Supra-Annular Self-Expanding Versus Balloon-Expandable Valves for Valve-in-Valve Transcatheter Aortic Valve Replacement.

ABSTRACT: Self-expanding (SE) and balloon-expandable (BE) transcatheter heart valves (THVs) have not been extensively studied in valve-in-valve (ViV) transcatheter aortic valve replacement (TAVR). We compared outcomes of supra-annular SE and BE THVs used for ViV-TAVR through a retrospective analysis of institutional data (2013 to 2023) including all patients who underwent ViV-TAVR (TAVR in previous surgical aortic valve replacement). Unmatched and propensity-matched (1:1) comparisons of clinical and echocardiographic outcomes were undertaken in SE and BE THVs along with Kaplan-Meier survival analysis. A total of 315 patients who underwent ViV-TAVR were included, of whom 73% received an SE THV. Median age was 77 years, and women comprised 42.5% of the population. Propensity-score matching (1:1) yield
