Coronary Artery Bypass

Coronary artery bypass surgery is performed when a coronary artery becomes blocked or partially blocked by a thickening of the walls of the artery or a narrowing of the artery caused by plaque deposits. These blocked arteries can obstruct blood flow, depriving the body of oxygen and nutrient-rich blood, can cause chest pain, and, if left untreated, can lead to a heart attack.

During coronary artery bypass surgery, arteries or veins from other parts of the body (typically the leg) are removed and surgically reattached to reroute the blood around the blocked artery, restoring normal blood flow and improving the supply of blood and oxygen to the heart.
