A total of 533 operations for recurrent mitral stenosis have been performed since 1987. Two hundred and twenty-six patients were operated on under extracorporeal circulation. Indications for open correction of the abnormality as an alternative to transventricular commissurotomy were defined by echocardiographic studies. In 86 patients, mitral restenosis was accompanied by involvement of other valves: aortic, tricuspid. Mitral prosthesis was required in 216 cases. Valve-preserving operations were made in 10 cases. The hospital mortality was 12.8%, it decreased from 17.5 for the first 126 operations to 7% for the last 100 operations. In isolated restenosis, the hospital mortality rate was 7.8%, it has reduced by 1.8% in the past 2 years. The hospital mortality was 2.4% for 327 transventricular recommissurotomies. There were 20.9% fatal outcomes in restenosis concurrent with other valvular diseases. In mitral-tricuspid stenosis, deaths reduced from 23.8% to 9.5%. The mortality rates decreased from 35.7 to 15.4% in mitral-aortic stenosis and from 33.3% to 18.2% in tricuspid stenosis. High mortality rates in restenosis concurrent with involvement of other valves are mainly related to the baseline status of the patients operated on.
自1987年以来，共进行了533例复发性二尖瓣狭窄手术。226例患者在体外循环下接受手术。超声心动图研究确定了开放矫正该异常作为经心室交界切开术替代方法的适应症。86例患者的二尖瓣再狭窄伴有其他瓣膜（主动脉瓣、三尖瓣）受累。216例病例需要二尖瓣置换。10例进行了保留瓣膜手术。医院死亡率为12.8%，从最初126例手术的17.5%降至最后100例手术的7%。在单纯再狭窄中，医院死亡率为7.8%，在过去2年中降低了1.8%。327例经心室交界再切开术的医院死亡率为2.4%。再狭窄合并其他瓣膜疾病的致命结局发生率为20.9%。在二尖瓣-三尖瓣狭窄中，死亡率从23.8%降至9.5%。二尖瓣-主动脉瓣狭窄的死亡率从35.7%降至15.4%，三尖瓣狭窄的死亡率从33.3%降至18.2%。再狭窄合并其他瓣膜受累的高死亡率主要与接受手术患者的基线状况有关。
