This report describes the use of myocardial delayed-enhancement magnetic resonance imaging to delineate the extent of endocardial fibroelastosis (EFE) in 4 infants after fetal balloon aortic valvuloplasty. The preoperative mapping of EFE followed by extensive resection led to biventricular physiology in 2 patients.
