARTNER I randomized trial or registry, 2180 patients with an invasive measurement of mean pulmonary artery pressure (mPAP) recorded were included. PH was defined as: none (mPAP<25 mmHg), mild (25 to <35), and mod/sev (≥35). Results: One year all-cause mortality was worse with increasing severity of PH: none (n=785, 18.6%), mild (n=838, 22.7%), and mod/sev (n=557, 25.0%) (p=0.01). The association between mod/sev PH (vs. no PH) and 1y mortality varied by sex and renal function (interaction p=0.03 and p=0.06, respectively). In females, mod/sev PH was associated with increased mortality (24.6% vs. 14.1%, HR 1.89, 95% CI 1.32-2.73); in males it was not (24.9% vs. 22.2%, HR 1.12, 95% CI 0.82-1.52). Additionally, mod/sev PH was associated with mortality in those with glomerular filtration rate (GFR) <40 (HR 1.76, 95% CI 1.28-2.42), but not in those with GFR ≥40. In a multivariable Cox PH model of patients with mod/sev PH, oxygen dependent lung disease, cerebrovascular disease, lower GFR, and lower baseline transvalvular mean gradient were each independently associated with increased 1y mortality (p<0.05 for all), whereas pulmonary artery compliance was the only hemodynamic variable associated with mortality (p=0.043) (Table). Conclusions: The relationship between mod/sev PH and increased mortality after TAVR is altered by sex and renal function. While lower pulmonary artery compliance is associated with increased mortality in patients with significant PH, clinical factors appear to be more influential in stratifying risk than hemodynamic indices.

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.

Background: Heart failure (HF) readmission is common post–transcatheter aortic valve replacement (TAVR). Nonetheless, limited data are available regarding its predictors and clinical impact. This study evaluated the incidence, predictors, and impact of HF readmission within 1-year post-TAVR, and assessed the effects of the prescription of HF therapies at discharge on the risk of HF readmission and death. Methods: Patients included in the TAVR registry of a single expert center from 2009 to 2017 were analyzed. Competing-risk and Cox regressions were performed to identify predictors of HF readmission and death. Results: Among 750 patients, 102 (13.6%) were readmitted for HF within 1-year post-TAVR. Overall, 53 patients (7.1%) experienced late readmissions (>30 days post-TAVR), and 17 (2.3%) had multiple readmissions. In ≈30% of readmissions, no trigger could be identified. Predominant causes of readmissions were changes in medication/nonadherence and supraventricular arrhythmia. Independent predictors of HF readmission included diabetes mellitus, chronic lung disease, previous acute HF, grade III or IV aortic regurgitation, and pulmonary hypertension both at discharge from the index hospitalization but not HF therapies. Overall, HF readmission did not significantly impact all-cause mortality (hazard ratio [HR], 1.36 [95% CI, 0.99–1.85]). However, late (HR, 1.90 [95% CI, 1.30–2.78]) and multiple HF readmissions (HR, 2.10 [95% CI,1.17–3.76]) were significantly associated with all-cause mortality. Prescription of renin-angiotensin system inhibitors at discharge was associated with a lower rate of all-cause mortality, especially among patients receiving doses of 25% to <50% (HR, 0.67 [95% CI, 0.48–0.94]) and 75% to 100% (HR, 0.61 [95% CI, 0.37–0.98]) of the optimal daily dose. Conclusions: HF readmission is common within 1-year of TAVR. Late and multiple HF readmissions associate with an increased risk of long-term all-cause mortality. Baseline comorbidities (diabetes, chronic lung disease, previous acute HF) and echocardiographic findings at discharge (grade III or IV aortic regurgitation, pulmonary hypertension) identified patients at high risk of HF readmission.

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 &lt; 0.001}, shorter ICU LOS [0.0 (IQR 0.0–0.0) vs 1.0 (IQR 1.0–3.0) days, P &lt; 0.001] and shorter hospital LOS [7.0 (IQR 5.0–9.5) vs 14.0 (IQR 10.0–22.0) days, P &lt; 0.001]. CONCLUSIONS The TC approach may be a good first-choice alternative in case of contraindications to transfemoral-TAVR.
