A 53-year-old woman had dyspnea on effort since half a year previously and was categorized as NYHA II. She had suffered from chronic atrial fibrillation (AF) for three years. She had undergone aortic valve replacement using a Starr-Edwards ball valve (SEV) for aortic regurgitation and mitral commissurotomy for mitral stenosis 29 years previously. Echocardiography revealed mitral stenosis with an orifice area of 0.9 cm2 and neither dysfunction of the SEV nor abnormal findings on the valve itself. She underwent mitral valve replacement and left atrial maze procedure for AF. Because of the intraoperative findings of the cloth wear-covered SEV cage, redo aortic valve replacement was performed simultaneously. St. jude Medical valves were used for valve prostheses. There was no complication and the ECG returned to sinus rhythm postoperatively. These has been no report of a patient with such a long period between SEV implantation and replacement in Japan. This experience made us realize again the importance of attention to the cloth wear covered cage during long term follow up for SEV.
