Peer Review Status: Internally Peer Reviewed

The origins of this artery may vary as follows: a) It may arise from the subclavian, behind or in front of scalenus anterior; b) the right artery may arise from the ascending aorta; or c) it may arise in common with the inferior thyroid.

The left internal thoracic artery has been shown by Robicsek, et al.(1967), to give rise to a anterior interventricular (descending) coronary artery, the usual supply being the left anterior descending coronary artery (LAD-CA).
