NCT03209843

Brief Summary

The objective of PERFECTO is to assess the reendothelialization at 3 months after successfully CTO percutaneous intervention (PCI) with new generation drug eluting stent (DES) by OFDI analysis. Designed as a multicentric, observational and prospective study which will be conducted at University Hospital of Poitiers (France), a systematic OFDI analysis will be realized immediately after CTO-PCI and at 3 months. Known as major predictive factors of stent thrombosis, percentages of malapposition, uncovered struts and neointimal hyperplasia proliferation will be measured over the entire length of each stent implanted combining in a composite primary endpoint.

Outcome Measures

Primary Outcomes (7)

  • Percentage of uncovered stent struts

    Measured by OFDI 3 months after CTO recanalization every millimeter over entire length of each stent implanted. (Number uncovered struts x 100)/total number of struts.

    3 months

  • Percentage of malapposed stent struts

    Measured by OFDI 3 months after CTO recanalization every millimeter over entire length of each stent implanted. (Number of malapposed struts x 100)/total number of struts.

    3 months

  • Percentage of neointimal hyperplasia proliferation

    Measured by OFDI 3 months after CTO recanalization every millimeter over entire length of each stent implanted. \[(minimal stent area - minimal lumen area)/minimal stent area\]x100.

    3 months

  • Minimal lumen area

    Measured by OFDI 3 months after CTO recanalization every millimeter over entire length of each stent implanted.

    3 months

  • Minimal lumen diameter

    Measured by OFDI 3 months after CTO recanalization every millimeter over entire length of each stent implanted

    3 months

  • Thrombus

    Measured by OFDI 3 months after CTO recanalization every millimeter over entire length of each stent implanted.

    3 months

  • Edge dissection

    Measured by OFDI 3 months after CTO recanalization every millimeter over entire length of each stent implanted.

    3 months
