title: [Results of prosthetic heart valve replacement. Primary, secondary and emergency operations].
abstract: From 1962 to 1984, 2460 prosthetic valve implantations in the heart were performed at the Department of Surgery of the University of Heidelberg. In addition to 2291 primary surgical interventions, 169 re-interventions were carried out. 153 emergency operations were necessary. The frequency rate of operations increased continuously; 52% of the operations were performed at the aortic valve and 37% at the mitral valve. In 9% of the cases, two valves had to be replaced, and in 2% even three valve prostheses were implanted. The indications for re-intervention included prosthetic thromboses, paravalvular leakages and prosthetic valve endocarditis. The situations requiring emergency intervention differed from case to case. Early mortality, which had been initially high, could be considerably reduced due to increased experience in surgical technique, anaesthesia, intensive care and improved myocardial protection. The extent and quality of medical postoperative care will determine the success of medical rehabilitation and hence the future professional activity of the patient.
