Patency of the ductus arteriosus is critical in maintaining fetal circulation, and premature closure is associated with fetal and early neonatal death. We present 2 cases of sudden demise in the delivery room associated with atypical ductal anatomy with obstruction due to kinking and intraluminal intimal ridges. Shepherd hook anomaly of the ductus arteriosus may represent a new congenital heart lesion associated with poor fetal outcome.
