Coronary bypass surgery involves taking a piece of vein or artery from somewhere else in your body that does not have a blockage, and then using that piece of vein or artery to reroute the blood and to bypass the blockage of the vessels in your heart.  The best results are usually obtained with arterial conduit:

• The internal mammary artery (from behind your breast bone) offers a 95% chance of remaining open for ten years.
• The radial artery (from your arm) offers more than an 80% chance of remaining open for ten years.
• A vein from your leg offers only a 50% chance of remaining open for ten years.

Coronary bypass surgery is specifically designed to deliver more blood supply to the muscles of your heart.  It can eliminate the symptoms of angina, increase your chances of survival, and improve the quality of your life.
