[Repeated operations on the heart in patients with a history of mitral commissurotomy].

The article analyzes the results of surgical treatment of 262 patients, with 160 of them having undergone closed mitral recommissurotomy. One hundred and two patients were operated on under conditions of assisted circulation. The conduction of repeated closed operations is justified in uncomplicated forms of mitral restenosis. In cases of marked calcinosis and regurgitation on the mitral valve, left atrial thrombosis and attended defects, surgery must be performed with extracorporeal circulation.
