Two-dimensional echocardiograms were recorded a mean 2.5 ± 2.0 weeks before and 6.5 ± 2.5 months after valve operation. Postoperative significant mitral regurgitation was present in 3 patients. After mitral valve repair there were significant decreases in left ventricular end-diastolic volume index (133 ± 39 mL/m2 to 79 ± 35 mL/m2; p < 0.001), end-systolic volume index (44 ± 26 mL/m2 to 30 ± 26 mL/m2; p < 0.001), stroke volume index (89 ± 29 mL/m2 to 49 ± 19 mL/m2; p < 0.001), and mass index (211 ± 82 g/m2 to 134 ± 52 g/m2; p < 0.001). There also were significant decreases in left atrial dimension (47 ± 9 mm to 38 ± 9 mm; p < 0.001), left ventricular end-diastolic dimension (61 ± 8 mm to 48 ± 7 mm; p < 0.001), and end-systolic dimension (39 ± 8 mm to 32 ± 7 mm; p < 0.001). Left ventricular ejection fraction decreased slightly from 0.69 ± 0.12 to 0.64 ± 0.12; p < 0.01) after repair. Thus, correction of pure mitral regurgitation leads to reduction of the cardiac chamber size and left ventricular volumes as well as regression of the left ventricular mass. |
