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.

FDA announces recall of heart pumps linked to deaths and injuries

A pair of heart devices linked to hundreds of injuries and at least 14 deaths has received the FDA's most serious recall, the agency announced Monday.

Preventive PCI reduces cardiac event risks in patients with high-risk plaque

People with a buildup of fatty atherosclerotic plaque in the heart's arteries considered at risk of rupturing were far less likely to suffer a serious cardiac event if they underwent percutaneous coronary intervention (PCI), a procedure to open blocked arteries, compared with those who took medications alone but did not undergo PCI, according to research presented at the American College of Cardiology's Annual Scientific Session.

Novel cholesterol removal strategy shows potential benefits post-heart attack

The first trial of a novel strategy for removing cholesterol from patients' arteries did not reduce the risk of death, heart attack or stroke within three months of a prior heart attack, according to research presented at the American College of Cardiology's Annual Scientific Session. However, the findings suggest that the strategy may be beneficial with longer follow-up.

Intravascular imaging during PCI in heart disease patients improves survival, reduces adverse outcomes

Using intravascular imaging to guide stent implantation during percutaneous coronary intervention (PCI) in heart disease patients significantly improves survival and reduces adverse cardiovascular events compared to angiography-guided PCI alone, the most commonly used method.

OCT-guided PCI does not reduce target vessel failure in complex patients, but improves safety

Optical coherence tomography (OCT)-guided percutaneous coronary intervention (PCI) leads to a larger minimum stent area but does not reduce the two-year rate of target vessel failure compared with angiography-guided PCI, according to late breaking research presented in a Hot Line session today at ESC Congress 2023.

Dual-antiplatelet therapy should remain the standard strategy for PCI even in the drug-eluting stent era

Prasugrel monotherapy after percutaneous coronary intervention (PCI) with drug-eluting stents is not superior to dual-antiplatelet therapy (DAPT) for major bleeding but is non-inferior for cardiovascular events in patients with acute coronary syndrome (ACS) or high bleeding risk (HBR), according to late breaking research presented in a Hot Line session today at ESC Congress 2023.
