Everolimus-Eluting Biodegradable Abluminal Coating Stent versus Durable Conformal Coating Stent: Termination of the Inflammatory Response Associated with Neointimal Healing in a Porcine Coronary Model
Figure 1
Representative histological and electron microscopic images of Promus PREMIER™ and Synergy™ on the 2nd day after implantation. Promus PREMIER™ (a) and Synergy™ (b) were partially covered with neointima which mainly contained abundant fibrin (black arrow head). Inflammatory cells, such as monocytes and blood cells, were aggregated, surrounding the struts of both stents (black arrow). As observed through scanning electron microscopy, Promus PREMIER™ (c) and Synergy™ (d) were partially covered with a thin tissue resembling the neointima, although their surfaces were still coarse. The scale bars are 100 µm (histological images) and 30 µm (electron microscopic images).
