| coronary | <anatomy, cardiology> A term applied to vessels, nerves, ligaments, etc. The term usually denotes the arteries that supply the heart muscle and, by extension, a pathologic involvement of them. Origin: L. Corona, Gr. Koron = encircling in the manner of a crown (18 Nov 1997) |
|---|---|
| coronary aneurysm | Aneurysm of a coronary vessel. A coronary artery aneurysm is rarely congenital; it is usually due to atherosclerosis, inflammatory processes, or a coronary fistula. (12 Dec 1998) |
| coronary angiography | Radiography of the vascular system of the heart muscle after injection of a contrast medium. (12 Dec 1998) |
| coronary angioplasty | <cardiology, procedure> Percutaneous coronary angioplasty. This procedure involves the introduction of a thin flexible, hollow catheter into a artery in the groin. The catheter is advanced through the blood vessel to the heart. A special balloon tip on the catheter allows the physician to open a diseased (occluded) coronary artery by inflating the balloon and dilating the diseased vessel. (27 Sep 1997) |
| coronary arteries | The arteries that supply the heart with oxygenated blood. There are a number of vessels that are important with regard to coronary artery disease, but the right coronary artery, posterior descending, left main coronary artery, left anterior descending and left circumflex are probably the most frequently surgically grafted coronary vessels. (27 Sep 1997) |
| coronary arteriosclerosis | Atherosclerosis of the coronary arteries. (12 Dec 1998) |
| 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) |
| anterior coronary plexus | The part of the cardiac plexus that accompanies the coronary arteries on the anterior aspect of the heart. (05 Mar 2000) |
|---|---|
| atherectomy, coronary | Percutaneous transluminal procedure for removing atheromatous plaque from the coronary arteries. Both directional (for removing focal atheromas) and rotational (for removing concentric atheromatous plaque) atherectomy devices have been used. (12 Dec 1998) |
| valve of coronary sinus | A delicate fold of endocardium at the opening of the coronary sinus into the right atrium. Synonym: valvula sinus coronarii, coronary valve, thebesian valve. (05 Mar 2000) |
| percutaneous transluminal coronary angioplasty | Percutaneous transluminal angioplasty of coronary artery or arteries. (05 Mar 2000) |
| right coronary artery | <anatomy, artery> Origin, right aortic sinus; distribution, it passes around the right side of the heart in the coronary sulcus, giving branches to the right atrium and ventricle, including the atrioventricular branches and the posterior interventricular branch. Synonym: arteria coronaria dextra. (05 Mar 2000) |
| 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. Synonym: ramus circumflexus arteriae coronariae sinistrae. (05 Mar 2000) |
| posterior coronary plexus | The portion of the cardiac plexus that accompanies branches of the coronary arteries on the posteroinferior surface of the heart. (05 Mar 2000) |
| internal mammary-coronary artery anastomosis | Direct myocardial revascularization in which the internal mammary artery is anastomosed to the right coronary artery, circumflex artery, or anterior descending coronary artery. The internal mammary artery is the most frequent choice, especially for a single graft, for coronary artery bypass surgery. (12 Dec 1998) |
| transluminal percutaneous coronary angioplasty | <cardiology, procedure> Dilatation of an occluded coronary artery (or arteries) by means of a balloon catheter to restore myocardial blood supply. (07 Mar 2000) |
| unroofed coronary sinus syndrome | <syndrome> A spectrum of cardiac anomalies in which part or all of the common wall between the coronary sinus and the left atrium is absent. (05 Mar 2000) |
| left coronary artery | <anatomy, artery> Origin, left aortic sinus; distribution, it divides into two major branches, an anterior interventricular which descends in the anterior interventricular sulcus, and a circumflex branch which passes to the diaphragmatic surface of the left ventricle; gives atrial, ventricular, and atrioventricular branches. Synonym: arteria coronaria sinistra. (05 Mar 2000) |
| left coronary artery branches | <radiology> Left anterior descending (LAD) artery, diagonal branches, septal branches (short br. at 90' angle), left circumflex artery (LCA), obtuse marginal branches (12 Dec 1998) |
| left coronary vein | <anatomy, vein> Begins at the apex of the heart (where it anastomoses with the middle cardiac vein), runs first with the anterior interventricular artery as it ascends the anterior interventricular groove, then turns to the left as it approaches or reaches the coronary groove to run with the circumflex branch of the left coronary artery; it merges with the oblique vein of the left atrium to form the coronary sinus. Synonym: vena cordis magna, left coronary vein, vena cardiaca magna. (05 Mar 2000) |
