    Analysis of Long-term Arterial Healing Following Implantation of Different Types of Stents by Optical Coherence Tomography

    Background Although drug-eluting stents have significantly reduced the mid-term incidence of target lesion revascularization, however, in vivo studies on long-term vessel healing of sirolimus-eluting and paclitaxel-eluting stents (SES and PES) are limited. So the aim of this study was to compare long-term arterial healing in SES and PES. Methods We evaluated 27 SES (23 patients) and 21 PES (20 patients) by serial optical coherence tomography (OCT) at 6 months (mid-phase) and ≥3 years (late-phase) after stenting and evaluated the change of neointimal thickness (NIT), the percentages of uncovered and malapposed struts, peri-strut low intensity area (region around stent struts homogenously ...
