Stent News and Research RSS Feed - Stent News and Research

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 multi-tasking stent could reduce risks associated with coronary artery procedure

New multi-tasking stent could reduce risks associated with coronary artery procedure

Every year, an estimated half-million Americans undergo surgery to have a stent prop open a coronary artery narrowed by plaque. But sometimes the mesh tubes get clogged. Scientists report in the journal ACS Nano a new kind of multi-tasking stent that could minimize the risks associated with the procedure. [More]

Survey: 52% of acute coronary syndrome patients don't take their prescribed OAP therapy

People with acute coronary syndrome (ACS) who undergo an angioplasty procedure and receive a heart stent are prescribed an oral antiplatelet (OAP) therapy and aspirin to help prevent a heart attack, a blood clot in their heart stent (stent thrombosis), or even death. [More]

Endovascular therapy best treatment option for stroke patients

A research paper published in the New England Journal of Medicine (NEJM) today confirms earlier findings that a procedure called endovascular therapy (ET) for ischemic stroke is the best treatment option for many patients by reducing the incidents of disability. [More]

Medtronic plans to develop stent graft system for treatment of thoracoabdominal aortic aneurysms

The global leader in medical technology for endovascular aortic repair (EVAR), Medtronic plc today announced that it plans to develop a stent graft system for less invasive treatment of thoracoabdominal aortic aneurysms under an exclusive patent license agreement with South Dakota-based Sanford Health.

New stent retriever device reduces stroke damage

New stent retriever device reduces stroke damage

Elizabeth Celli was experiencing a moderate-to-severe stroke when she arrived at Loyola University Medical Center's Emergency Department. Mrs. Celli was weak on her left side, had difficulty speaking and was unable to walk. But after being treated with a new device called a stent retriever, her symptoms dramatically reversed. [More]
Use of balloon-expandable stent compared with medical therapy increases stroke risk

Use of balloon-expandable stent compared with medical therapy increases stroke risk

Among patients with symptomatic intracranial arterial stenosis (narrowing of an artery inside the brain), the use of a balloon-expandable stent compared with medical therapy (clopidogrel and aspirin) resulted in an increased of stroke or transient ischemic attack (TIA), according to a study in the March 24/31 issue of JAMA.

Cardiac catheterization performed through wrist can reduce bleeding, lower mortality

Cardiac catheterization performed through wrist can reduce bleeding, lower mortality

The groin is the usual access point for investigating or treating the heart with a catheter, but using the wrist as access point reduces bleeding and lowers mortality. These findings are from an international study with major involvement from the University of Bern published today in the Lancet. [More]
Extended dual antiplatelet therapy after DES implantation increases mortality

Extended dual antiplatelet therapy after DES implantation increases mortality

Data from a meta-analysis published today in The Lancet found that extended duration dual antiplatelet therapy (DAPT) after drug-eluting stent (DES) implantation was associated with significantly higher rates of mortality compared to shorter DAPT. [More]
Patients who experience deadliest form of heart attack may benefit from angioplasty

Patients who experience deadliest form of heart attack may benefit from angioplasty

Patients who experience the deadliest form of heart attack--ST segment elevation myocardial infarction (STEMI)--and suffer from substantial narrowing in multiple heart arteries may benefit from receiving angioplasty in constricted arteries not affected by the heart attack, thereby reducing the need for future angioplasty, according to research presented at the American College of Cardiology's 64th Annual Scientific Session.

New drug fails to prevent irreversible injury to the heart after angioplasty

New drug fails to prevent irreversible injury to the heart after angioplasty

Patients who received the new drug Bendavia before undergoing angioplasty or receiving a stent to clear blocked arteries after a heart attack showed no significant reduction in scarring as compared to patients given a placebo, according to a study presented at the American College of Cardiology's 64th Annual Scientific Session. [More]
Routine use of thrombectomy in heart attack patients may increase risk of stroke

Routine use of thrombectomy in heart attack patients may increase risk of stroke

The largest study ever of its kind, led by researchers from McMaster University and the University of Toronto, has found that a routine strategy of blood clot removal during treatment for heart attacks was not beneficial and was associated with an increased risk of stroke. [More]

Patients with multiple narrowed arteries have better outcomes with CABG than with PCI

Despite the advent of a new generation of stents, patients with multiple narrowed arteries in the heart who received coronary artery bypass grafting fared better than those whose arteries were opened with balloon angioplasty and stents in a study presented at the American College of Cardiology's 64th Annual Scientific Session.
