Coronary artery bypass grafting is a coronary revascularization by surgery. Dr Rene Favaloro performed his first coronary bypass operation in May 1967 with an interposed saphenous vein graft (SVG) and shortly thereafter used aortocoronary bypasses sutured proximally to the ascending aorta. In the words of Dr Denton Cooley, "Although he [Favaloro] was always hesitant to carry the moniker of 'father' of coronary artery bypass surgery, he is the surgeon we should credit with introducing coronary bypass surgery into the clinical arena" [9]. It has been shown to be highly effective in the relief of severe angina and under some circumstances has the capability for considerably prolonging useful life. The stenosed segment of the coronary artery is bypassed using an arterial or venous conduit, and by this it reestablishes the blood flow to the distal ischemic myocardial area. Many studies have shown that surgical revascularization is superior to medical and percutaneous interventional management for multivessel CAD. Full workup should be done

**4.1 The anatomical factors which favor the CABG are as follows**

2. Significant proximal left anterior descending (LAD) disease.

5.Depressed left ventricular (LV) ejection fraction.

Indications for CABG can be classified as per **Table 1**.

2. Significant stenosis (>75%) of proximal LAD with double- or triple-vessel
