Transcatheter bicuspid versus tricuspid aortic valve replacement in patients with a small aortic annulus: an observational study.

ABSTRACT:

Objective

To compare the clinical outcomes and haemodynamic performance following transcatheter aortic valve replacement (TAVR) in patients with severe bicuspid versus tricuspid aortic stenosis (AS) and small annuli.

Design

Retrospective analysis based on a prospective observational cohort.

Setting

Single-centre registry of patients undergoing TAVR between 2016 and 2023.

Participants

A total of 427 patients (193 bicuspid (BAV) and 234 tricuspid (TAV) aortic valve) with symptomatic severe AS and small annuli (median area 381.5 mm² (IQR 348.0-406.4)), all undergoing preprocedural multidetector CT and standardised follow-up echocardiography.

Main outcomes measure

Baseline characteristics, technical success, procedural complications, haemodynamic
