In coronary artery bypass, what is used to bypass the obstruction?

Coronary artery bypass grafting creates a new route for blood to reach heart muscle beyond a blocked artery. A healthy segment of artery or vein is taken from another part of the body and attached to the coronary artery beyond the obstruction, forming a detour around the blocked portion. This is different from balloon angioplasty, where a balloon is inflated inside the artery to push plaque against the vessel wall to widen the lumen without adding a new path. Atherectomy uses a catheter to remove plaque, and placing a stent keeps a dilated segment open after such a procedure; neither adds a graft to bypass the blockage.
