Abstract
An 11-month-old girl was transferred for consideration of cardiac transplantation. She had previously undergone repair of complete atrioventricular septal defect at another institution. Her postoperative course was notable for severe mitral regurgitation, pulmonary hypertension, and heart failure. At reoperation, the left atrioventricular valve was considered irreparable with a very small (11 mm) annulus. Using a technique to enlarge the mitral annulus, a 17-mm prosthetic valve was placed. Her postoperative course was unremarkable and she is doing very well at 3 years follow-up.
