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.
对107例接受二尖瓣疾病充分矫正的患者的术后病程进行了研究；其中88例接受了心脏直视手术。通过放射性心动图测量心输出量。术后总死亡率为13%，心功能不全死亡率为8.4%。42%接受手术的患者出现了心功能不全。随着心脏指数降至“临界”值21/分钟/平方米，心功能不全发生率显著增加：心脏指数低于21/分钟/平方米的手术患者中，76.3%出现心功能不全，而心脏指数等于或高于21/分钟/平方米的患者中，这一比例为23.2%。在心功能不全死亡率分析中也发现了类似规律：心脏指数低于21/分钟/平方米时，死亡率为18.4%，心脏指数为21/分钟/平方米或更高时，死亡率为2.9%。未发现心功能不全发生率和死亡率与二尖瓣病变类型、手术干预范围及体外循环持续时间之间存在相互关系。
