title: The Carpentier-Edwards pericardial bioprosthesis: clinical experience with 600 patients.
abstract: Carpentier-Edwards pericardial bioprostheses were implanted in 600 patients: 416 aortic valve replacement, 115 mitral valve replacement, 6 isolated tricuspid, and 63 multiple valve replacements. The survival rates were 70% at 10 years after aortic valve replacement, 62% 8 years after mitral valve replacement, and 57% at 8 years with multiple valve replacement. Overall, 69 patients suffered one or more valve-related complications. The 10-year freedom rates from embolism were 91% (aortic valve replacement), 92% (mitral valve replacement), and 89% (multiple valve replacement), and those from endocarditis were 95%, 93%, and 85%, respectively. In 18 of the 35 patients, reoperation was due to primary valve dysfunction. Freedom from primary dysfunction was 87% at 10 years with aortic valve replacement, and at 8 years, it was 79% with mitral valve replacement and 77% with multiple valve replacement. A direct correlation was found between freedom from valve dysfunction and age of the patient at operation, with a 10-year-free rate of 90% among patients older than 59 years. This bioprosthesis has an excellent durability up to 10 years in the aortic position. More data regarding its long-term durability in the mitral position are needed. It is currently our valve substitute of choice when a bioprosthesis is indicated.
