Patent ductus arteriosus (PDA) is a congenital disorder in the heart wherein a neonate’s ductus arteriosus fails to close after birth. Early symptoms are uncommon but in the first year of life include increased work of breathing and poor weight gain. With age the PDA may lead to congestive heart failure if left uncorrected. The ductus arteriosus is a normal fetal blood vessel that closes soon after birth.
