OBJECTIVES This study sought to evaluate the outcomes of drug-eluting stent treatment for femoropopliteal in-stent restenosis (ISR). BACKGROUND ISR after femoropopliteal interventions is an increasing problem. Although the role of drug-eluting stents in the treatment of coronary ISR is well defined, no published studies have examined drug-eluting stents in the treatment of femoropopliteal ISR...

Background—Some but not all studies have reported reduced rates of stent thrombosis (ST) with everolimus-eluting stents (EES) compared with other drug-eluting stents (DES). All of these studies were insufficiently powered to reliably detect differences in ST. We therefore performed a meta-analysis of randomized controlled trials comparing the risk of 2-year definite ST between EES and other DES...

BACKGROUND Intravascular ultrasound of drug-eluting stent (DES) thrombosis (ST) reveals a high incidence of incomplete stent apposition (ISA) and vessel remodeling. Autopsy specimens of DES ST show delayed healing and hypersensitivity reactions. The present study sought to correlate histopathology of thrombus aspirates with intravascular ultrasound findings in patients with very late DES ST. ...

The majority of percutaneous coronary intervention cases are performed using drug eluting stents. Trials have consistently demonstrated lower rates of in stent restenosis and repeat revascularization with drug eluting stents when compared with bare metal stents. Stent technology has improved over the decade with changes in the thickness of stent struts, polymer coating and ease of stent deliver...

Antiproliferative drug-eluting stents represent a miles tone in advances in interventional cardiology. The amount and quality of the scientific evidence now show these new stents to be highly effective in reducing neointimal proliferation, and hence the process of restenosis. Their clinical impact can be expected to become relevant in terms of both increased indications for angioplasty and the ...

Analyst projections for the drug-eluting stent (DES) market estimated that the total number of DES implanted in 2010 would go beyond 4.5 million worldwide. Although the initial results seemed promising, longer-term follow-up in a broader range of patients revealed some pitfalls. Delayed neointimal growth, enhanced platelet aggregation, a local hypersensitivity reaction against the polymer coati...

BACKGROUND Maintaining arterial duct patency by stent implantation may be advantageous in congenital heart disease management algorithms. Rapamycin, an immunosuppressant drug that demonstrates antiproliferative properties and inhibits smooth muscle cell migration, may deter the intimal hyperplasia that occurs during spontaneous closure and after-stent implantation of the arterial duct. METHOD...

Patients listed for organ transplant frequently have severe coronary artery disease (CAD), which may be treated with drug eluting stents (DES). Everolimus and zotarolimus eluting stents are commonly used. Newer generation biolimus and novolimus eluting biodegradable stents are becoming increasingly popular. Patients undergoing transplant surgery soon after the placement of DES are at increased ...
