Coronary Artery Bypass Surgery
What Is It?
Coronary artery bypass surgery is a procedure that detours (or bypasses) blood around a blocked section of one or more coronary arteries. It is also called coronary artery bypass grafting or CABG (pronounced "cabbage").
Coronary arteries are the blood vessels that supply the heart with oxygen and nutrients. You have several coronary arteries. They are named for their location. For example, your doctor may speak of the left main coronary artery, left anterior descending artery or the right coronary artery.
