IMPORTANCE The current recommendation is for at least 12 months of dual antiplatelet therapy after implantation of a drug-eluting stent. However, the optimal duration of dual antiplatelet therapy with specific types of drug-eluting stents remains unknown. OBJECTIVE To assess the clinical noninferiority of 3 months (short-term) vs 12 months (long-term) of(More)
BACKGROUND Restenosis remains an important limitation of interventional cardiology. Therefore, we aimed to determine the safety and efficacy of sirolimus (a cell-cycle inhibitor)-coated BX Velocity stents. METHODS AND RESULTS Thirty patients with angina pectoris were electively treated with 2 different formulations of sirolimus-coated stents (slow release(More)
BACKGROUND The safety and efficacy of sirolimus-eluting stenting have been demonstrated, but the outcome of patients treated with this novel technology beyond the first year remains unknown. We sought to evaluate the angiographic, intravascular ultrasound (IVUS), and clinical outcomes of patients treated with sirolimus-eluting stents 2 years after(More)
BACKGROUND We have previously reported the safety and effectiveness of sirolimus-eluting stents for the treatment of de novo coronary lesions. The present investigation explored the potential of this technology to treat in-stent restenosis. METHODS AND RESULTS Twenty-five patients with in-stent restenosis were successfully treated with the implantation of(More)
OBJECTIVES We sought to assess the safety and efficacy of the novel VESTAsync-eluting stent (MIV Therapeutics, Atlanta, Georgia) combining a stainless steel platform with a nanothin-microporous hydroxyapatite surface coating impregnated with a polymer-free low-dose of sirolimus (55 microg). BACKGROUND Durable polymers in first-generation drug-eluting(More)
BACKGROUND Despite the proven superiority of sirolimus-eluting stents (SESs) compared with bare stents in the first year after implantation, long-term outcomes of patients treated with these novel devices remain unknown. Our goal was to evaluate the clinical, angiographic, and intravascular ultrasound (IVUS) outcomes of patients treated with SESs 4 years(More)
OBJECTIVES We sought to investigate the performance and efficacy of the third-generation polymer-free Vestasync-eluting stent (VES). BACKGROUND Recent concerns regarding the long-term safety of drug-eluting stents have been raised. Synthetic polymers have been associated with intensive inflammatory response and late stent thrombosis. Newly developed, the(More)
AIM Late-acquired incomplete stent apposition (ISA) has been documented after drug-eluting stent (DES) implantation; however, its clinical role remains controversial. We sought to investigate the incidence and long-term clinical consequences of late ISA after implantation of sirolimus- (SES) or paclitaxel-eluting stent (PES) in a non-selected population. (More)
BACKGROUND In diabetic patients in the Evaluation of Platelet IIb/IIIa Inhibitor for Stenting (EPISTENT) trial, abciximab reduced target vessel revascularization by approximately 50% compared with placebo. Whether this is a result of a lower restenosis rate caused by inhibition of intimal hyperplasia remains to be defined. METHODS AND RESULTS The purpose(More)
Drug-eluting stents have been investigated as a treatment option for in-stent restenosis after bare metal stenting. However, it remains unclear whether overlapping drug-eluting stents have a toxic effect on the vessel wall. The aim of this study was to analyze the 1-year intravascular ultrasound findings after 2 overlapping sirolimus-eluting stent(More)
