|---|---|
| coronary arteritis | Inflammation of any or all of the layers of coronary artery walls. (05 Mar 2000) |
| coronary artery | <anatomy, artery> See: right coronary artery, left coronary artery. Synonym: left gastric artery. (05 Mar 2000) |
| coronary artery aneurysm | This refers to a dilation and weakness in the wall of a coronary artery. May occur as a consequence of Kawasaki disease. (27 Sep 1997) |
| coronary artery anomalies | <radiology> Associated with, tetralogy of Fallot (TOF), transposition of great vessels (TGV) (12 Dec 1998) |
| coronary artery branches | <radiology> Right coronary artery, left coronary artery (12 Dec 1998) |
| coronary artery bypass | Surgical therapy of ischemic coronary artery disease achieved by grafting a section of saphenous vein, internal mammary artery, or other substitute between the aorta and the obstructed coronary artery distal to the obstructive lesion. (12 Dec 1998) |
| coronary artery bypass graft | A surgical procedure, known as a coronary artery bypass graft, which involves replacing diseased (narrowed) coronary arteries with veins obtained from the patients lower extremities (autologous graft). During this procedure the patient is placed on a heart bypass machine (heart-lung machine) to allow the surgeon adequate time to perform surgery on the resting (nonbeating) heart. This procedure has proven to extend the lives of individuals with coronary artery disease and improve the quality of life. Recovery in the hospital is approximately 7-10 days. (27 Sep 1997) |
| coronary artery calcification | <radiology> In setting of chest pain, upto 94% will have significant coronary artery calcification (12 Dec 1998) |
| coronary artery disease | The process by which the coronary arteries become narrowed or completely occluded, is known as atherosclerosis. Ultimately, this is the underlying cause of a heart attack. (27 Sep 1997) |
| coronary artery dominance | <radiology> Dominance = source of posterior descending artery (patent ductus arteriosus), 70% right (right coronary artery), 20% balanced, 10% left (left CIRCUMFLEX artery) (12 Dec 1998) |
| coronary artery spasm | A sudden vasoconstriction of a coronary artery depriving the myocardium of blood flow and oxygen. This may clinically manifest as chest pain referred to as variant angina or Printzmetal's angina. May be precipitated by emotional stress, medications, street drugs (cocaine) or on exposure to cold. Treatment includes nitroglycerin or beta-blocker medications. (27 Sep 1997) |
| coronary atherectomy | Instrumental removal, via catheter, of atheromas in coronary arteries. (05 Mar 2000) |
| coronary band | A region of the pododerm; a prominent ridge of corium and underlying tela subcutanea at the top of the hoof from which most of the wall of the hoof grows. Synonym: corium coronae. (05 Mar 2000) |
| coronary bypass | Vein grafts or other conduits shunting blood from the aorta to branches of the coronary arteries, to increase the flow beyond the local obstruction. Synonym: aortocoronary bypass. (05 Mar 2000) |
