If the heart is no longer functioning properly due to atherosclerosis or another form of heart disease, bypass surgery may be recommended. With this procedure, a blood vessel from somewhere else in the body is removed and a graft created to bypass a vessel in the heart that has become damaged and blocked.
This procedure is carried out in two different ways: a traditional bypass surgery and an off-pump bypass surgery, also called an off-pump CABG (coronary artery bypass graft). With this latter procedure, the heart-lung machine is not used.
