Definition
Coronary artery bypass graft (CABG) is a surgical procedure for coronary artery disease in which arteries or veins from other parts of the body are grafted from the aorta to the coronary arteries in order to bypass the blocked portions. Indications for surgery include disease of the left main coronary artery and/or disease of all three coronary arteries and abnormal ventricular function. It may be performed in patients with severe angina which is unresponsive to medical management.
Patients undergo general anesthesia, and a midline incision (median sternotomy) allows the surgeon to visualize the heart and vessels. The artery or vein grafts are then harvested. Frequently used vessels include the internal thoracic arteries, radial arteries, and saphenous veins. The heart is then stopped using a special mixture of chemicals, and the patient is placed on cardiopulmonary bypass where the blood flow returning to the heart is diverted through a heart–lung machine that...
