| subclavian steal | Obstruction of the subclavian artery proximal to the origin of the vertebral artery; blood flow through the vertebral artery is reversed and the subclavian artery thus "steals" cerebral blood, causing symptoms of vertebrobasilar insufficiency (subclavian steal syndrome); manifest during vigorous use of an upper extremity. (05 Mar 2000) |
| subclavian steal syndrome | <syndrome> Aortic arch syndrome, also referred to by many as vertebral-basilar artery disease, carotid artery occlusive syndrome and subclavian steal syndrome is characterised by a constellation of signs and symptoms which occur secondary to abnormalities in the major arteries which extend off of the aortic arch. These abnormalities are structural and most often secondary to the effects of atherosclerosis, blood clots, trauma or a congenital abnormality. Symptoms of this condition include various neurologic symptoms, reduction in pulse and changes in blood pressure. (27 Sep 1997) |

| right coronary artery branches | <radiology> Conus branch, branch to S-A node, acute marginal branches, branches to posterior left ventricle, branch to A-V node, posterior descending artery (patent ductus arteriosus, 90%), hence, right coronary a. Is usually dominant (12 Dec 1998) |
| circumflex branch of left coronary artery | <anatomy, artery> Terminal branch (with anterior interventricular artery) of left coronary artery which runs to left and then posteriorly in the coronary groove supplying atrial and ventricular branches.
