Coronary Artery By-pass

A few patients with angina or those who have had a heart attack may need coronary artery by-pass (heart by-pass) surgery. The medical name for this procedure is called coronary artery by-pass grafting (CABG).  A piece of vein from your leg (or artery from inside your chest) is used.  It is stitched (grafted) onto your coronary artery before the narrowed bit.  It takes the blood past the blockage and back into the artery after the blockage.  So it "by-passes" the narrowed bit.  This operation requires a general anesthetic.
