CABG is a surgical procedure in which one or more blocked coronary arteries are bypassed by a blood vessel graft to restore normal blood flow to the heart. These grafts usually come from the patient’s own arteries and veins located in the chest (thoracic), leg (saphenous) or arm (radial). The graft goes around the blocked artery (or arteries) to create new pathways for oxygen-rich blood to flow to the heart.

The goals of the procedure are to relieve symptoms of coronary artery disease (including angina), enable the patient to resume a normal lifestyle and to lower the risk of a heart attack or other heart problems.

At Cleveland Clinic, bypass surgery may be performed in combination with other heart surgeries, when necessary, such as valve surgery, aortic aneurysm surgery or surgery to treat atrial fibrillation (an irregular heart beat).

Who is eligible to receive coronary artery bypass graft surgery?

Diagnostic tests have helped your heart doctor identify the location, type and extent of your coronary artery disease. The results of these tests, the structure of your heart, your age, the severity of your symptoms, the presence of other medical conditions, and your lifestyle will help your cardiologist, surgeon and you determine what type of treatment is best.
