The heart has three major arterial systems which provide oxygenated blood to the muscle so that it can function properly. Atherosclerosis (the buildup of cholesterol and other materials in blood vessels) causes injury and in severe cases, blocks the flow of blood. In the figure to the right, you will notice normal blood flowing easily through an artery (top figure). As cholesterol and other cellular debris begins to accumulate within the artery, blood flow diminishes, and heart muscle begins to starve and eventually die.

Treatment for this disease can be medical, angioplasty, or surgery. The determining factor for treatment is usually the severity as well as the risk of the treatment. In most circumstances bypass surgery provides the best long-term results.

Bypass surgery is performed by placing arteries or veins around the areas of blockage. The arteries from the chest wall called internal mammary or thoracic arteries are most commonly used. Other arteries such as the radial artery from the arm can also be used. The advantages and reasons for using arteries for bypass are their inherent properties in resisting development of atherosclerosis which allow these bypasses to remain open and flowing for many years. The arteries or veins are actually sewn to the heart to "bypass" the area where there is a cholesterol blockage.
