Abstract

Transcatheter mitral valve implantation is an emerging technology for the treatment of inoperable or high-risk patients with symptomatic severe mitral regurgitation. Known technical issues are obstruction of the left ventricular outflow tract, paravalvular leakage, and hemolysis. We report a case of valve retensioning successfully resolving paravalvular leakage and hemolysis. (Level of Difficulty: Intermediate.).

Keywords: LVOT, left ventricular outflow tract; LVOTO, left ventricular outflow tract obstruction; MV, mitral valve; PVL, paravalvular leak; TMVI, transcatheter mitral valve implantation; hemodynamic status; mitral valve; valve replacement.
