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 ...

BACKGROUND: Treatment of in-stent restenosis of the femoropopliteal arteries with balloon angioplasty carries a high rate of recurrence and requires frequent repeat stenting. In the "Instructions for Use," SilverHawk atherectomy (SA) is contraindicated for in-stent restenosis at a peripheral site. SA, however, has a theoretical advantage of reducing the volume ...

Prior to June 2011, carotid artery stenting (CAS) had been limited to patients deemed high risk for surgical revascularization due to medical or anatomic reasons. Intraprocedural anticoagulation for CAS has traditionally been carried out with unfractionated heparin (UFH). The direct thrombin inhibitor bivalirudin has emerged as a possible alternative choice ...

There is a lack of sufficient data in comparison of optical coherence tomographic (OCT) findings between first- and second-generation drug-eluting stents (DES). Compared to first-generation (i.e., sirolimus- or paclitaxel-eluting stents), second-generation DESs (i.e., everolimus- or biolinx-based zotarolimus-eluting stents) might have more favorable neointimal coverage. Follow-up OCT findings of 103 patients ...
