Abstract
From July 26, 1978, through June 30, 1981, 240 patients were performed for replacement of tripple valves, double valves, aortic, and mitral valve, utilizing 266 S. J. M. Valves.
Of the 240 patients in the study, 16 died in the first 30 days after operation (6.7%).
The most cases of thromboembolic events ocurred within three weeks after operation.
Thromboemblic events at the 36 month interval for Aortic & Mitral valve replacement was 9.39%/patient years, for AVR 2.17%/patient years, for MVR 4.28%/patient years, and total cases 3.38%/patient years.
Valve malfunction occurred in one valve implanted in the tricuspid position. The cause of thrombosed valve was considered because of the poor anticoagulation therapy.
We emphasize importance of anticoagulation therapy in the early post operative period.
