Abstract
The ductus arteriosus is a fetal vascular connection between the main pulmonary artery and aorta that diverts blood away from the pulmonary bed. Left and right ductus arteriosi emerge from embryological aortic arches. In normal embryologic cardiac development, both right aortic and ductal arches regress and the left ones persist. Persistent right ductus arteriosus (rDA) is one of the congenital anomalies of the ductal arch. In this paper, we report three cases of persistent right ductus arteriosus with right aortic arch.
