P1798 Determinants of increased mitral mean diastolic gradient after transcatheter edge-to-edge mitral valve repair

Background Transcatheter edge-to-edge mitral valve repair (TMVR; MitraClip, Abbott Vascular) is clinically approved for treatment of severe, symptomatic mitral regurgitation (MR) in high or prohibitive surgical risk patients. Iatrogenic mitral stenosis is a known complication of TMVR, but determinants of increased post-procedure mean diastolic gradient are not well defined. Purpose We aimed to investigate the determinants of increased mitral...
