One of the options to treat clogged arteries is a minimally invasive treatment known as angioplasty.
In this procedure, a very small balloon is inserted into the clogged artery and inflated to push the plaque build-up against the wall of the artery. In heart disease patients who have undergone balloon angioplasty, re-blockage can occur. In fact, it occurs in up to 50% of all patients who have undergone an angioplasty. This re-blockage is called restenosis, and may require another procedure to re-open the artery. To help reduce the risk of re-blockage and keep the treated arteries open, stents are used in the vast majority of angioplasties.
Stents are small, mesh metal tubes that prop open the heart's blood vessels.
The stent procedure may involve the use of a drug-coated stent or an uncoated stent. |
