Structural valve deterioration of a mitral Carpentier-Edwards pericardial bioprosthesis in an 87-year-old woman 16 years after its implantation.

The second-generation pericardial valve, the Carpentier-Edwards perimount bioprosthetic (CEP) valve, shows dramatically improved durability as compared to the first-generation pericardial valve, and excellent performance has been obtained, in both the aortic and mitral positions. Especially in elderly patients with an implanted CEP valve, reoperation due to structural valve deterioration (SVD) is rarely required. Here, we report the case of an 87-year-old woman with an explanted CEP valve in the mitral position due to SVD, 16 years after its implantation.
