A 71-year-old woman was admitted to our hospital presenting right heart failure. She had undergone mitral valve replacement and concomitant tricuspid valve replacement 7 years before the admission. Computed tomography at the time of the first operation revealed enlargement of the coronary sinus of 3.8 cm with a persistent left superior vena cava. On the latest admission, a transesophageal echocardiogram revealed prosthetic valve failure on the tricuspid valve position. Computed tomography showed giant coronary sinus with a maximum diameter of 6.2 cm. Retricuspid valve replacements was successfully performed. Severe pannus formation and adhesion of native valves were observed on the right ventricular side of the prosthetic valve. This is the first report describing aneurysmal growth of a coronary sinus caused by a prosthetic valve failure.
