[Surgical treatment of mitral valve stenosis under conditions of artificial circulation].

The problem of a surgical management of rheumatic mitral stenosis in open-heart procedures under extracorporeal circulation is discussed. The experience of 240 surgical corrections is presented: 139 open mitral commissurotomies, 101 prosthetic replacements of the mitral valve. The current status of the problem is discussed along with the problems of diagnosis, complications of mitral stenosis, and open-heart technique of surgery. On the basis of the obtained results the advantages of the open correction of complicated forms of mitral stenosis over the closed techniques are demonstrated.
