OBJECTIVES: The clinical results of Carpentier-Edwards standard bioprosthesis have been extensively studied for valvular heart surgery in America and Europe. However, the data of long-term performance of Carpentier-Edwards standard porcine valve in areas with a high prevalence of @entity6331 are still lacking. In this study, we assessed the clinical performance of Carpentier-Edwards standard porcine bioprostheses in a @entity1 group with high prevalence of @entity6331 . METHODS: A total of 872 @entity1 underwent valvular heart surgery with Carpentier-Edwards standard porcine bioprostheses replacement between 1975 and 1999 and the results were analyzed. Rheumatic etiology counts for 95% of the @entity1 . Mean age of operation was 40 +/- 14 years (mitral valve), 43 +/- 19 years (aortic valve), and 45 +/- 13 years (double valve). Follow-up was 95.6% complete and continued up to 24 years (total 7017 @entity1 -years) with mean of 8.9 +/- 5.1 years. RESULTS: The operative mortality rate was 5.85%. Actuarial @entity1 survival rates after discharge at 5, 10, 15, and 20 years were 92.5%, 83.8%, 72.3%, and 35.8%, respectively. A total of 442 cases received reoperation due to failure of bioprostheses. The mean duration to @entity712 is 12.2 +/- 0.4 years. Actuarial estimate of freedom from @entity340 at 5, 10, 15, and 20 years were 96.3%, 63.7%, 24.4%, and 7.7%, respectively. CONCLUSION: The long-term result of Carpentier-Edwards standard bioprostheses in the present @entity1 group is satisfactory. However, freedom from @entity712 is lower than that of Western series. Younger age at operation and higher prevalence of rheumatic etiology in this area are possible causes.
