This patient is a 72-year-old-man who had undergone aortic valve replacement using a Starr-Edwards Ball Valve to treat aortic valve stenosis when he was 28 years old. In April 2015, he was admitted with cardiac failure of NYHA III. Echocardiography showed a remarkable increase of aortic valve pressure gradient and progressive change in mitral valve stenosis and tricuspid valve regurgitation. The Starr-Edwards Ball Valve was replaced using a CEP MAGNA EASE prosthesis, the mitral valve was replaced using a CEP MAGNA MITRAL EASE prosthesis with tricuspid annuloplasty using the MC3 ring. Cloth wear of the Starr-Edwards Ball Valve cage and all-round pannus formation under the valve seat was found at the operation, and the cause of the higher pressure gradient may have been the pannus. The postoperative period of this case following the initial aortic valve implantation of the Starr-Edwards Ball Valve is the longest known in Japan as far as we could discover.
