Neointimal Characteristics after Everolimus-Eluting Stents Implantation for Chronic Total Occlusion: An Optical Coherence Tomographic Study
نویسندگان
چکیده
Methods: We divided our patients (35 EESs) into three groups: patients with stenting for non-CTO lesions (non-CTO group), patients with subintimal stenting (CTO subintima group) and with intra true-lumen stenting for CTO lesions (CTO true lumen group). We compared OCT parameters included the percentage of neointimal hyperplasia area obstruction (%NHAO), mean neointimal hyperplasia (NIH) thickness, the proportion of uncovered struts, the proportion of malapposed struts at cross sectional level and at strut level among three groups.

Comparison of Neointimal Tissue Characteristics Between Bare-metal and Second-generation Drug-eluting Stents Nine Months after Implantation in Patients with ST-segment Elevation Myocardial Infarction
Background: Neointimal tissue characteristics after implantation of stents are related to late/ very late stent thrombosis and/ or restenosis of target lesion. However, the difference of them has not been fully elucidated among bare-metal stents (BMS) and second-generation drug-eluting stents (DES). Methods: The present study uses optical coherence tomography (OCT) to compare neointimal tissue ...

Background Previous clinical trials have demonstrated the clinical and angiographic superiority of everolimus-eluting stents (EES) compared with paclitaxel-eluting stents (PES) in the small coronary vessel. However, the differences of vascular response including assessment of morphological neointimal tissue (NIT) characteristics using optical coherence tomography (OCT) have not been fully evalu...

PURPOSES The serial changes in neointimal tissues were compared between everolimus-eluting stent (EES) and bare-metal stent (BMS) in the porcine coronary artery using optical coherence tomography (OCT). METHODS Serial (1, 3, and 6 month follow-up after stent implantation) OCT examinations were performed in 15 swine with 15 BMS- and 15 EES-treated lesions in porcine coronary arteries. RESULT...
متن کاملComparison of Optical Coherence Tomographic Assessment between First- and Second-Generation Drug-Eluting Stents
PURPOSE There is a lack of sufficient data in comparison of optical coherence tomographic (OCT) findings between first- and second-generation drug-eluting stents (DES). Compared to first-generation (i.e., sirolimus- or paclitaxel-eluting stents), second-generation DESs (i.e., everolimus- or biolinx-based zotarolimus-eluting stents) might have more favorable neointimal coverage. MATERIALS AND ...

OBJECTIVES We performed this study to investigate the vascular response in early period after zotarolimus-eluting stent (ZES) (Endeavor Sprint, Medtronic CardioVascular, Minneapolis, Minnesota) implantation. BACKGROUND The ZES has different characteristics, with biocompatible polymer and rapid drug-elution, compared with the first-generation drug-eluting stents (DES). METHODS The ENDEAVOR O...
