The article presents indications to surgical correction of aortal stenosis and its variants in patients with rheumatic diseases combined with a lesion of other valves of the heart. The possibility to fulfill valve-saving plastic operations on the stenosed aortal valve was shown in 110 operations. The results obtained proved advantages of plastic operations over prostheses of the stenosed aortas without calcinosis universalis. Such operations allowed the intrahospital lethality to be considerably decreased. In later terms only two patients needed prostheses of the valve. The functional class was improved in the overwhelming majority of the patients.
