What Is Patent Ductus Arteriosus ?
Patent ductus arteriosus (PDA) is a Congenital defect in which the temporary blood vessel connecting the left pulmonary artery to the aorta in the fetal heart fails to close after birth. In the fetal heart, blood bypasses the lungs and gets oxygen from the placenta. But when the newborn's lungs take over at birth, the body stops producing the chemicals that keep the ductus arteriosus open, and it closes naturally.
If the ductus arteriosus fails to close completely, the baby has PDA. While this problem is rare, it is sometimes associated with mothers who have had German measles (rubella) during pregnancy and with infants born before their due date (prematurely). The result of this defect is that too much blood travels to the lungs. The severity of the problem depends on how large the opening is and how prematurely the baby was born.
