coronary bypass surgery

n.
A surgical procedure performed to improve blood supply to the heart by creating new routes for blood flow when one or more of the coronary arteries become obstructed. The surgery involves removing a healthy blood vessel from another part of the body, such as the leg, and grafting it onto the heart to circumvent the blocked artery.
