In brief: Fetal structure
A patent ductus arteriosus (pda) is a small vessel that connects the pulmonary artery to the aorta during fetal life.
Once the umbilical cord is cut and we are exposed to an oxygen rich environment that vessel should "shrivel up" and become an unobtrusive ligament. In some people it never closes and in some it will need to be addressed.
