title: [Causes of decreased stability of good survival results and the incidence of complications in patients with multiple heart valve prostheses].
abstract: The results of six-year follow-up of 368 patients after multiple prosthetic valve implantation (mitral and aortic prostheses in 173, mitral and tricuspid prostheses in 129, three prostheses in 36, mitral and aortic prostheses with tricuspid annuloplasty in 30) are reviewed. The mean functional class was 4.05 prior to the operation, and eventually declined to 2.1, being indicative of increased physical activity of the patients. Good results were stabilized in 61% of cases. Major causes of insufficient stability of good results were specific complications and progressive attendant heart diseases. There were no specific complications in 51% of the patients. The survival rate was 39.2%, including the intraoperative mortality rate. Long-term survival rate was 59.3%. Myocardial insufficiency, mostly occurring in patients with aortic prostheses and preoperative functional class 4 or 5, was one of the leading causes of reduced long-term survival. Therefore, patients should undergo surgery when in functional class 3, and those with aortic defects, while they are in functional class 2.
