| Angioplasty uses a balloon device to compress the plaque against the artery wall. This procedure is also known as PTCA (percutaneous transluminal coronary angioplasty). In more than 70% of procedures performed at Hoag Heart and Vascular Institute, another device is also used in conjunction with the balloon. These are tiny metal structures called stents.
Stents are mounted on an angioplasty balloon and positioned at the site of the blockage. When the balloon is inflated, the stent expands and is pressed into the inner wall of the artery. The balloon is deflated and removed with the stent remaining in place, serving as permanent scaffolding for the newly widened artery. |
