The Björk-Shiley mechanical valve was the first tilting-disc valve used to replace aortic and mitral valves. We present a case of a double aortic and mitral valve replacement with both valves functioning properly over 48 years after the original implantation. Minimal negative changes are evident in either valve despite the progression of cardiac abnormalities, including the development of a dilated cardiomyopathy associated with chronic systolic and diastolic heart failure and the implantation of an implantable cardioverter defibrillator (ICD). Our patient's case appears to be the most significant example of double-valve replacement longevity described in the literature.
比约克-希利机械瓣膜是首个用于置换主动脉瓣和二尖瓣的倾斜盘式瓣膜。我们报告一例双主动脉瓣和二尖瓣置换病例，自最初植入后48年，两个瓣膜均功能正常。尽管存在心脏异常进展，包括与慢性收缩期和舒张期心力衰竭相关的扩张型心肌病的发展以及植入式心律转复除颤器（ICD）的植入，但两个瓣膜的负面变化都极小。我们患者的病例似乎是文献中描述的双瓣膜置换长期存活的最显著例子。
