Patent ductus arteriosus is a congenital heart condition in which the ductus, a small opening or pathway between the pulmonary and aortic valves, remains open or patent. In most cases, the ductus closes within a day after birth. However, in patent ductus arteriosus, the ductus remains open, causing blood to mix between the two valves.
