|---|---|
| coronary sinus | A short trunk receiving most of the cardiac veins, beginning at the junction of the great cardiac vein and the oblique vein of the left atrium, running in the posterior part of the coronary sulcus and emptying into the right atrium between the inferior vena cava and the atrioventricular orifice. Synonym: sinus coronarius. (05 Mar 2000) |
| coronary sinus rhythm | An ectopic atrial rhythm supposedly originating from a pacemaker at the mouth of the coronary sinus; recognised in the electrocardiogram by P-waves that are inverted in leads II, III, and a VI with a normal or prolonged P-R interval; an ectopic ("lower") atrial rhythm. (05 Mar 2000) |
| coronary steal | A steal caused by anomalous origin of the coronary artery from the pulmonary artery. (05 Mar 2000) |
| coronary sulcus | A groove on the outer surface of the heart marking the division between the atria and the ventricles. Synonym: sulcus coronarius, atrioventricular groove, atrioventricular sulcus, auriculoventricular groove, coronary sulcus. (05 Mar 2000) |
| coronary valve | 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) |
| coronary vasospasm | Spasm of the large- or medium-sized coronary arteries. (12 Dec 1998) |
| coronary vein | <anatomy, vein> Arises from a union of veins from both surfaces of the cardia of the stomach and an oesophageal tributary from the cardiac portion of the oesophagus; it runs in the lesser omentum and empties into the portal vein. See: oesophageal veins. Synonym: vena gastrica sinistra, coronary vein, vena coronaria ventriculi. (05 Mar 2000) |
| coronary vessel anomalies | Defects of coronary arteries or veins including anomalous origin, arteriovenous fistula or aneurysm, myocardial bridging, or other abnormalities of structure or development. (12 Dec 1998) |
| coronary vessels | The veins and arteries of the heart. (12 Dec 1998) |
| 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) |
