Angiography of a patient who had redo coronary artery bypass grafting in 1987. He had three grafts and has a recurrence of angina.

The Aortogram in LAO shows?

A) 1 = right subclavian artery, 2 = common carotid artery, 3 = left subclavian artery
B) 1 = brachiocephalic artery, 2 = right subclavian artery, 3 = left subclavian artery
C) 1 = right carotid artery, 2 = brachiocephalic artery, 3 = left subclavian artery
D) 1 = right subclavian artery, 2 = left subclavian artery, 3 = brachiocephalic artery
E) 1 = brachiocephalic artery, 2 = left carotid artery, 3 = left subclavian artery

Correct Answer is E

Comment:

The aortogram tests basic aortic arch, head, and neck anatomy. The first branch from the right (1) is the brachiocephalic (‘innominate’) artery which gives off the right subclavian artery (origin of the RIMA) and right common carotid artery. The middle branch (2) is the left common carotid artery. The third branch (3) is the left subclavian artery which give off the LIMA.
