A 50-year-old man was referred to our hospital with a tumor in the left ventricle. He had suffered from rheumatic fever when 14 years old. He had shown signs of chronic heart failure due to atrial fibrillation and rheumatic valves (ASr, MSr) for 10 years. There was a history of unaccountable fever and rash, so infective endocarditis was suspected and echocardiography was performed. It showed a homogeneous mass with a diameter of approximately 10mm, fixed directly to the left ventricular septum 20mm below the aortic valvular ring. At operation, the tumor was excised together with endocardium and a part of the muscular coat. The rheumatic aortic and mitral valves were replaced with a 21mm SJM AHP and a 27mm SJM MTK mitral valve, respectively. Tricuspid annuloplasty (TAP) (De Vega 29mm) was also performed. Histopathological examination of the tumor revealed benign papillary fibroelastoma. It suggested that the tumors were secondary to mechanical wear and tear, and represent a degenerative process due to rheumatic valve disease.
