Figure 3

SEM of overlapping 28-day BxVelocity (A), Cypher (B-F), Express (G), and Taxus (H-L) stents. Regions of overlap are within horizontal arrows. There is less surface coverage by endothelial cells on Taxus than Cypher stents, specifically in segments of overlap. Overlapping segments within BxVelocity and Express stents showed far greater endothelialization than DES. Higherpower views of Cypher stents (C-F) from segment of overlap show adherent platelets and inflammatory cells on stent struts and adjoining neointima. Higherpower images from overlapping segments of Taxus stents (I-L) show greater inflammatory infiltrate (I), polymer sticking and stretching across stent struts (J, arrow), unexpanded struts (K, arrow), and irregular distribution of the polymer over stent strut surface (L, arrowheads) (Reproduced with permission from39).
