International audienceBACKGROUND: We evaluate the clinical results of the Carpentier-Edwards supraannular (CE SAV) aortic bioprosthesis at long-term follow-up (over 25 years). METHODS: Between 1983 and 1994, 1,002 CE SAV prostheses were implanted. Data were prospectively collected, retrospectively analyzed, and stratified by age groups at the time of surgery (group 1, ≤60 years; group 2, 61 to 70 years; group 3, >70 years), using both the actuarial and the "actual" (cumulative risk) methods. RESULTS: The operative mortality was 11.3% (valve-related in 2 cases). Follow-up included 8,164.09 patient-years (average 13.7±6.6 years, up to 26.9 years). Overall survival at 25 years was significantly higher in group 1 (p<0.001). Freedom from structu...
