Abstract

From a total of 1152 consecutive patients with heart valve replacement (1964-87) 108 patients (9.4%) had to be reoperated. Mechanical valves had to be replaced (n = 89) mainly because of perivalvular leakage, followed by prosthetic stenosis and dysfunction. The lowest reoperation rate was found with Bjork-Shiley prostheses (3.4%). Bioprostheses (reoperation rate 8.2%) had to be reoperated predominantly as a consequence of dysfunction. Ten years following implantation 30% of bioprostheses had to be replaced. Patients with reoperations demonstrated, in comparison to patients with singular valve replacement, no significant change in early mortality during the last 6 years (6.8% vs 5.4%). Furthermore, both patient groups revealed similar survival rates (10 years: 78% vs 76%) and improvement of life quality. However, non-letal peri- and postoperative complication rates were higher in reoperated patients compared to patients with first valve replacement.
