2. Surgery

Sometimes, cardiac catheterization enables surgery on the arteries of the heart. For example, if one of the arteries of the heart is too narrow, cardiac catheterization can widen the narrowed artery using a special balloon. Afterward, the surgeon can place a stent to keep the artery open and blood flowing freely. Cardiac catheterization may also be used to replace blocked or diseased vessels with healthy tissue.
