Correction of type B interrupted aortic arch with ventricllar septal defect in infancy.
The successful correction of a Type B interrupted aortic arch (IAA) with simultaneous closure of a ventricular septal defect (VSD) in a 6-month-old infant is described. With the use of profound hypothermia and limited cardiopulmonary bypass, a flap of pulmonary artery, together with the persistent ductus arteriosus (PDA), was dissected free and sutured so as to form a tube which then was anastomosed to the ascending aorta. The ventricular septal defect and the pulmonary arteriotomy then were closed. Cardiac catheterization 5 months later demonstrated a satisfactory reconstruction with no gradient between the ascending and descending aorta.
