The purpose of the study is 1> to compare neointimal stent coverage after OCT-guided vs. Angio-guided PCI, 2> to compare neointimal stent coverage at 3 months after EES (Xience Prime®) vs N-BES (Nobori®) implantation, and 3> to determine the duration of dual antiplatelet therapy by OCT measurement at 3 months.
