The results in 241 patients (131 aortic, 103 mitral, and 7 tricuspid valve operations) with replacement of heart valves by stented tissue valves were analyzed. Autologous fascia lata was used in 78 patients, homologous fascia lata in 65, and heterologous pericardium in 98 patients. The follow-up for the fascia lata group was 38 to 60 months and for the pericardium group 6 to 37 months. Valve function has differed significantly with regard to both the site of valve insertion and the type of tissue used. Aortic pericardial valves have produced the best results and autologous fascial valves in the mitral position the worst. Valve failure has occurred in only 6 patients with autologous fascia in the mitral position. Considerable symptomatic improvement was reported by the majority of patients with either aortic or mitral replacement. The incidence of thromboembolism in the entire series has been very low although anticoagulants were not used. Analysis of clinical and hemodynamic results and the assessment of valve function have shown that preserved heterologous pericardium has the potential qualities for a heart valve substitute. |
