Coronary Bypass Surgery


Image Caption: The procedure is done when a person has one or more blocked coronary arteries, which have prevented the heart itself from getting an adequate blood supply. This is a life-saving surgery that corrects for the blockages and restores blood supply to the heart by rerouting the flow of blood. During the procedure, a synthetic tube or a portion of a blood vessel from elsewhere in the patient's body is sutured into a position on the coronary artery beyond the blockage, with the other end of the graft connected to a portion before the blockage, or on the aorta itself. The blood is now rerouted around the blockage and bloodflow can continue as it should.

Coronary Artery Bypass Surgery

Also called: Bypass surgery, CABG, Coronary artery bypass graft

In coronary artery disease (CAD), the arteries that supply blood and oxygen to your heart muscle grow hardened and narrowed. You may try treatments such as lifestyle changes, medicines, and angioplasty, a procedure to open the arteries. If these treatments don't help, you may need coronary artery bypass surgery.

The surgery creates a new path for blood to flow to the heart. The surgeon takes a healthy piece of vein from the leg or artery from the chest or wrist. Then the surgeon attaches it to the coronary artery, just above and below the narrowed area or blockage. This allows blood to bypass (get around) the blockage. Sometimes people need more than one bypass.

The results of the surgery usually are excellent. Many people remain symptom-free for many years. You may need surgery again if blockages form in the grafted arteries or veins or in arteries that weren't blocked before. Lifestyle changes and medicines may help prevent arteries from becoming clogged again.

Coronary artery bypass surgery, also known as coronary artery bypass graft (CABG, pronounced "cabbage") surgery, and colloquially heart bypass or bypass surgery, is a surgical procedure performed to relieve angina and reduce the risk of death from coronary artery disease. Arteries or veins from elsewhere in the patient's body are grafted to the coronary arteries to bypass atherosclerotic narrowings and improve the blood supply to the myocardium (heart muscle). This surgery is usually performed with the heart stopped, necessitating the usage of cardiopulmonary bypass; techniques are available to perform CABG on a beating heart, so-called "off-pump" surgery.
