20 years’ durability of Carpentier-Edwards Perimount stented pericardial aortic valve
Aortic valve disease is the most common cardiac valve condition in developed countries, and its prevalence increases with patient age, especially due to calcified aortic stenosis . Although aortic valve replacement (AVR) remains the most effective treatment in the majority of cases for significant aortic stenosis as well as aortic regurgitation, few data are available for long-term surgical outcome. Perimount pericardial valves offer excellent hemodynamic function, and the present authors’ 10 year experience proved to be satisfactory when these valves were implanted in both the aortic and mitral positions [2, 3]. However, the long-term durability and performance of the valve remained questionable. The study aim was to evaluate long-term results of valve replacement for significant aortic valve disease, and long-term behavior of the aortic Perimount pericardial bioprosthesis, which the present authors have been implanting since 1984.
