A 59-year-old male who had undergone aortic and mitral valve replacement with Starr- Edwards ball valves 27 years ago was admitted to our hospital for hemolytic anemia and heart failure. Echocardiography revealed prosthetic valve failure with a high-pressure gradient and small effective orifice area. The Starr-Edwards ball valves were successfully replaced with bileaflet mechanical valves. The explanted valves revealed no structural abnormalities.
