Abstract

ABSTRACT Background: Bicuspid aortic valve (BAV) is a significant risk factor for aortic stenosis (AS). Yet, the outcomes of transcatheter aortic valve implantation (TAVI) remain unclear, as most randomized trials excluded such patients. Furthermore, most published evidence on TAVI in BAV comes from high-income countries, which may not reflect realities of underserved populations. Objectives: Evaluate temporal trends, procedural, and in-hospital outcomes between BAV and tricuspid aortic valve (TAV) patients. Methods: Retrospective observational study based on a Brazilian multicenter registry of TAVI patients between January 2009 and December 2021. We performed propensity score matching to adjust comparisons. A p-value
