A 62-year-old woman was admitted to our hospital because of dextrocardia on her chest X-ray film. She had been in good health though the X-ray abnormality had been pointed out from her childhood. Echocardiogram, magnetic resonance imaging, and cardiac catheterization revealed situs inversus, congenitally corrected transposition of the great arteries, and severe tricuspid valve（systemic atrioventricular valve）regurgitation with mild systemic ventricular dysfunction. The surgeon stood on the patient’s left side during the operation. On cardiopulmonary bypass, the tricuspid valve, facing almost dorsally, was exposed through a superior transseptal approach. Tricuspid valve replacement with a mechanical valve was performed with leaflet preservation. Systemic ventricular function is preserved at one year after operation.
