Coronary Artery Bypass Graft

Also known as bypass surgery or bypass grafting, coronary artery bypass graft (CABG), is one of the most common and most effective of all the cardiovascular surgeries. During this procedure, the chest is opened, the heart is stopped, and blood is pumped through a heart-lung machine, which keeps it oxygenated. The surgeon removes an artery or vein from another part of the body (often the leg) and places it in the heart, forming a new vessel though which blood can flow and supply the food and oxygen needs of the cells of the heart muscle. The new vessel “bypasses” a clogged or blocked vessel. A patient may undergo a single, double, triple, even a quadruple bypass depending on how many coronary arteries are blocked.
