  9. Percent diameter stenosis after 9 months

  10. Patterns of in-stent restenosis (Mehran classification) 10% 10% 15,8% 11,1% Restenosis rate 5,7% 0% Risk of restenosis in relation to type of lesion

  11. Comparison Among DES Trials Late Loss Comparison Among DES TRIALS Binary Restenosis (In Stent)

  12. Comparison Among DES Trials MACE

  13. Excellent procedural outcome with device success 100% • Low MACE rate over 9 months after implantation (2.7%) • Favorable late (9 months) angiographic results: - Binary restenosis 10,0% - Late loss 0.45 mm
