Successful Valve Prolapse Repair for Ischemic Mitral Regurgitation: Combined Papillary Muscle Approximation and Mitral Chordae System Replacement.

Mitral valve prolapse occurs in 33.6% of patients undergoing surgery for ischemic mitral regurgitation (IMR). In the context of IMR, reparative strategy cannot disregard the underlying mechanism of pathogenesis and the progressive geometric alteration affecting left ventricle and papillary muscles. We present a case of extended mitral prolapse of the posteromedial commissure and A3 concomitant to chordal injury after inferior myocardial infarction. We propose a combined sequential approach including papillary muscle approximation and a mitral chordae system replacement.
