Coronary artery bypass grafting

Coronary artery bypass grafting (CABG) is a procedure to improve poor blood flow to the heart. It may be needed when the arteries supplying blood to heart tissue, called coronary arteries, are narrowed or blocked.

Coronary artery bypass grafting can be defined as open heart surgery in which a section of a blood vessel is grafted from the aorta to the coronary artery to bypass the blocked section of the coronary artery and improve the blood supply to the heart.

This surgery uses a graft (blood vessel from another part of your body) to make a new pathway (bypass) around a blockage.

The aim of CABG is to increase the blood supply in coronary arteries by obtaining complete revascularization of all severe stenotic epicardial coronary arteries with a diameter larger than 1 mm. However, optimal patency rates can be obtained in saphenous vein grafts with a distal lumen of ≥ 2 mm. Most patients undergoing CABG have extensive three system disease, often with important stenoses in more than three coronary branches.

Bypass surgery will improve blood flow to patient heart. This reduces patient chances of a heart attack. And once patient had a surgery, he can focus on managing the risk factors for coronary artery disease. This will decrease his chances of developing new blockages.
