Primary Outcome Measures:
  • Evaluation by QCA (Quantitative Coronary Angiography) of in-stent late loss after the implantation of the stent XIENCE V® [ Time Frame: 9 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Evaluation by IVUS (Intra Vascular Ultrasound) of the in-stent volume obstruction percentage (%VO) after the implantation of a XIENCE V® stent [ Time Frame: 9 months ] [ Designated as safety issue: No ]
  • Evaluation by IVUS of the mean volume of neointimal hyperplasia after the implantation of a XIENCE V® stent [ Time Frame: 9 months ] [ Designated as safety issue: No ]
  • Evaluation by QCA of the in-stent binary restenosis rate [ Time Frame: 9 months ] [ Designated as safety issue: Yes ]
  • Evaluation of the in-segment binary restenosis rate [ Time Frame: 9 months ] [ Designated as safety issue: Yes ]
  • Evaluation by QCA of in-segment late loss [ Time Frame: 9 months ] [ Designated as safety issue: Yes ]
  • Evaluation by IVUS of the in-segment % volume obstruction after the implantation of the XIENCE V® stent [ Time Frame: 9 months ] [ Designated as safety issue: Yes ]
  • Evaluation by IVUS of the rate of late incomplete apposition [ Time Frame: 9 months ] [ Designated as safety issue: Yes ]
  • Document the number of confirmed stent thrombosis [ Time Frame: 1, 8, 9, 12 and 24 months ] [ Designated as safety issue: Yes ]
  • -Document the number of confirmed revascularizations (TLR, TVR) [ Time Frame: 1, 8, 9, 12 and 24 months ] [ Designated as safety issue: Yes ]
  • Document the rate of MACE [ Time Frame: 1, 8, 9, 12 and 24 months ] [ Designated as safety issue: Yes ]
