Aortocoronary bypass is a surgical procedure that involves creating a new pathway for blood to flow to the heart muscle. There are a variety of synonyms for this procedure, including coronary artery bypass grafting, CABG, heart bypass surgery, and simply bypass surgery. Additionally, depending on the specific arteries and vessels involved, the procedure may be referred to as a left internal mammary artery bypass, a radial artery bypass, or a saphenous vein bypass. Regardless of the specific terminology used, aortocoronary bypass is a critical and potentially lifesaving procedure for individuals suffering from coronary artery disease or other conditions that prevent adequate blood flow to the heart.
