[Cardiac insufficiency and mortality after correction of the mitral valve defect, depending on the degree of cardiac output before the operation].
The course of the postoperative period was studied in 107 patients subjected to adequate correction of mitral valvular disease; 88 of them underwent open heart surgery. The cardiac output was measured by radiocardiography. Total postoperative mortality was 13%, cardiac insufficiency mortality 8.4%. Cardiac insufficiency was encountered in 42% of patients who had been operated on. Significant increase in the rate of cardiac insufficiency with the diminution of the cardiac index with "critical" value of 21/min/m2 was established: cardiac insufficiency was found in 76.3% of patients subjected to operation with cardiac index below 21/min/m2 and in 23.2% among those with cardiac index equal to or more than 21/min/m2. A similar regularity was revealed in analysis of cardiac insufficiency mortality:with cardiac index below 21/min/m2 it was 18.4%, with cardiac index of 21/min/m2 or more, it was 2.9%. No interrelationship was revealed between cardiac insufficiency incidence and mortality and the type of mitral valve lesion, extent of surgical intervention, and duration of extracorporeal circulation.
