Spontaneous Closure of Ventricular Septal Defect following Pulmonary Artery Banding

Spontaneous closure of large ventricular septal defects is uncommon, and only four such closures have been described following pulmonary artery banding. Two additional cases are reported. Despite frequent closure of ventricular septal defects in general, closure of large defects that cause intractable heart failure in infancy is uncommon, and its anticipation should not alter their management.
