What does a drug-eluting stent do?

A stent is a small mesh tube inserted into an artery to keep it open. A drug-eluting stent is coated with a slow-release medication to help prevent blood clots from forming in a stent. Blood clotting in a stent can cause a future blockage (restenosis) and may lead to a heart attack.

How long does the drug last in a drug-eluting stent?

Conclusions. Our study findings suggest that the long-term survival (to 3 years) of patients with drug-eluting stents remains favourable overall. It is not measurably worse than that of patients with bare-metal stents.

Is self expanding stent drug-eluting?

The use of third-generation drug-eluting stents (DES) is currently the preferred method of treatment for different indications in patients with coronary artery disease. Self-expanding stents are routinely used in peripheral arterial disease, like external iliac and femoropopliteal percutaneous interventions.

How do self expanding stents made from nitinol work?

Nitinol stents are manufactured to a size slightly larger than the target vessel size and delivered constrained in a delivery system. After deployment, they position themselves against the vessel wall with a low, “chronic” outward force. They resist outside forces with a significantly higher radial resistive force.

What are self expanding stent?

Self-Expandable Stents. Self-expanding stents are constrained within a delivery catheter until positioned and deployed. Because no balloon is needed to deploy the stent, the delivery devices are generally smaller than balloon-expandable stent systems.

Why do drug eluting stents require longer antiplatelet therapy?

1 Drug eluting stents (DES) are usually preferred over bare metal stents (BMS) because of less restenosis and fewer repeat revascularization procedures. However, DES require a longer duration of dual antiplatelet therapy to minimize the chance of stent thrombosis.

Are drug eluting stents better than bare metal?

The use of drug-eluting stents has been shown to be more effective in the prevention of restenosis than the use of bare-metal stents,1 and the use of newer-generation drug-eluting stents, as compared with first-generation devices,3,4 may also reduce the rate of stent thrombosis.

How are drug eluting stents used in cardiology?

The recent introduction of drug-eluting stents (DES) contributes a major breakthrough to interventional cardiology. Many large randomized clinical trials using DES have shown a remarkable reduction in angiographic restenosis and target vessel revascularization when compared with bare metal stents.

Are there any drug eluting stents for Kawasaki disease?

Aetna considers FDA-approved drug eluting stents medically necessary for treatment of coronary lesions in Kawasaki disease.

When to use Xience V and Xience nano everolimus?

How are Taxus Express paclitaxel eluting stents used?

The FDA approved the paclitaxel-eluting stents (Taxus Express Paclitaxel-Eluting Coronary Stent System, Boston Scientific Corporation) for improving luminal diameter for the treatment of de novo lesions less than 28 mm in length in native coronary arteries greater than or equal to 2.5 to less than or equal to 3.75 mm in diameter.
