History and symptoms

Usually asymptomatic or may present with symptoms of heart failure, lower extremity clubbing, dyspnea. Depending on the size of the PDA, a cardiac murmur can be missed during the first physical exam of the newborn, because of the high pulmonary pressure that avoids the left-to-right shunt at that time. When the pulmonary pressure drops, the murmur is evident.
