Severe mitral regurgitation in patients with postinfarction interventricular septal defect: a simple way of simultaneous valve repair.

Abstract

Ventricular septal defect, a potentially deadly complication of transmural myocardial infarction, is often accompanied by ischaemic mitral regurgitation. It has been recognized that the presence and persistence of the latter negatively affect survival rates in patients after myocardial infarction. We present a simple endoventricular edge-to-edge technique of mitral repair using a single U-shaped stitch of polytetrafluoroethylene and a refined double-patch 'exclusion' technique of postinfarction interventricular septal defect (PVSD) closure in the treatment of two consecutive cases of PVSD and concomitant ischaemic mitral regurgitation. This technique is effective and reproducible to address mitral incompetence in patients undergoing surgical correction of PVSD.
