what precautions to prevent blockage in heart arteries
A stent is a mesh tube made of metal or sometimes fabric. It is often placed during an angioplasty procedure. An angioplasty is a deflated balloon that your surgeon will thread through your artery to the weakened or blocked area. It is then inflated to open the artery for placement of the stent. The stent safeguards the site to prevent future blockages.
