    Abstract:
    From March, 1982, through March, 1988, 8 infants less than 3 months of age underwent surgical treatment of interrupted aortic arch. Five patients had IAA type A and 3 patients had type B. Seven patients with associated VSD underwent staged operations and 1 infant with aortopulmonary window underwent primary repair off cardiopulmonary bypass. Aortic arch reconstruction was by subclavian aortic anastomosis (6) or large tube graft (8 mm) interposition (2) combined with pulmonary artery banding (5). All seven patients with associated VSD survived the first-stage operation. One patient subsequently underwent pulmonary artery banding, two underwent patch aortoplasty and four patients underwent intracardiac repair and removal of a pulmonary artery band, with six survivors (86%). The operative death occurred in an infant in whom modified Damus-Kaye-Stansel operation was carried out for severe subaortic stenosis, which rerouting all left ventricular blood through VSD and the main pulmonary artery into the ascending aorta and reconstructing right ventricular-distal pulmonary artery connection by a valved external conduit. All six surviving patients are doing well at present (mean follow up of 3 years) without any significant pressure gradient between the ascending and thoracic aorta. Based on these data we conclude: (1) Aortic arch reconstruction and pulmonary artery banding can be reliably performed even in critically ill infants with IAA and isolated VSD. (2) The primary repair will provide better chance of survival in infants with IAA associated with significant LVOTO, truncus arteriosus or aortopulmonary window that do not readily lend themselves to pulmonary artery banding.
