[Remote results of the correction of mitral valve defects with aortic xenobioprosthesis].

An analysis of the 6-year observations of 84 patients with aortal xenobioprosthesis in the mitral position has shown the bioprostheses to give an adequate and stable correction of hemodynamics, low risk of thromboembolic complications. The anticoagulation therapy was found to be not necessary in most of the patients. The aortal xenobioprostheses in patients older than 20 gave high survival rate (93%) and low risk of specific complications (5,4%). However, great amount of complications in young patients (58%) shows them to be used but for strict indications.
