title: Cicatricial changes in a Ionescu-Shiley bioprosthesis.
abstract: The mitral Ionescu-Shiley standard-profile prosthesis of a 53-year-old woman who had it placed 12 years previously is described. The observed cicatricial retraction of one of the bioprosthesis' cusps is unusual, and it contributed to the bioprosthetic dysfunction which necessitated this valve's replacement.
