In this chapter only the anomalous origin of a pulmonary artery from the systemic circulation, without interposition of ductal tissue, is taken in consideration. The congenital vascular anomaly in which the left pulmonary artery originates from the right pulmonary artery or pulmonary artery sling is treated separately (see chapter “Slings and rings”). The origin of one or both pulmonary arteries from the transverse aortic arch via a ductus arteriosus or collateral arteries, or from the descending thoracic aorta via collateral arteries, is treated separately (see chapter “Pulmonary atresia with ventricular septal defect”).
