This case demonstrates the remarkable long-term durability of the Starr-Edwards ball valve prosthesis, showing only lipid infiltration of the silastic ball after 28 years.
A 53-year-old woman who had undergone aortic valve replacement with a Starr-Edwards (S-E) valve (Model 1260) and open mitral commissurotomy 28 years previously was hospitalized with cardiac failure. Echocardiography showed mitral stenosis, mitral regurgitation, and a normally functioning S-E prosthesis. At reoperation, the mitral and aortic valves were replaced with St Jude bileaflet mechanical prostheses. Examination of the explanted S-E prosthesis revealed no structural abnormality other than lipid infiltration of the silastic ball.

Tayama et al. (2004) conducted a case report in Cardiac failure, mitral stenosis, and previous aortic valve replacement (n=1). Valve replacement with St Jude bileaflet mechanical prostheses was evaluated on Structural integrity of explanted valve and clinical recovery. Examination of an explanted Starr-Edwards aortic valve prosthesis 28 years after implantation revealed no structural abnormalities other than lipid infiltration of the silastic ball.
