Physicians perform a stenting procedure to reopen arteries that are closed or narrowed by a buildup of plaque. A stent is a small wire mesh tube used to prop open a clogged or closed artery.
During an angioplasty procedure in the catheterization lab, the cardiologist places the stent over an angioplasty balloon catheter and moves it into the area of the blockage. The balloon is inflated, the stent expands, and the stainless steel or titanium spring-like structure forms a rigid support to hold open the weak artery wall. Learn More about Angioplasty
Today, many stents are coated with medication to prevent scar tissue from forming and blocking the artery again. These drug-eluting stents are quickly becoming the standard of care.
The stent remains in the artery permanently, holding it open to improve blood flow to the heart muscle. It also helps to relieve symptoms such as chest pain.
A procedure called an angiogram is perfomed prior to angioplasty. Learn More about Angiograms
