  This article describes coronary artery bypass grafting by Avlliath Jay akrishnan et al. one of the most common reason for coronary artery bypass grafting is narrowing coronary arteries because of atherosclerosis. Atherosclerosis causes chest pain (angina pectoris), myocardial infarction and sudden death. The aim of coronary artery bypass grafting is to release pain, prevention of myocardial infarction and increasing the length of life. In recent years various methods for improvement of cardiac blood supply have been experimented. In 1960s coronary artery bypass grafting developed by using direct sophenous vein by effort of Favalero, Effler et al in the United State. In this method sophenous veins were applied as graft instead of obstructed coronary artery. First in the Soviet :::union:::, Kolesor connected intramammary artery to coronary artery. Then Green et al used this method in the United State.
