Coronary artery bypass graft, also known as CABG, is a surgical procedure that involves bypassing a blocked artery in the heart. There are several other terms that can be used to refer to this procedure, including coronary bypass, heart bypass, and bypass surgery. Additionally, doctors may use more technical terms to describe specific aspects of the procedure, such as arterial bypass grafting or saphenous vein grafting. Regardless of the terminology used, the goal of coronary artery bypass grafting is to restore healthy blood flow to the heart and reduce the risk of complications from heart disease.
