Abstract
Surgical restoration of subvalvular geometry is very important to prevent recurrence of ischemic/functional mitral regurgitation. We evaluated an approach to the radical repair of left ventricular (LV) remodeling for three different cases with responsible coronary lesions. Leaflet tethering was corrected by tugging of the papillary-ventricular complex, which consists of the base of papillary muscles and posterior LV wall. The main lesion of the postinfarction scar was concomitantly excluded. Restoration of LV remodeling diminished mitral regurgitation with minimal leaflet tethering and improved systolic LV function. This technique may be an aggressive and encouraged approach for patients with ischemic/functional mitral regurgitation.
