This case demonstrates the exceptional longevity of Björk-Shiley mechanical valves, functioning properly for 48 years in both aortic and mitral positions.
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.

McManus et al. (2023) conducted a case report in Rheumatic valvular disease (n=1). Björk-Shiley mechanical valve replacement (aortic and mitral) was evaluated on Valve functionality. A double-valve Björk-Shiley pyrolite carbon disc replacement maintained normal function for over 48 years in a single patient despite the development of dilated cardiomyopathy.
