Long-term assessment of a novel biodegradable paclitaxel-eluting coronary polylactide stent.
AIM The aim of this study was to assess technical feasibility, biocompatibility, and impact on coronary stenosis of a new biodegradable paclitaxel-loaded polylactide stent. Due to high rates of in-stent restenosis and permanent nature of metal stent implants, synthetic polymers have been proposed as surrogate materials for stents and local delivery systems for drugs. Paclitaxel was shown to inh...
متن کاملThe twelve-month outcome of biolimus eluting stent with biodegradable polymer compared with an everolimus eluting stent with durable polymer.
INTRODUCTION Drug-eluting stents (DES) have significantly decreased the need for repeat coronary revascularization but concerns remain regarding the safety of first and second generation DES. We compared the safety and efficacy of a biolimus-eluting stent (with biodegradable polymer) with an everolimus-eluting stent (with durable polymer) one. METHODS We performed a randomized trial to compar...
متن کاملStrut coverage and vessel wall response to a new-generation paclitaxel-eluting stent with an ultrathin biodegradable abluminal polymer: Optical Coherence Tomography Drug-Eluting Stent Investigation (OCTDESI).
BACKGROUND Polymer-coated drug-eluting stents are effective in preventing restenosis but have been associated with delayed healing and incomplete strut coverage. It is unknown whether paclitaxel-eluting stents (PES) with minimal biodegradable abluminal coating enhances strut coverage while preventing neointimal hyperplasia. Using optical coherence tomography (OCT) as a primary imaging modality,...
متن کاملRandomized Comparison of a Biodegradable Polymer Ultrathin Strut Sirolimus-Eluting Stent With a Biodegradable Polymer Biolimus-Eluting Stent in Patients Treated With Percutaneous Coronary Intervention
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 ...
متن کاملVascular response to drug-eluting stent with biodegradable vs. durable polymer. Optical coherence tomography substudy of the NEXT.
BACKGROUND The aim of the present study was to compare vascular healing response between everolimus-eluting stent (EES) and biolimus-eluting stent (BES) using optical coherence tomography (OCT). METHODS AND RESULTS In the NOBORI Biolimus-Eluting Versus XIENCE V/PROMUS Everolimus-Eluting Stent Trial (NEXT), a formal OCT substudy investigated 91 patients (55 EES-treated lesions in 48 patients a...
