Coronary artery bypass surgery, also known as coronary artery bypass graft (CABG, pronounced "cabbage") is a surgical procedure for coronary artery disease (CAD) aiming to relieve angina, stall progression of ischemic heart disease and increase life expectancy. The goal is to bypass the stenotic lesions in native heart arteries using arterial or venous conduits, thus restoring adequate blood supply to the previously ischemic heart.
