Restoration of a Stuck Leaflet

Catheterization and Cardiovascular Interventions, Volume 106, Issue 1, Page 527-529, July 1, 2025.
ABSTRACT Severe aortic regurgitation (AR) for a leaflet malfunction after transcatheter aortic valve implantation (TAVI) is a dreadful complication that can lead even to cardiogenic shock. New valve's design has reduced the rate of paravalvular regurgitation, however central regurgitation is still a challenging complication.
