Stent News and Research

RSS

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.

Study of airway bypass treatment for emphysema

Researchers at Cedars-Sinai Medical Center announced today the start of the EASE (Exhale Airway Stents for Emphysema) Trial, an international, multi-center clinical trial to explore an investigational treatment that may offer a new, minimally-invasive option for those suffering with advanced widespread emphysema.

3-D plasma coating technique keeps veins and arteries open

Scientists at the University of Ulster are working on a new method of coating stents – the medical devices used to keep veins and arteries open – to prevent them blocking up.

Long-term treatment with anti-clotting drug clopidogrel improves stenting outcomes in diabetic patients

A study showing that diabetic patients who are treated with long-term anti-clotting therapy are less likely to have a heart attack or die more than a year after stenting has been named among the best research papers presented at the 30th Annual Scientific Sessions of the Society for Cardiovascular Angiography and Interventions (SCAI).

Minimally invasive treatment of chronic mesenteric ischemia

Using catheter techniques perfected in the arteries of the heart, interventional cardiologists are successfully treating chronic mesenteric ischemia, a condition akin to intestinal angina.

High-dose clopidogrel before stenting cuts heart attack risk in half

Pretreatment with double-dose anticlotting medication just before percutaneous coronary intervention (PCI) cuts the combined risk of heart attack and cardiac death by half, according to a study reported at the 30th Annual Scientific Sessions of the Society for Cardiovascular Angiography and Interventions (SCAI), May 9-12, 2007, in Orlando, FL.

Role of PCI and coronary artery bypass grafting for the treatment of patients with left main coronary artery disease

Coronary artery bypass surgery has been the preferred treatment for patients with a blockage in the left main coronary artery, the conduit that supplies blood to about two-thirds of the heart.

Bare metal stents provide a safer choice

While drug-eluting stents are effective in keeping open diseased heart arteries, they should not be used for patients who need to have non-cardiac surgery a short time after an interventional heart procedure.

Angioplasty better than drugs for preventing second heart attack

After suffering a heart attack many patients still have low blood flow to the heart tissue while experiencing no symptoms and new research suggests that angioplasty is more effective than drugs for preventing second heart attacks in this situation.

Catheter-based aortic valve replacement is set to take off

Twenty years ago, few interventional cardiologists could have imagined that during their professional careers it would be possible to replace a diseased aortic valve using catheter-based techniques, rather than open-chest surgery.

Percutaneous aortic valve replacement safe

Catheter techniques are expanding into new territory, successfully aiding in the replacement of narrowed, calcified aortic valves in patients too sick to withstand open-chest surgery.

Stent thrombosis

Over the last year, it's been rare to utter the word "stent" without at least thinking "thrombosis," an uncommon but serious complication that's been on the minds of interventional cardiologists and patients alike.

Key findings on new-generation stent

New data reported at the 30th Annual Scientific Sessions of the Society for Cardiovascular Angiography and Interventions (SCAI), offered clues to the fate of a new-generation drug-eluting stent that is vying for a place in the treatment of coronary artery disease.

New Cordis device granted Humanitarian Exemption to treat intracranial aneurysms

Cordis Neurovascular, Inc. has announced that the U.S. Food and Drug Administration has granted Humanitarian Device Exemption (HDE) approval for the CORDIS ENTERPRISE Vascular Reconstruction Device and Delivery System for use with embolic coils in the treatment of wide-neck intracranial aneurysms.

Off-label and untested use of drug-coated stents is common in U.S. practice

The off-label and untested use of drug-coated stents in the treatment of coronary artery blockage is common in U.S. practice, and ischemic complication rates are higher among patients receiving drug-coated stents for off-label indications, according to two studies in the May 9 issue of Journal of the American Medical Association.

Adverse outcomes associated with unapproved uses of drug-coated stents

Research led by a team at the Methodist DeBakey Heart Center sheds light on what happens to high-risk patients who receive drug-coated stents off-label to open clogged arteries, as reported in today's Journal of the American Medical Association (JAMA) .
