(A) Right aortic arch with mirror image branching pattern. The left innominate artery (IA) courses leftwards and bifurcates into the left subclavian artery (LSCA) and left common carotid artery (LCCA). (B) The left descending thoracic aorta (Desc Ao) lies posterior to the left lower pulmonary vein (LLPV) on the left side of the vertebral body (VB). (C) The left patent ductus arteriosus (PDA) completes the vascular ring.

RLPV: right lower pulmonary vein; LPA: left pulmonary artery.
