valves were implanted in 28 patients and aortic valves were implanted in 18 patients. Follow up was 100% complete. With 345.6 patient-years and a mean follow up of 41 months(from 1.5 to 84 months). The total mortality was 14.9%(16 patients). The
early
mortality was 5.6%(6 patients) and the late mortality was 9.3%(10 patients). The overall actuarial survival was 92.6±2.6% at 2 years, 88.6±3.8% at 6 years.
The probability of freedom from valve failure, thromboembolism and bacterial endocarditis were 88.6±3.8, 88.3±3.9, 89.5±3.7 at 6 years, respectively.
