Figure 2

Angiographic images from Case  2: (A) lateral projection showing characteristic loop of ARSA; (B) left anterior oblique view of right coronary artery showing a 90% proximal lesion; (C) with subsequent stenting; (D) right anterior oblique caudal view of left coronaries with a 70% circumflex, 90% OM1, and 70% OM3; (E) final result; (F) A 3D volume rendered imaged from a contrast-enhanced CT angiographic dataset demonstrating vessels arising from the arch in the following order: RCCA, LCCA, LSA, and ARSA. ARSA, aberrant right subclavian artery; OM, obtuse marginal; RCCA, right common carotid artery; LCCA, left common carotid; LSA, left subclavian artery; Asc Ao, ascending aorta; Desc Ao, descending aorta.
