Increased risk of restenosis after placement of gold-coated stents: results of a randomized trial comparing gold-coated with uncoated steel stents in patients with coronary artery disease.
BACKGROUND Gold is a highly biocompatible material. Experimental evidence suggests that coating the stent with a gold layer may have a beneficial influence. In this randomized trial, we assessed whether gold-coated stents were associated with a better clinical and angiographic outcome after coronary placement. METHODS AND RESULTS Patients with symptomatic coronary artery disease were randomly...
متن کاملGold-coated NIR stents in porcine coronary arteries.
BACKGROUND As endovascular stents are altered to add functionality, eg, by adding radiopaque coatings, biocompatibility may suffer. METHODS AND RESULTS We examined the vascular response in porcine coronary arteries to stainless steel gold-coated NIR stents (7-cell, Medinol, Inc). Stents, 9 and 16 mm in length, were left bare or coated with a 7-microm layer of gold. Physical and material effec...
متن کاملRelation of intimal hyperplasia thickness to stent size in paclitaxel-coated stents.
To determine the relation of intimal hyperplasia thickness to stent size in nonpolymeric paclitaxel-coated stents, intravascular ultrasound was performed after stent implantation and at 6 months. Similar to bare metal stents, this study demonstrated that intimal hyperplasia thickness is independent of stent size. There was no deleterious effect of the increased concentration associated with usi...
متن کاملComparison of zotarolimus-eluting stents with sirolimus-eluting and paclitaxel-eluting stents: intimal hyperplasia and vascular changes assessed by volumetric intravascular ultrasound analysis.
BACKGROUND As a substudy of the large, randomized ZEST (Comparison of the Efficacy and Safety of Zotarolimus-Eluting Stent with Sirolimus-Eluting and PacliTaxel-Eluting Stent for Coronary Lesions) trial comparing first- and second-generation drug-eluting stents, we evaluated intimal hyperplasia (IH) and vascular changes using volumetric intravascular ultrasound analysis. METHODS AND RESULTS C...
متن کاملPatterns of in-stent restenosis after placement of NIR gold-coated stents in unselected patients.
The aim of this study was to assess the incidence and angiographic patterns of in-stent restenosis 6 months after the implantation of NIR gold-coated stents in an unselected patient population. One hundred and sixteen consecutive patients were treated with the implantation of 149 NIR gold-coated stents. The majority of the patients (52%) had unstable angina or acute myocardial infarction. The b...
