A Heart Bypass Surgery aims at replacing the damaged arteries inside the heart. In this surgery, a surgeon uses blood vessels from another part of the body to repair the damaged arteries. This operation is also termed as coronary artery bypass surgery.
This operation is performed when the arteries get damaged/blocked. Oxygenated blood is supplied to the heart's muscles via the coronary arteries. If they get blocked, the heart cannot function properly and may lead to heart failure.
