Transcatheter aortic valve implantation in patients with a small aortic annulus: performance of supra-, intra- and infra-annular transcatheter heart valves.

ABSTRACT:

Background

A small aortic annulus is associated with increased risk of prosthesis-patient mismatch (PPM) after transcatheter aortic valve implantation (TAVI). Whether specific transcatheter heart valve (THV) designs yield superior hemodynamic performance in these small anatomies remains unclear.

Methods

Data from 8411 consecutive patients treated with TAVI from May 2012 to April 2019 at four German centers were retrospectively evaluated. A small aortic annulus was defined as multidetector computed tomography-derived annulus area < 400 mm². TAVI was performed with a balloon-expanding intra-annular (Sapien-3, n = 288), self-expanding intra-annular (Portico, n = 110), self-expanding supra-annular (Evolut, n = 179 and Acurate-Neo, n = 428) and mechanically expanding i
