OBJECTIVES: Aortic valve replacement (AVR) using a bioprosthesis remains controversial for patients aged 50-65 years. This cohort study reports the very long-term outcomes of AVR using Carpentier-Edwards Perimount pericardial bioprosthesis in this age group. METHODS: From 1984 to 2008, 522 Carpentier-Edwards Perimount pericardial aortic bioprostheses were implanted in 516 patients aged 50-65 years (mean age, 60 ± 4 years; 19% female). Multiple valve replacements were excluded fro m our cohort. Baseline demographic, perioperative and follow-up data were recorded prospectively. Mean follow-up was 9 ± 6 years, for a total of 4428 valve-years. Follow-up was complete for 97% of patients included. RESULTS: Operative mortality rate was 2%. One hundred and forty-six late deaths occurred for a linearized rate of 3%/valve-year. Actuarial survival rates averaged 73 ± 2, 59 ± 3 and 35 ± 5% after 10, 15 and 20 years of follow-up, respectively. Mortality rate associated with reoperation was 2%. Actuarial freedom from reoperation rates due to structural valve deterioration (SVD) at 10, 15 and 20 years was respectively of 91 ± 2, 76 ± 3 and 50 ± 6%. Competing risk analysis demonstrated an actual risk of explantation secondary to SVD at 20 years of 30 ± 3%. Expected valve durability was 19 years for this age group. Age was not a significant risk factor for SVD in this middle-aged population. CONCLUSIONS: In patients aged 50-65 years undergoing AVR with the Carpentier-Edwards Perimount bioprosthesis, the expected valve durability was 19 years. Age was not a significant risk factor for SVD within this age group. Patient selection and attention to timing of reintervention may be determinants of long-term outcomes.
