title: Unbalanced atrioventricular septal defect with parachute valve.
abstract: A 5-month-old male patient presented with right-dominant unbalanced atrioventricular septal defect and left-sided parachute valve, and underwent successful biventricular repair. Because of the presence of a small left ventricle, left atrium, and a single left papillary muscle, an additional orifice was created in the left-sided atrioventricular valve with artificial partitioning of the right-sided atrioventricular valve. There was no evidence of mitral stenosis or regurgitation on follow-up echocardiography.
