Treatment of Coronary Heart Disease
- 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.
