Use of prostaglandin E1 in infants with d-transposition of the great arteries and intact ventricular septum

Abstract

Prostaglandin E1 was used to treat five infants with d-transposition of the great arteries and intact ventricular septum who had persistent severe hypoxemia after the creation of an interatrial communication. Three infants had a dramatic improvement in systemic arterial oxygen saturation associated with dilation of the ductus arteriosus; in two of the three cases urgent surgery was avoided. Two infants had no clinical evidence of increased ductal shunting and no improvement in oxygen saturation. A trial of prostaglandin E1 is recommended for treatment of severe hypoxemia in infants with d-transposition of the great arteries with intact ventricular septum if the presence of a large atrial septal defect is established.
