[Mitral Valve and Tricuspid Valve Regurgitation in a Patient with Dextrocardia and Absence of the Inferior Vena Cava].

Dextrocardia is a rare condition frequently associated with multiple and complex cardiovascular abnormalities. A 66-year-old woman, who had been diagnosed with dextrocardia at young age, was referred to our hospital with complaint of increasing dyspnea. Severe mitral regurgitation, moderate tricuspid regurgitation, and atrial fibrillation were detected. The multi detector-row computed tomography(MDCT) revealed absence of the inferior vena cava, and the hepatic vein connected directly with the right atrium. The venous cannulae were inserted into the superior vena cava directly and into the hepatic vein from the right atrium. Mitral valve repair, tricuspid valve repair, and maze procedure were successfully performed. MDCT is useful for detecting abnormality of vena cava in a cases of dextrocardia.
