Five-year outcomes of mild paravalvular regurgitation after transcatheter aortic valve implantation.

ABSTRACT:

Background

Mild paravalvular regurgitation (PVR) remains a frequent and underappreciated adverse event after transcatheter aortic valve implantation (TAVI) despite remarkable progress in device technology and implantation technique.

Aims

This study sought to investigate the impact of mild PVR after TAVI on five-year clinical outcomes.

Methods

In a prospective TAVI registry, PVR prior to discharge was retrospectively assessed in an echocardiographic core laboratory. Patients with ≥moderate PVR were excluded. Mild PVR was categorised into mild and mild-to-moderate PVR using a recently proposed unifying 5-class grading scheme.

Results

A total of 1,128 patients undergoing TAVI between 2007 and 2015 were enrolled. Of these, 560 patients had mild PVR, including 433 w
