Key result
Balloon post-dilation successfully treats transcatheter valve infolding, reducing mean gradient by ~19 mmHg.
Why the study?
Frame infolding is an increasingly recognized complication during deployment of self-expandable transcatheter aortic valves, with limited guidance on management.

Transcatheter aortic valve replacement (TAVR) with either a balloon-expandable or a self-expandable transcatheter heart valve (THV) is an approved therapy for patients with symptomatic severe aortic stenosis and high or intermediate surgical risk. Here we present a case of severe valve frame infolding of a CoreValve Evolut PRO® self-expandable THV (Medtronic Inc.), which was restored to optimal geometry with balloon post-dilation.

Singh et al. (2020) conducted a case report in symptomatic severe aortic stenosis (n=1). Balloon post-dilation of infolded transcatheter heart valve was evaluated.
