A 73-year-old woman with congenital isolated organic tricuspid regurgitation was reported. She had neither the history of chest trauma nor rheumatic fever nor the evidence of infective endocarditis. The patient was successfully treated with a bioprosthetic valve replacement in tricuspid position. Operative findings revealed hypoplastic anterior leaflet and relatively large posterior leaflet. Structural anomaly of the valve, coaptation disorder due to the thickened valve leaflets, as well as enlarged valve ring and the occurrence of atrial fibrillation was thought to be the causes of massive regurgitation.
