| coronary insufficiency | Inadequate coronary circulation leading to anginal pain. Synonym: coronarism. (05 Mar 2000) |
|---|---|
| coronary ligament of knee | Portions of the articular capsule of the knee joint which connect the circumference of the menisci with the margins of the condyles of the tibia. (05 Mar 2000) |
| coronary ligament of liver | Peritoneal reflections from the liver to the diaphragm at the margins of the bare area of the liver. Synonym: ligamentum coronarium hepatis. (05 Mar 2000) |
| coronary nodal rhythm | Formerly applied by some authorities to the electrocardiographic pattern of normal upright P waves in leads I and II with a short P-R interval. (05 Mar 2000) |
| coronary node | The uppermost part of the atrioventricular node. (05 Mar 2000) |
| coronary occlusion | Blockage of a coronary vessel, usually by thrombosis or atheroma, often leading to myocardial infarction. (05 Mar 2000) |
| coronary ostial stenosis | Narrowing of the mouths of the coronary arteries as a result of syphilitic aortitis or atherosclerosis. (05 Mar 2000) |
| coronary perfusion pressure | The pressure at which blood proceeds through the coronary circulation, mainly in diastole. (05 Mar 2000) |
| coronary plexus | The continuation of the cardiac plexus onto the coronary arteries. Synonym: plexus coronarius cordis. (05 Mar 2000) |
| coronary-prone behaviour | The behaviour that characterises type A personality pattern. (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 tendon | One of four fibrous rings that surround atrioventricular and arterial orifices of the heart, providing attachment for the valve leaflets and maintaining patency of the orifice. As part of the fibrous skeleton of the heart, the fibrous rings also provide origin and insertion for the myocardium. Synonym: annulus fibrosus cordis, annulus fibrosus, coronary tendon, fibrous ring, Lower's ring. (05 Mar 2000) |
| coronary thrombosis | A blood clot in the lumen of a coronary artery. This is the mechanism by which a myocardial infarction results. A thrombus forms when microscopic cracks (from the effects of atherosclerosis) occur in the coronary vessel wall. These tiny cracks expose collagen, thus triggering platelets to adhere to the site and a blood clot to form. (27 Sep 1997) |
| 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) |
