[An experience of successful valve repair for acquired mitral and tricuspid regurgitation in dextrocardia, situs inversus, bilateral vena cava, and hemiazygos continuation].

A 56-year-old woman was admitted to our department because of congestive heart failure. Chest X-ray showed dextrocardia with situs inversus. The echocardiography revealed severe mitral regurgitation due to prolapse of posterior leaflet and secondary Venography demonstrated the bilateral superior vena cava, huge coronary sinus and hemiazygos continuation with hypoplastic inferior vena cava. Mitral valve regurgitation was repaired by Carpentier's and Burr's technique, and tricuspid valve regurgitation was repaired by Kay's technique. Her postoperative course was uneventful. Valve surgery for acquired valvular lesion in dextrocardia with situs inversus is rare. Although valve repair is easily performed even in mirror-image heart as well as in normal, levo-position heart, preoperative evaluation of systemic venous return is important in the case of dextrocardia with systemic venous anomalies.
