Abstract

We reviewed the clinical and hemodynamic studies in 10 patients with the isolated congenital mitral insufficiency. The patients ranged in age from 6 months to 16 years at the time of diagnosis and the incidence was 0.26% among the total congenital heart disease proven by cardiac catheterization and angiography. In two cases anterior mitral cleft was demonstrated by 2-D echocardiography and/or operation. In two cases left coronary artery was originated from pulmonary artery. Eight cases out of ten presented symptoms indicating varying degrees of left ventricular failure. Apical systolic murmur was heard in all except one, who had only triple rhythm. The electrocardiograms revealed left ventricular hypertrophy in 8 cases and biventricular hypertrophy in 2 cases. Roentgenographically left atrial enlargement was observed in 4 cases. Left arterial and ventricular dimension were increased in 7 cases by echocardiography. In 5 cases of them, pulmonary artery wedge pressure or left atrial pressure was increased. One patient died in congestive heart failure at the age of 10 months and one patient died postoperatively. Other 4 patients have been managed with medication without difficulty.
