Bypass surgery is a surgical procedure which is executed for the purpose of relieving angina and decrease the risk of death caused due to coronary artery disease. In this process the arteries or veins from elsewhere part of the body of the patient are grafted to the coronary arteries in order to bypass the atherosclerotic narrowings.

This procedure of surgery helps in the improvement of the blood supply and enhances the coronary circulation which helps in supplying the nutrients to the myocardium or heart muscle. This surgery is generally accomplished with to prevent the possibility of heart stopped. It necessitates in the usage of cardiopulmonary bypass. With the scientific exploration the doctors have now invented several techniques for the purpose of performing the bypass surgery on a living heart.
There are various terminology which are applied in the case of bypass surgery. In all these cases there are one or more of artery or bypass or graft is left out. The most frequently used descriptor for this type of surgery is CABG which is commonly pronounced as cabbage among the doctors. In the recent times a more popular term has come into use which is known as the aortocoronary bypass or ACB has come into popular use. CAGS or Coronary Artery Graft Surgery has been used, mainly used outside the United States and should it not be confused with the process of Coronary Angiography or CAG. There are various terms which are used in the context of bypass surgery whhich are as follows: single bypass, double bypass, triple bypass, quintuple bypass and quadruple bypass. These terms refer to the number of the coronary arteries which are bypassed in the procedure of surgery. In other terminology, a double bypass implies that two coronary arteries will be bypassed that is the left anterior descending or LAD coronary artery and right coronary artery or RCA. The a triple bypass surgery implies that three blood carrying vessels will be bypassed for instance the LAD, RCA, left circumflex artery or LCX.
A greater number of bypasses surgery is done on a person does not signify that a person is sicker nor does a lesser number of person implies that a person is healthier. While a person has undergone a large amount of coronary artery disease or CAD he may receive less bypass grafts. The main reason is the lack of suitable target vessels. A coronary artery may be unsuitable for bypass grafting it if it is small depending on the preference of the surgeon and heavily calcified which implies that the artery does not have a section free of CAD or intramyocardial which signifies that the coronary artery is located within the heart muscle instaed of on the surface of the heart. In the same way if a person is having a single stenosis of the main left coronary then it requires only two bypasses.
