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.

One stent may be as good as two

Cardiologists increasingly use non-invasive methods to treat patients with diseased arteries that previously required open-heart surgery.

New procedure for treating esophageal perforations

A new procedure can now treat esophageal perforations (holes in the esophagus) when caught early, therefore greatly reducing mortality rates.

Clopidogrel reduces risk of adverse events for patients with acute coronary syndromes undergoing balloon angioplasty

Patients with acute coronary syndromes who were pre-treated with the anti-platelet agent clopidogrel before undergoing a procedure such as balloon angioplasty or stent placement had a reduced risk of adverse events if they received the anti-clotting drug abciximab

B vitamins and folic acid don't cut the risk of further heart attacks

Scientists have found that levels of the amino acid homocysteine may be high in people destined for a heart attack or stroke, and some studies in the past have linked homocysteine to an increased risk of heart disease.

Sirolimus-releasing stents more effective than vascular brachytherapy for treating restenosis within a stent

David R. Holmes, Jr., M.D., of Mayo Clinic, Rochester, Minn., and colleagues with the SISR trial compared the use of vascular brachytherapy (VBT - intra-coronary radiation therapy) with implantation of the sirolimus-eluting stent for the treatment of restenosis occurring within a previously placed bare-metal stent

Stents that release the drug paclitaxel to treat stenosis more effective than radiation therapy

Insertion of stents that release the drug paclitaxel to treat stenosis within an implanted bare-metal stent in a coronary artery reduces the risk of subsequent re-narrowing within the stent, when compared with treatment using intra-coronary radiation

Anxiety restricts blood flow in some patients

The fear of public speaking might cause some people to do more than just break out in a cold sweat and battle stomach-churning butterflies - it could prove to have consequences for their heart health.

Drug-eluting stents best treatment for managing coronary restenosis

In the first published trial of its kind, a multi-center clinical study has shown that drug-eluting stents outperform the current "gold standard" radiation treatment in managing coronary restenosis and in preventing further clogging of coronary arteries.

Alfuzosin may improve double-J stent related symptoms

The first indwelling endoluminal ureteral stent was described over 30 years ago and has since become a routine and indispensable urologic tool. However, the side effects and patient morbidity associated with ureteral stents are not insignificant.

Enhanced external counterpulsation (EECP) reduces angina

Patients with angina (chest pain) and left ventricular dysfunction respond very well to treatment using enhanced external counterpulsation (EECP), with little or no future heart failure events, according to researchers from the Cardiovascular Institute at the University of Pittsburgh Medical Center (UPMC).

Treatment of severe coronary artery disease with angioplasty/coronary stenting a viable alternative to bypass surgery

Severe stenosis (blockage) to the left main coronary artery - a condition commonly called a "widow-maker"- can result in sudden death. For nearly 30 years, the gold standard for treatment has been coronary artery bypass surgery (CABG).

Minimally invasive surgery okay for problems of the upper part of the aorta

Tens of thousands of Americans live with a ticking time bomb in their chests. Now, a new University of Michigan study demonstrates that many of them may not need surgery in order to defuse it.

Rush University Medical Center to use new stent specifically designed for use in the brain to reduce the threat of stroke

Rush University Medical Center is the first site in Illinois to use the first stent specifically designed for use in the brain. While it has been possible to attempt to open narrowed brain vessels using existing stents made of stainless steel and intended for use in the heart, the new Wingspan brain stent is designed to be gentler on the more fragile brain vessels.
