Coronary Artery Bypass

Coronary artery bypass is a surgical procedure to create a new blood circulation route to reach the myocardium (heart muscle). It is performed when a branch of the coronary artery got narrowed or blocked, as in the case of angina pectoris. In a coronary artery bypass surgery, a piece of a vein from the leg or artery from the chest is grafted to a coronary artery branch to bypass the narrowed section of the blood vessel to keep that sector of the myocardium supplied with oxygenated blood and avoid a necrosis of the muscular cells.
