Functional mitral regurgitation (FMR) accompanying nonischemic dilated cardiomyopathy (DCM) has a poor prognosis, and its surgical management is still controversial. We report a novel surgical approach that consists of the repair of papillary muscle geometry and annuloplasty with a semirigid ring and partial resection of the dilated left ventricle (LV). Mid-term postoperative results of our surgical approach included no recurrence of FMR, effective reduction of the LV volume and shape, and improvement of pulmonary artery pressure.

Clinical Summary

A 42-year-old man was admitted to our center for an easy fatigability on effort. On admission, echocardiogram demonstrated a dilated LV associated with severe mitral valve regurgitation. End-systolic volume index (ESVI) and end-diastolic volume index (EDVI) were 139.5 and 160.5 mL/m2, respectively. Although severe regurgitation was present either at the mitral (3+) or tricuspid valve (3+), ejection fraction (EF) was decreased to 13 percentages, and pulmonary artery systolic pressure (PAP) was increased to 39 mm Hg. Preoperative gated single photon emission computed tomography quantification confirmed the diagnosis of DCM and showed the spherical shape of the dilated LV. Coronary angiography showed normal coronary . . . [Full Text of this Article]
