"Anomalous origin of one pulmonary artery from the aorta (AOPA) represents a rare congenital cardiovascular anomaly. One pulmonary artery originates from the aorta, and the other from the right ventricular outflow tract 1-3. It more often involves the right pulmonary artery than the left pulmonary artery and is characterised by separate aortic and pulmonary valves 1-4."
"An anomalous origin of one pulmonary artery from the aorta (AOPA) is also known under the term ‘hemitruncus’, although this description is probably inaccurate 1,4."
"Chest radiographs might display increased pulmonary vascular markings in the lung affected by the AOPA 3,6."
