A stent is a small mesh tube that’s used to treat narrowed or weakened arteries in the body.

You may have a stent placed in an artery as part of a procedure called angioplasty (AN-jee-oh-plas-tee). Angioplasty can restore blood flow through narrowed or blocked arteries. Stents help prevent arteries from becoming narrowed or blocked again in the months or years after treatment with angioplasty. You may also have a stent placed in a weakened artery to improve blood flow and to help prevent the artery from bursting.

Stents are usually made of metal mesh, but sometimes they’re made of fabric. Fabric stents, also called stent grafts, are used in larger arteries. Some stents are coated with medicines that are slowly and continuously released into the artery. These medicines help prevent the artery from becoming blocked again.

New treatment strategy effective in preventing bleeding in AF patients who underwent PCI, study shows

A new study led by clinician-researchers at Beth Israel Deaconess Medical Center testing the safety and effectiveness of anticoagulant strategies for patients with atrial fibrillation who undergo stenting procedures has shown that therapies combining the anticoagulant drug rivaroxaban with either single or dual anti-platelet therapy were more effective in preventing bleeding complications than the current standard of care.

New guidelines recommend use of antiplatelet therapy and exercise program for treatment of PAD

New guidelines recommend use of antiplatelet therapy and exercise program for treatment of PAD

New guidelines for the treatment of peripheral artery disease (PAD), include recommendations on the use of antiplatelet therapy to reduce the risk of blood clots and statin drugs to lower cholesterol and advise PAD patients to participate in a structured exercise program. [More]
Study of new polymer-free DFS indicates non-inferior in-stent late lumen loss at nine-months

Study of new polymer-free DFS indicates non-inferior in-stent late lumen loss at nine-months

A first-in-human study of a new polymer-free drug-filled stent, which provides controlled drug elution from an internal lumen, indicated non-inferior in-stent late lumen loss at nine-months compared with historical zotarolimus-eluting stent (Resolute) data. In addition, there was no binary restenosis, and a high degree of early stent strut coverage with minimal malapposition. [More]

TCT 2016 features first report investigations on novel bioresorbable stents

The 28th annual Transcatheter Cardiovascular Therapeutics (TCT), the annual scientific symposium of the Cardiovascular Research Foundation featured a number of first report investigations on novel stents that could become the next generation of bioresorbable stents in patients. [More]
Stents can be as effective as surgery for many patients with left main coronary artery disease

Stents can be as effective as surgery for many patients with left main coronary artery disease

A major international study has found that drug-eluting stents, a less-invasive alternative to bypass surgery, are as effective as surgery for many patients with a blockage in the left main coronary artery. [More]
OCT offers safe and better guidance for patients undergoing PCI to treat coronary artery disease

OCT offers safe and better guidance for patients undergoing PCI to treat coronary artery disease

Optical coherence tomography (OCT) provides safe and improved guidance for patients undergoing percutaneous coronary intervention to treat coronary artery disease, according to results from the ILLUMIEN III: OPTIMIZE PCI trial. [More]
Adherence to medical therapy linked to better outcomes for patients who had heart procedures

Adherence to medical therapy linked to better outcomes for patients who had heart procedures

Patients who had a stent procedure or heart bypass surgery and continued with their prescribed medical therapy had significantly better outcomes than non-adherent patients, according to a study published today in the journal Circulation. [More]
Scientists use 3-D printing to develop customized biodegradable stents

Scientists use 3-D printing to develop customized biodegradable stents

Most people have heard about personalized medicine. But how about personalized medical devices? Northwestern Engineering's Guillermo Ameer and Cheng Sun have teamed up to use 3-D printing to develop flexible, biodegradable stents that are customized for a specific patient's body. [More]
UCLA-led study shows treatment can provide benefits up to 7.3 hours after onset of stroke

UCLA-led study shows treatment can provide benefits up to 7.3 hours after onset of stroke

Time is of the essence when getting people stricken with acute ischemic strokes to treatment. And the use of stent retrievers — devices that remove the blood clot like pulling a cork out of a wine bottle — has proven to be a breakthrough for removing the life-threatening blockage of blood flow to the brain.

New study suggests major change in treatment of significant number of ACS patients

More than one quarter of heart attack patients who are normally treated with stents to re-open their blocked arteries might be able to forgo this procedure and receive anti-thrombotic medications only, according to results of a pilot study. [More]

BBK II trial compares two commonly used stenting techniques for coronary bifurcation

Coronary bifurcations - a type of coronary artery narrowing - are best treated with a technique known as culotte stenting, as opposed to T-and-protrusion (TAP) stenting, when there is need for a side-branch stent according to results of the BBK II (Bifurcations Bad Krozingen) trial. [More]
