[The results of the surgical treatment of recurrent mitral stenosis under artificial circulation].
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.
