Outcome Measures
Primary Outcome Measures
- Evaluation by QCA (Quantitative Coronary Angiography) of in-stent late loss after the implantation of the stent XIENCE V® [9 months]
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 [9 months]
- Evaluation by IVUS of the mean volume of neointimal hyperplasia after the implantation of a XIENCE V® stent [9 months]
- Evaluation by QCA of the in-stent binary restenosis rate [9 months]
- Evaluation of the in-segment binary restenosis rate [9 months]
- Evaluation by QCA of in-segment late loss [9 months]
- Evaluation by IVUS of the in-segment % volume obstruction after the implantation of the XIENCE V® stent [9 months]
- Evaluation by IVUS of the rate of late incomplete apposition [9 months]
- Document the number of confirmed stent thrombosis [1, 8, 9, 12 and 24 months]
- -Document the number of confirmed revascularizations (TLR, TVR) [1, 8, 9, 12 and 24 months]
- Document the rate of MACE [1, 8, 9, 12 and 24 months]
