Anomalous Coronary Artery
Anomalous Coronary Artery The normal anatomy for the coronary arteries involves their origin from the aorta at each of two separate sites. Sometimes people can be born with the origin of a coronary artery that comes from an abnormal site and this can lead to problems of coronary ischemia which can subsequently lead to heart attack. Not all coronary anomalies need surgery, but some do and the specific operation depends on which of the many varieties of coronary anomalies is present.
RELATED TERMS--------------------------------------
Anatomy
The study of form. Gross anatomy involves structures that can be seen with the naked eye. It is as opposed to microscopic anatomy (or histology) which involves structures seen under the microscope.
Arteries
Blood vessels that carry blood away from the heart to the arms, legs, head, body and organs.
Aorta
The largest artery in the body and the primary blood vessel leading from the heart to the body.
Artery
A blood vessel that carries blood from the heart to the body.
Abnormal
Not normal. Deviating from the usual structure, position, condition, or behavior. In referring to a growth, abnormal may mean that it is cancerous or premalignant (likely to become cancer).
Ischemia
Decreased flow of oxygenated blood to an organ due to obstruction in an artery.
Heart
The hollow, muscular organ responsible for pumping blood through the circulatory system.
Anomalies

PREVIOUS AND NEXT TERMS--------------------------------------
Angina (also called angina pectoris)
Discomfort or pressure, usually in the chest, caused by a temporarily inadequate blood supply to the heart muscle. Discomfort may also be felt in the neck, jaw or arms. A common symptom of coronary artery disease, angina usually occurs during periods of physical or emotional stress and is relieved by rest.
Angiotension-Converting Enzyme Inhibitors (ACE inhibitors)
A group of drugs used to treat high blood pressure and heart failure. ACE inhibitors block a specific enzyme (ACE or angiotensin-converting enzyme) which retains salt in the kidney and can cause heart and blood pressure problems.
Angiotensin II Receptor Blockers (ARBs)
A class of medicines used to treat high blood pressure.
Ankle Transmetatarsal and Toe Tracings
A procedure used to test the arterial blood flow to the hands and feet.
Annulus
A ring of tough fibrous tissue which is attached to and supports the leaflets of the heart valve.
Anomalous Coronary Artery
Antiarrhythmic
A drug that is used to treat abnormal heart rhythms.
Anticoagulant ("blood thinner")
A medication that prevents blood from clotting; used for people at risk for stroke or blood clots.
Antihypertensive Drug
A drug that reduces hypertension (high blood pressure).
Antiplatelet Medication
A medication, such as aspirin or plavix, used to prevent platelets from clumping together to cause clots to form. Used for people at risk for stroke or blood clots.
Aortic Arch Replacement
The aortic arch is that segment of the aorta between the ascending and descending portions. The aortic arch provides the origin for the blood vessels to the upper part of the body, specifically the arms and head. Surgical diseases of the aortic arch can require a replacement of this large blood vessel with preservation of the vessels to the upper body. The most common diseases requiring replacement are an aneurysm of the aortic arch or an aortic dissection involving the aortic arch.
