Coronary Artery Bypass Graft Surgery CABG recommended for patients with obstructive CAD whose survival will benefit compared to medical therapy or PCI. In addition, other How CABG is Performed

patients with angina refractory to medical therapy may receive a recommendation for CABG if PCI cannot be performed. The procedure

involves the construction of one or more grafts between the arterial and coronary circulations.

CABG surgery circumvents an occluded coronary artery by using a segment of the saphenous vein, radial artery, or internal mammary artery to restore blood flow to the heart.
