We describe the case of a 15-year-old boy with complex heart disease, in whom we successfully performed bivalvation for common atrioventricular valve regurgitation and bilateral, bidirectional cavopulmonary shunts. Postoperative Doppler echocardiography revealed significant reduction of atrioventricular valve regurgitation.
