Bypass surgery is a procedure that is performed to improve the blood flow to the heart. In this surgery, a new blood vessel is taken from another part of the body and grafted onto the heart to create a bypass around a blocked or narrowed artery. There are several synonyms that are commonly used for bypass surgery, including coronary artery bypass grafting (CABG), heart bypass surgery, and artery bypass surgery. Other related terms that are often used in conjunction with bypass surgery include angioplasty, stenting, and open-heart surgery. While bypass surgery is a serious procedure, it is also one of the most effective methods for resolving heart problems and restoring proper blood flow to the heart.
