Paravalvular leaks (PVLs) are not uncommon after surgical valve replacement. The need for re-operation for clinically significant leaks is between 1 and 3%.1 Percutaneous PVL closure has become increasingly performed and is an alternative to surgery.1 PVLs occur more frequently after transcatheter aortic valve implantation (TAVI), as the transcatheter heart valve (THV) is anchored by radial force alone.2 The experience of percutaneous repair of significant paravalvular aortic regurgitation (AR) after TAVI is limited. We report a case of heart failure due to severe PVL after TAVI that has been treated with percutaneous repair with a good 4-year clinical outcome.
