Patent ductus arteriosus

PDA

Patent ductus arteriosus (PDA) is a condition in which the ductus arteriosus does not close. The word "patent" means open.

The ductus arteriosus is a blood vessel that allows blood to go around the baby's lungs before birth. Soon after the infant is born and the lungs fill with air, the ductus arteriosus is no longer needed. It most often closes in a couple of days after birth. If the vessel doesn't close, it is referred to as a PDA.

PDA leads to abnormal blood flow between the 2 major blood vessels that carry blood from the heart to the lungs and to the rest of the body.
