The aim of this study, – based on data prospectively collected in the Italian Transcatheter balloon-Expandable Registry (ITER) on aortic stenosis (AS) patients, – was to investigate interactions among pre-procedural aortic regurgitation (AR), post-procedural paravalvular leak (PVL) and long-term clinical outcomes.

The Authors conclude that, in patients with severe AS treated with balloon-expandable TAVI, the presence of paravalvular leak (PVL), but not pre-procedural aortic regurgitation, was a major predictor of adverse outcome. Preoperative LV dilatation seemed to offer some clinical advantages.
