Figure 2 Scanning Electron Micrographs of 14-Day Comparator DES and BMS Controls
The upper panels show corresponding radiographic images of each stent. The lumens are clearly patent and struts are easily discerned underneath a thin neointimal surface. Among DES, there is less endothelial cell surface coverage in SES and PES stents compared with ZES and EES. The panel insets are representative images at higher magnification (x200) from proximal and distal regions showing bare struts, surface thrombi, inflammatory cells, and endothelial cells. Abbreviations as in Figure 1.
