Heart Bypass Surgery

Heart bypass surgery is a procedure to improve blood flow to the heart muscle. When arteries supplying blood become blocked or narrowed due to plaque buildup, the heart receives less oxygen-rich blood, which can cause chest pain or a heart attack. During surgery, a surgeon takes a healthy blood vessel from another part of your body—often the leg or chest—and creates a new pathway, or "bypass," around the blocked artery. This reroutes blood flow, restoring oxygen and nutrients to the heart muscle. The procedure helps relieve symptoms and reduce the risk of future heart problems.
