BACKGROUND Currently, endovascular treatment is indicated to treat femoropopliteal lesions ≤15 cm. However, the Achilles' heel of femoropopliteal endovascular repair remains restenosis. Paclitaxel eluting stents have shown promising results to prevent restenosis in femoropopliteal lesions compared to percutaneous transluminal angioplasty. A recently released prospective registry using a newer g...
BACKGROUND There is no consensus regarding the safety and efficacy of drug-eluting stents, as compared with bare-metal stents, in patients with ST-segment elevation myocardial infarction who are undergoing primary percutaneous coronary intervention (PCI). METHODS We randomly assigned, in a 3:1 ratio, 3006 patients presenting with ST-segment elevation myocardial infarction to receive paclitaxe...
Very late stent thrombosis occurs in patients with bare metal stent implantation, although the annual incidence is much lower than that after drug-eluting stent implantation. In-stent neoatherosclerosis with ruptured plaques and thin-cap fibroatheromas has been observed in bare metal stents. Atherosclerotic plaques harvested from patients with very late stent thrombosis and those with acute cor...
OBJECTIVE To compare the effectiveness and safety of three types of stents (sirolimus eluting, paclitaxel eluting, and bare metal) in people with and without diabetes mellitus. DESIGN Collaborative network meta-analysis. DATA SOURCES Electronic databases (Medline, Embase, the Cochrane Central Register of Controlled Trials), relevant websites, reference lists, conference abstracts, reviews, ...
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—The objective was to evaluate the role of risk factors and stent type for stent thrombosis (ST) using a large real world registry. Methods and Results—We evaluated all consecutive coronary stent implantations in Sweden from May 1, 2005, to June 30, 2007. All cases of ST, documented in the Swedish coronary angiography and angioplasty registry until September 21, 2008, were analyzed. S...
Unfortunately, the original version of this article [1] contained an error. The correct paragraph can be found below: The calculation of number of patients was not correct. It was wrote the non-inferiority margin as 0.1 mm. But it was 0.19 mm in an original document. Non-inferiority margin in previous coronary intervention studies has been set between 0.1 ~ 0.2 mm. The 0.19 mm is not irrelevant...
Previous research from our group has demonstrated arsenic trioxide eluting stents significantly reduced neointimal area and thickness compared with bare metal stents. In the present study, the anti-inflammatory effects of arsenic trioxide in vitro and arsenic trioxide eluting stents in a porcine coronary model have been explored. Sixty-five pigs underwent placement of 139 oversized stents in th...
