Abstract:BACKGROUND: There are little comparative data on Carpentier-Edwards supraannular and pericardial second-generation bioprostheses. The aim of this work was to compare their hemodynamic and clinical outcomes in patients with aortic stenosis. METHODS: We conducted a retrospective study including 150 patients operated on for aortic stenosis between 1989 and 1993. Patients undergoing aortic valve replacement with either a Carpentier-Edwards supraannular or pericardial prosthesis were matched for sex (49% male), age (72 +/- 8 years), body surface area, valve size, associated procedures, and left ventricular ejection fraction. RESULTS: Mean follow-up was 6.5 +/- 3.3 years, giving a total follow-up of 983 patient-years. Thirty-day mortality and 10-year actuarial survival were, respectively, 8% and 51% in the supraannular group and 6.7% and 43.4% in the pericardial group. At 10 years, freedom from thromboembolism, structural failure, and all valve-related events were, respectively, 88.7%, 88.9%, and 68.7% in the supraannular group and 85%, 100%, and 82.2% in the pericardial group. There were four (5.3%) structural failures, and four (5.3%) reoperations for degeneration (n = 3) and endocarditis (n = 1) in the supraannular group. Freedom from structural dysfunction or reoperation was 87.3% in the supraannular group and 100% (p < 0.05) in the pericardial group. Echocardiographic review of 62 of 76 survivors (81.5%) demonstrated a trend toward a better hemodynamic profile of pericardial valves at the end of follow-up. CONCLUSIONS: Ten years after aortic valve replacement for aortic stenosis, Carpentier-Edwards pericardial prostheses give comparable and probably better results than Carpentier-Edwards supraannular prostheses.
