Primary Outcome Measures:
  • Proportion of uncovered and/or malapposed Taxus Libertè struts at different time point after the implant, as measured by OCT [ Time Frame: 3-6-9 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • % Incomplete apposition at different point of FU (3-6-9 months) [ Time Frame: 3-6-9 months ] [ Designated as safety issue: Yes ]
  • Proportion of neointima disomogeneity around struts at different point of FU (3-6-9 months) [ Time Frame: 3-6-9 months ] [ Designated as safety issue: Yes ]
  • OCT Neointima thickness overtime [ Time Frame: 3-6-9 months ] [ Designated as safety issue: No ]
  • Ischemia Driven Target Vessel Failure (ID-TVF) rate at 12 months [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
  • Adjudicated MACE rate at 30 days and 12 months [ Time Frame: 30 days and 12 months ] [ Designated as safety issue: Yes ]

Detailed Description:

Major concerns were addressed to the delayed healing process of drug-eluting stents in off-label indications. To date no studies have detailed the in-vivo completeness of DES coverage at different time points. The objective of this prospective study is to measure the completeness of strut coverage and vessel wall response (neointima disomogeneity, acquired late incomplete strut apposition) at different time points following paclitaxel-eluting stent implantation, in patients with multivessel disease treated with staged PCI procedures. Optical Coherence Tomography (OCT) that detects smaller degrees of stent strut coverage more accurately than IVUS will be used at different time point. Intravascular ultrasound (IVUS) will be performed as per normal practice at any index procedures and 9 months elective follow-up.
