Legend. Scanning electron micrographs and corresponding radiographic images (upper panels) comparing endothelial coverage of DES and BMS Vision controls at 28 days. The lumen are patent and struts are weakly discernable under the neointima. Overall endothelial coverage is near complete in all DES. The higher magnification inserts from the proximal and distal regions show persistent uncovered struts, surface thrombi, inflammatory cells, and endothelial cells. See page 337.
