Revascularization after myocardial infarction is often achieved via percutaneous coronary intervention, which often entails stenting. Drug-eluting stents have shown benefits over bare metal stents in this setting, and a variety of drug-eluting stents are now available, including sirolimus-, paclitaxel-, and zotarolimus-eluting stents. There are studies that have compared the various drug-elutin...
PURPOSE To report the 6-month angiographic results from a prospective single-center study investigating the efficacy and outcome of sirolimus-eluting stents used for bailout after infrapopliteal revascularization of patients with critical limb ischemia (CLI). METHODS Twenty-nine patients (21 men; mean age 68.7 years) underwent infrapopliteal revascularization with bare metal stents (group B) ...
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. ...
INTRODUCTION AND OBJECTIVES Drug-eluting stents are useful for preventing restenosis, but the patho-physiological processes involved in the proliferative response after implantation are still not known in detail. The aim of this study is to compare the coronary vascular histomorphometry after implanting drug-eluting stents and bare metal stents in a swine model. METHODS Sixty stents were rand...
In percutaneous coronary interventions, drug-eluting stents (DESs) have reduced the risk of restenosis and repeat revascularization compared with bare-metal stents. The secondgeneration DESs with thinner stent struts have improved safety and efficacy compared with the first-generation DESs and has been associated with a reduced risk of late stent thrombosis. The persistence of polymer material ...

BACKGROUND Second-generation drug-eluting stents (DES) have raised the bar of clinical performance. These stents are mostly made from cobalt chromium alloy. A newer generation DES has been developed from platinum chromium alloy, but clinical data regarding the efficacy and safety of the platinum chromium-based everolimus-eluting stent (PtCr-EES) is limited, with no comparison data against the c...
AIM To compare polytetrafluoroethylene stent graft (PTFE) with sirolimus and bare metal stents in reducing in-stent restenosis in native coronary vessels in patients with acute coronary syndrome. METHODS The study included patients who underwent stent implantation in acute coronary syndrome from January 2003 to May 2004. The patients (n=119) were randomized either to stent graft group (n=40),...
BACKGROUND Everolimus-eluting and paclitaxel-eluting stents, compared with bare metal stents, reduced the risk of restenosis in clinical trials with strict inclusion and exclusion criteria. We compared the safety and efficacy of the second-generation everolimus-eluting and paclitaxel-eluting stents in real-life practice. METHODS We randomly assigned 1800 consecutive patients (aged 18-85 years...
