Coronary artery bypass grafting (CABG) is one of the most commonly performed open heart surgeries. In this procedure, a vein from the leg - or an artery from the chest wall or arm - is used to bypass a coronary artery that is narrowed or blocked by fatty plaque buildup.

Because a surgeon can perform several bypasses during a single surgery, CABG is often a good option for people with narrowing or blockage in several coronary arteries. CABG is also a good option for people with severe angina or severe narrowing in the left main coronary artery.

Because it restores the flow of oxygenated blood to the heart, CABG can give a person a whole new lease on life. However, keep in mind that the new grafts are just as vulnerable to fatty plaque buildup as your original arteries were. This means a careful treatment plan to ensure that the grafts stay as healthy and plaque-free as possible.
