Abstract
An infant boy with 21 trisomy was diagnosed with complete atrioventricular septal defect-Rastelli type A with parachute left atrioventricular valve and absent left mural leaflet. Biventricular repair was difficult in infancy because the left ventricular volume and left atrioventricular valve annulus were too small. After 2 pulmonary artery bandings, the left atrioventricular valve annulus increased to 85% of normal mitral valve, and the left ventricular end-diastolic volume increased to 98% of normal. We report a successful instance of complete atrioventricular septal defect that achieved biventricular repair via novel left atrioventricular valvuloplasty for parachute left atrioventricular valve and absent left mural leaflet.
