Pulmonary atresia with intact ventricular septum coexisting with coarctation of the aorta.

A newborn with pulmonary atresia, intact ventricular septum, and a bicommissural aortic valve underwent percutaneous pulmonary valvotomy at 1 day of age. Severe coarctation of the aorta became apparent only after spontaneous closure of the ductus arteriosus at 5 weeks of age, requiring repair by surgical end-to-end anastomosis. This is the first report of a child with pulmonary atresia with intact ventricular septum in association with coarctation of the aorta.
