Coronary Bypass Surgery

When angioplasty is not advisable for treating a patient's advanced coronary artery disease, coronary artery bypass may be done. This surgical procedure creates a new route for blood flow around the stenosis using either a piece of vein (graft) from the patient's leg or an artery from the chest (graft) to effectively "bypass" the narrowed coronary artery segment.
