Coarctation of the aorta in the syndrome of absent pulmonary valve with ventricular septal defect.

The case of a male child is reported in which the syndrome of absent pulmonary valve and ventricular septal defect was associated with anomalous drainage of the right superior pulmonary vein into the superior vena cava, atrial septal defect, a right aortic arch, and an aortic isthmic coarctation. The combination of aortic coarctation with a high degree of right-ventricular outflow obstruction has not been reported so far in the literature. This case shows that there is no proof of aplasia of the ductus arteriosus in the syndrome of absent pulmonary valve and ventricular septal defect. Most likely, there is an early involution of the ductus arteriosus; persistence of the ductus arteriosus would not be compatible with fetal survival.
