Open bypass surgery is a procedure that is performed to open the arteries that are blocked with build up of plaque. This procedure helps create a separate route for the blood to flow without any disturbance. Plaque is usually the build up of calcium, cholesterol and other substances.

When the plaque builds up on the walls of the artery the passage for the blood is narrowed. When the blood flow to the heart is reduced you experience severe heart attack or angina.

Who might need to undergo open heart bypass surgery?

People with severe coronary heart diseases that may result in a heart attack are treated with heart surgery for blockage. People who have had a heart attack and have heart damage yet still have clogged arteries may be treated by a coronary bypass surgery.

If other treatments, including medication or lifestyle changes, have failed, your doctor may advise a bypass surgery. If you have severe blockages in the heart arteries that supply most of the portion of the heart muscle with blood, your doctor may advise coronary bypass surgery, especially if your heart’s ability to pump blood has already been deeply affected.
