The pathophysiological consequences depend on the size of the defect and the pulmonary vascular resistance.Patent<unk>  arteriosus is a heart condition that is normal but reverses soon after birth. In a persistent PDA, there is an irregular transmission of blood between two of the most important arteries (aorta and pulmonary artery) in close proximity to the heart. Although the<unk>  arteriosus normally seals off within a few days, in PDA, the newborn's<unk>  arteriosus does not close, but remains<unk> .
