[Long-term results after isolated aortic and mitral valve replacement with a prosthesis (author's transl)].

111 patients with aortic valve replacement (AVR) and 159 patients with mitral valve replacement (MVR) were studied after hospital discharge. The late mortality was 20% after AVR and 32% after MVR. Of the survivors, 93% were greatly improved after AVR and 83% after MVR (functional class I or II). The calculated 5-year survival rate of the patients with AVR is 76% and with MVR 64%. The general state of health of the survivors, the thromboembolic rate and the fatal complications are discussed. Further improvement in the results can only be expected if valve replacement is performed before irreversible myocardial damage has occurred.
