| 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) |
| 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) |
