  • Center valve preference and outcomes of transcatheter aortic valve replacement : insights from the AMTRAC registry
    Witberg, Guy ...
    Background: Data on outcomes of transcatheter aortic valve replacement (TAVR) using balloon-expandable valves (BEVs) or self-expandable valves (SEVs) as well as the impact of center valve preference ... on these outcomes are limited. Objectives: The aim of this study was to compare outcomes of TAVR procedures using third-generation BEVs and SEVs stratified by center valve preference. Methods: In a multicenter registry (n = 17), 13 centers exhibited valve preference (66.6%-90% of volume) and were included. Outcomes were compared between BEVs and SEVs stratified by center valve preference. Results: In total, 7,528 TAVR procedures (3,854 with SEVs and 3,674 with BEVs) were included. The mean age was 81 years, and the mean Society of Thoracic Surgeons score was 5.2. Baseline characteristics were similar between BEVs and SEVs. Need for pacemaker implantation was higher with SEVs at BEV- and SEV-dominant centers (17.8% vs 9.3% [P < 0.001] and 12.7% vs 10.0% [P = 0.036], respectively; HR: 1.51; P for interaction = 0.021), risk for cerebrovascular accident was higher with SEVs at BEV-dominant but not SEV-dominant centers (3.6% vs 1.1% [P < 0.001] and 2.2% vs 1.4% [P = 0.162]; HR: 2.08; P for interaction < 0.01). Aortic regurgitation greater than mild was more frequent with SEVs at BEV-dominant centers and similar with BEVs regardless of center dominance (5.2% vs 2.8% [P < 0.001] and 3.4% vs 3.7% [P = 0.504], respectively). Two-year mortality was higher with SEVs at BEV-dominant centers but not at SEV-dominant centers (21.9% vs 16.9% [P = 0.021] and 16.8% vs 16.5% [P = 0.642], respectively; HR: 1.20; P for interaction = 0.032). Conclusions: Periprocedural outcomes, aortic regurgitation greater than mild, and 2-year mortality are worse when TAVR is performed using SEVs at BEV-dominant centers. Outcomes are similar regardless of valve type at SEV-dominant centers. The present results stress the need to account for this factor when comparing BEV and SEV outcomes.
