The aortic arches develop from the aortic sac, with a pair of branches (right and left) traveling within each pharyngeal arch and ending in the dorsal aorta. DOPA is often incorrectly labeled as absent pulmonary artery or pulmonary artery agenesis (2). The aortic valve opens and closes with each heartbeat, allowing blood to flow from the heart to the aorta. Semilunar valves connect your heart ventricles (lower chambers) and arteries.

The diameter of the descending aorta should not exceed 25mm.[8][9]. The normal left aortic arch results from regression of the right arch between the right subclavian artery and the descending aorta, including the Ductus arteriosus then regresses to become ligamentum arteriosum during later life.
