Coronary artery bypass graft (CABG) is also called coronary artery bypass surgery. It is an operating procedure that treats coronary artery disease (CAD). CAD is the narrowing and blockage of coronary arteries (the arteries that supply blood to the heart muscles) due to buildup of deposits of cholesterol and other substances in the coronary artery. Coronary artery bypass surgery is done by taking blood vessels from another part of the body, commonly from the arms, legs, chest, or wrist, to make a new pathway for the flow of blood and oxygen into the heart, known as bypass. The new and healthy blood vessel is called a graft. 

 

Coronary artery bypass graft is an example of  total artery revascularization. The aim of revascularization is to restore blood flow and blood supply to the heart from the damaged arteries. In the total artery revascularization technique, the healthy left internal mammary arteries (LIMA) and the right internal mammary arteries (RIMA), from the left and right sides of the chest are used respectively. The chest grafts are preferred for use in bypass surgeries as they are long-lasting, and have capability to repair. Moreover, they can change according to the body’s demand and are resistant to cholesterol (plaque) blockages in the arteries.

FAQ's About CABG

zWhat happens after a CABG procedure?

After a bypass graft procedure, you may need to reside in the hospital for seven to ten days depending on your health condition. So that doctors can closely monitor your recovery and check for any complications. During this period, you may be on drips and tubes that drain body fluids, blood, and urine from the body, along with providing you with the needed fluids and medications.
