[Hemodynamic results of replacing the mitral valve with an aortic xenobioprosthesis].

Results of an analysis of clinico-hemodynamic data obtained in 66 patients with bioprosthesis of the mitral valve are presented. The data of intraoperative examination as well as of catheterization of heart cavities within the period from 6 to 62 months after operation show the xenoaortic bioprosthesis to give an adequate correction of the mitral valve defect, their implantation was followed by a substantial improvement of the patients's state.
