| PICSO | pressure-controlled intermittent coronary sinus occlusion |
|---|---|
| RCS | rabbit aorta-contracting substance; red cell suspension; reticulum cell sarcoma; right coronary sinu... |
| Ao | orifice area |
| AVO | aortic valve opening; aortic valve orifice; atrioventricular opening |
| CAVO | common atrioventricular orifice |
| 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) |
| coronary bypass surgery | 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 care unit | A group of beds within a hospital set aside for the care of patients having or suspected of having myocardial infarction. (05 Mar 2000) |
| coronary care units | The hospital unit in which patients with acute cardiac disorders receive intensive care. (12 Dec 1998) |
| coronary cataract | Peripheral cortical developmental cataract occurring just after puberty; transmitted as a hereditary dominant characteristic. (05 Mar 2000) |
| coronary circulation | The circulation of blood through the coronary vessels of the heart. (12 Dec 1998) |
| coronary disease | Damage to the heart. Not enough blood flows through the vessels because they are blocked with fat or have become thick and hard, this harms the muscles of the heart. People with diabetes are at a higher risk of coronary disease. (09 Oct 1997) |
| coronary endarterectomy | Excision of occluding material, including intima and most of the media, from the coronary artery. (05 Mar 2000) |
| coronary failure | Acute coronary insufficiency. (05 Mar 2000) |
| coronary groove | 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) |
