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.
