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.
描述了一名53岁女性的二尖瓣Ionescu-Shiley标准型人工瓣膜，该瓣膜于12年前植入。观察到生物瓣膜的一个尖瓣出现瘢痕性回缩，这种情况并不常见，它导致了生物瓣膜功能障碍，因此需要更换该瓣膜。
