Patent Ductus Arteriosus (PDA)
Patent ductus arteriosus (PDA), which is more common in premature infants, is a condition in which the heart's ductus arteriosus doesn't close. The open passageway is either wide (a large PDA) or narrow (a small PDA). A large PDA is dangerous because blood flow to the lungs isn't as controlled as it should be, leading to problems with the lungs and heart.
