Association of Paravalvular Regurgitation With 1-Year Outcomes After Transcatheter Aortic Valve Replacement With the SAPIEN 3 Valve.

ABSTRACT: Importance:Moderate/severe and even mild paravalvular regurgitation (PVR) are associated with increased mortality following transcatheter aortic valve replacement (TAVR) with first and second generations of transcatheter valves. Objective:To examine the incidence, evolution, and effect on 1-year outcomes of PVR following TAVR with a third-generation balloon-expandable transcatheter heart valve. Design, Setting, and Participants:Prespecified analysis of PVR in the Placement of Aortic Transcatheter Valves (PARTNER) II SAPIEN 3 trial, conducted between October 1, 2013, and September 3, 2014. Multicenter, nonrandomized registry of 1661 patients at intermediate or high surgical risk undergoing TAVR with the SAPIEN 3. Patients with severe, symptomatic aortic stenosis and high/intermediate surgical risk were enrolled in the registry at 51 sites in the United States and Canada. Interventions:Transcatheter aortic valve replacement with the SAPIEN 3 valve. Main Outcomes and Measures:Paravalvular regurgitation was assessed in a core laboratory at 30 days and 1 year according to a 5-class scheme: 0, none or trace; 1, mild; 2, mild to moderate; 3, moderate; 4, moderate to severe; and 5, severe. We assessed the effect of PVR on 1-year mortality and heart failure rehospitalization. Results:Among the 1661 included in the registry, 1592 received a SAPIEN 3 valve and had assessment of PVR. Of these patients, 55.7% had none-trace PVR, 32.6% had mild, 8.2% had mild to moderate, and 3.5% had at least moderate PVR at 30 days. At 1 year, 9.3% of patients had died and 14.2% had been rehospitalized. Only patients with at least moderate PVR had higher 1-year mortality (hazard ratio [HR], 2.40; 95% CI, 1.30-4.43; P?=?.005) and composite of mortality/rehospitalization (HR, 2.35; 95% CI, 1.52-3.62; P?

Project description:ImportanceThe Centers for Medicare & Medicaid Services national coverage determination for transcatheter aortic valve replacement (TAVR) includes volume requirements for surgical aortic valve replacement (SAVR) for hospitals seeking to initiate or continue TAVR programs. Evidence regarding the association between SAVR volume and TAVR outcomes is limited.ObjectiveTo examine the association of hospital SAVR and combined SAVR and TAVR volumes with patient outcomes of TAVR procedures performed within 1 year, 2 years, and for the entire period after initiation of TAVR programs.Design, setting, and participantsThis observational cohort study included 60 538 TAVR procedures performed in 438 hospitals between October 1, 2011, and December 31, 2015, among Medicare beneficiaries.Main outcomes and measuresThe associations between SAVR volume, SAVR and TAVR volumes, and risks of death, death or stroke, and readmissions within 30 days were determined using a hierarchical logistic regression model adjusting for patient and hospital characteristics. The association between SAVR and SAVR and TAVR volumes and 1-year and 2-year mortality after TAVR procedures was determined using a multivariable proportional hazard model with a robust variance estimator. The associations for procedures performed within 1 year, 2 years, and for the entire period after initiation of TAVR programs were examined.ResultsAmong the 60 538 patients, 29 173 were women and 31 365 were men, with a mean (SD) age of 82.3 (8.0) years. Hospitals with high SAVR volume (mean annual volume, ≥97 per year) were more likely to adopt TAVR early and had a higher growth in TAVR volumes over time (median TAVR volume by hospitals with high SAVR volume and low SAVR volume: year 1, 32 vs 19; year 2, 48 vs 28; year 3, 82 vs 38; year 4, 118 vs 54; P < .001). In adjusted analysis, high hospital SAVR volume alone was not associated with better patient outcomes after TAVR. When hospital TAVR and SAVR volumes were jointly analyzed, patients treated in hospitals with high TAVR volume had lower 30-day mortality after TAVR (high TAVR and low SAVR vs low TAVR and low SAVR: odds ratio, 0.85; 95% CI, 0.72-0.99; high TAVR and high SAVR vs low TAVR and high SAVR: odds ratio, 0.81; 95% CI, 0.69-0.95), the effect of which was more pronounced when hospitals also had high SAVR volume. Patients treated in hospitals with high SAVR volume and high TAVR volume had the lowest 30-day mortality (vs hospitals with low SAVR volume and TAVR volume: odds ratio, 0.77; 95% CI, 0.66-0.89).Conclusions and relevanceHospitals with high SAVR volume are most likely to be fast adopters of TAVR. Hospital SAVR volume alone is not associated with better TAVR outcomes. Accumulating high volumes of TAVR is associated with lower mortality after TAVR, particularly when hospitals have high SAVR volumes. Hospitals with high caseloads of both SAVR and TAVR are likely to achieve the best outcomes.

Project description:BackgroundThe improvement rate and predictors of secondary mitral regurgitation in patients with aortic regurgitation undergoing transcatheter aortic valve replacement (TAVR) remain unclear. This study aimed to identify predictors of persistent moderate to severe secondary mitral regurgitation after TAVR in patients with aortic regurgitation by assessing mitral valve geometry with computed tomography (CT).MethodsThis retrospective cohort study reviewed 242 consecutive patients with aortic regurgitation who underwent TAVR between May 2014 and December 2022. Patients with primary or less than moderate mitral regurgitation were excluded. Mitral annular dimensions (area, perimeter, anteroposterior, intercommissural, and trigone-to-trigone diameter), mitral valve tenting geometry (mitral valve tenting area [MVTA] and mitral valve tenting height [MVTH]), and papillary muscle displacement were systematically measured at CT. Mitral regurgitation improvement was assessed at 3 months after TAVR by echocardiography. Logistic regression was performed to explore the association of mitral valve geometry with mitral regurgitation improvement after TAVR.ResultsA total of 75 patients (mean age, 74 ± 7 years; 32.0% female) with moderate to severe secondary mitral regurgitation were included in the final analysis. Mitral regurgitation improved in 49 patients and remained unchanged in 26 patients. Mitral annular dimensions, including area, perimeter, anteroposterior, and intercommissural diameter, were associated with mitral regurgitation improvement. MVTA and MVTH were risk factors for sustained mitral regurgitation. In addition, QRS duration > 120 ms and atrial fibrillation had an impact on the mitral regurgitation improvement. Mitral annular area (odds ratio [OR], 1.41; 95% confidence interval [CI]: 1.05, 1.90; p = 0.02) and MVTA (OR, 7.24; 95% CI: 1.72, 30.44; p = 0.007) were independent predictors of persistent secondary mitral regurgitation after TAVR.ConclusionsMitral annular area and MVTA were independent predictors of persistent secondary mitral regurgitation after TAVR.
