[Surgical treatment of mitral stenosis].

Open and closed methods of mitral commissurotomy are appraised in comparison. Open correction of mitral stenosis was performed under conditions of extracorporeal circulation, closed correction was accomplished by the instrumental method from right and left approaches. The advantages of open mitral commissurotomy in complicated forms of the disease (intraatrial) thrombosis, calcinosis, restenosis, concomitant regurgitation) are demonstrated. The indications for both methods of surgical treatment are substantiated and recommendations for their effective application are given.
