Coronary artery bypass graft surgery is done to go around a
portion of an artery that has been narrowed or blocked by plaque buildup
(atherosclerosis). It is a treatment for coronary artery disease.
The blocked portion of the artery is bypassed using a blood vessel
taken from elsewhere in the body (usually the chest or leg). Blood is
redirected through the new blood vessel, restoring blood flow to the affected
portion of the heart muscle.
