ABSTRACT
Objective:
To evaluate the long-term result after bioprosthesis replacement, and analyse the risk factors of the late deaths.Methods:
From September 1984 to March 1988, 90 patients underwent bioprosthesis replacement in our hospital. There were 39 males (43%) and 51 females (57%) with an average age of 36.1 years. 78 patients had rheumatic disease, 8 degenerative disease, 3 congenital mitral valve anomaly and 1 Ebstein's anomaly. The preoperatively heart function (NYHA) was grade II in 15, grade III in 54, and grade IV in 21. C/T was 0.51~0.90 (average 0.65?0.10).Results:
The operative mortality rate was 7。8%. All survived patients were followed up. The mean follow-up time was 7.8 years (range from 3 months to 15.7 years. 35 patients died during the follow-up period. The causes of death cardiac related deaths in 33 patients (88.6%), noncardiac related death in 3 (8.6%), and unknown in 1 (2.8%). Reoperation was performed in 20patients. At 1, 5 and 10 years after operation, the actuarial survival rate of patients were 92.7%, 80.7% and 57.8%, respectively. Multiple regression analysis showed that preoperatively cardiac function, C/T ratio and EF were risk factors for late deaths.Conclusion:
The long-term results with bioprosthesis replacement appear satisfactory.
