title: Staged rehabilitation of ductal origin of the left pulmonary artery in an infant Fallot's tetralogy.
abstract: Isolation of a branch pulmonary artery from ductal closure is an unusual finding in patients with tetralogy of Fallot. A case report of a newborn is presented where the closing arterial duct was balloon-dilated and stented to reestablish blood supply to the affected lung as a strategy of improving systemic saturations and promoting the growth of the hiliar branch pulmonary artery. Five months after the initial palliation, complete surgical repair with stent removal was successfully achieved.
