Key result
TAV-in-TAV observational cohort details clinical characteristics and outcomes for bioprosthetic valve dysfunction.
Why the study?
With more TAVI performed in younger patients, concerns arose regarding valve durability and treatment once index prostheses degenerate.
What are the clinical characteristics and outcomes of patients with TAVI bioprosthetic valve dysfunction treated with TAV-in-TAV?

What are the clinical characteristics and outcomes of patients with TAVI bioprosthetic valve dysfunction treated with TAV-in-TAV?
This study aims to describe the clinical characteristics and outcomes of patients undergoing TAV-in-TAV for TAVI bioprosthetic valve dysfunction.
Descriptive TAV-in-TAV cohort data; leaves open comparative safety and efficacy versus alternatives.
Transcatheter aortic valve implantation (TAVI) is an efficacious treatment for aortic stenosis (AS).1,2 With more TAVI performed in younger patients, concerns about durability/treatment once index prostheses degenerate arose.3 We examined data to evaluate clinical characteristics of patients with TAVI bioprosthetic valve dysfunction (BVD) and treatment with transcatheter aortic valve (TAV)-in-TAV at a tertiary cardiac centre.

Ewe et al. (2025) conducted an observational in TAVI bioprosthetic valve dysfunction. TAV-in-TAV was evaluated. The abstract outlines a study evaluating the clinical characteristics and outcomes of TAV-in-TAV for bioprosthetic valve dysfunction, but provides no quantitative results.
