Coronary Artery Bypass Grafting
Coronary Artery Bypass Grafting (pronounced as kuh-ROH-nuh-ree AR-tuh-ree BY-pass GRAF-ting), often abbreviated as CABG (pronounced as CABG), is a type of surgery that improves blood flow to the heart. It's used for individuals who have severe coronary heart disease (CHD).
Etymology
The term "Coronary Artery Bypass Grafting" is derived from the procedure's purpose and method. "Coronary" refers to the heart's coronary arteries, "Bypass" signifies the method of rerouting blood around the blocked arteries, and "Grafting" refers to the use of blood vessels taken from another part of the body to create the bypass.
Procedure
In CABG, a healthy artery or vein from the body is connected, or grafted, to the blocked coronary artery. The grafted artery or vein bypasses (that is, goes around) the blocked portion of the coronary artery. This creates a new path for oxygen-rich blood to flow to the heart muscle.
Related Terms
- Angina: Chest pain or discomfort that occurs when the heart muscle doesn't get enough oxygen-rich blood.
- Atherosclerosis: A disease in which plaque builds up inside the arteries.
- Myocardial Infarction: Commonly known as a heart attack, occurs when blood flow decreases or stops to a part of the heart, causing damage to the heart muscle.
