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 AHA/ASA guidelines recommend stent retrievers to treat strokes in selected patients

New AHA/ASA guidelines recommend stent retrievers to treat strokes in selected patients

New devices called stent retrievers are enabling physicians to benefit selected patients who suffer strokes caused by blood clots. The devices effectively stop strokes in their tracks. [More]
UCLA cardiologists use less invasive approach to replace heart valve

UCLA cardiologists use less invasive approach to replace heart valve

Last summer, after a long career as a successful entrepreneur and a brief retirement, Richard Whitaker was helping to start another new company. Unfortunately, a serious health concern caused a couple of interruptions in his work on the new venture. One of Whitaker's heart valves wasn't working properly, which caused congestive heart failure and led to two hospitalizations within several months. [More]

New stroke treatment guidelines recommend use of stent retrievers as first-line treatment for eligible patients

Today, the American Heart Association/American Stroke Association published new stroke treatment guidelines that recommend the use of stent retriever technology – such as Medtronic plc’s SolitaireTM stent retriever device – in conjunction with the current standard of care, IV-tPA, as a first-line treatment for eligible patients.

Re-Inflating balloon after carotid stenting appears to double risk of stroke and death

Re-Inflating balloon after carotid stenting appears to double risk of stroke and death

Patients with severe blockages typically undergo surgery to scrape off the fatty deposits from the walls of the vessel, the preferred approach that carries notably lower stroke risk but is not recommended for people too sick to withstand traditional surgery... [More]
New Johns Hopkins study shows re-inflating balloon after carotid stenting fuels stroke risk

New Johns Hopkins study shows re-inflating balloon after carotid stenting fuels stroke risk

After reviewing outcomes from thousands of cases, researchers at Johns Hopkins report that patients with blocked neck arteries who undergo carotid stenting to prop open the narrowed blood vessels fare decidedly worse if their surgeons re-inflate a tiny balloon in the vessel after the mesh stent is in place.

Vascular surgeries provide relief from two debilitating conditions

Vascular surgeries provide relief from two debilitating conditions

When Carol Werkman first saw Loyola University Medical Center vascular surgeon Bernadette Aulivola, MD, she was suffering from two debilitating conditions: Every time she ate, Mrs. Werkman felt terrible abdominal pain. And whenever she walked more than a few hundred feet, her legs would begin to hurt. [More]

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]
Patients undergoing percutaneous coronary intervention at higher risk for sleep apnea

Patients undergoing percutaneous coronary intervention at higher risk for sleep apnea

Patients undergoing percutaneous coronary intervention (PCI), a coronary artery widening procedureused to treat heart disease, are at high risk for obstructive sleep apnea (OSA), according to new research presented at the 2015 American Thoracic Society International Conference. [More]
Survey: 52% of acute coronary syndrome patients don't take their prescribed OAP therapy

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]
Study confirms benefits of removing blood clots after stroke

Study confirms benefits of removing blood clots after stroke

A technique that removes blood clots from large brain blood vessels reduced disability after stroke in a trial conducted in Catalonia, Spain, and co-led by an expert from the University of Pittsburgh School of Medicine. [More]

Endovascular therapy best treatment option for stroke patients

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

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

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.
