Abstract

We assessed postoperative functional recovery of the left ventricle (LV) in 27 patients with pure mitral regurgitation (MR). The patients were divided into three groups according to the preoperative left ventricular end-systolic volume index (LVESVI) : Group I (LVESVI≧100 ml/m^2) included 7 patients, Group IIR (LVESVI<100 ml/m^2, mitral valve replacement (MVR) was performed) included 10 patients, and Group IIP (LVESVI<100, mitral valve plasty (MVP) was performed) included 10 patients. By means of two-dimensional echocardiography, left ventricular diastolic dimension (LVDd), systolic dimension (LVDs), and fractional shortening (FS) were evaluated before and one month after operation. In Group I, LV function showed a remarkable decrease befor...
