: In a [[Coronary Bypass]] an [[artery]] from another part of the body is cut out and attached to the [[Coronary Artery]] to provide a path for [[blood]] to flow around the blockage.

: A [[Stent]] is a tube which can be placed inside the narrow [[artery]] and then expanded to widen the [[artery]]. The [[Stent]] is left inside the [[artery]] to hold it open.
