[SURGICAL TREATMENT OF THE ACQUIRED HEART FAILURES, USING BIOLOGICAL PROSTHESES]
Abstract:
Possibilities of application of bioprostheses for correction of acquired heart failures in condition of artificial blood circulation were studied. Examination and treatment of 235 patients, suffering failures of mitral valve (MV) and aortal valve (AV), was performed. In 89 patients a MV prosthesis was made, and in 146 — the AV prosthesis. In 94 patients bioprostheses were applied, and in 141 — mechanical prosthesis was implanted. Indices of the left heart portions morphometry and of survival, stability of good postop* erative results in remote period have witnessed high efficacy of the bioprostheses application and expediency of their application in the aged patients.
