Coronary Artery Bypass Grafting (CABG)
In coronary artery bypass grafting (CABG), doctors take an artery or vein from another part of the body to connect the aorta (the major artery that takes blood from the heart to the rest of the body) to a coronary artery past the point of its blockage. Blood flow is thus rerouted, skipping over (bypassing) the narrowed or blocked area.
