We performed a study level pooled analysis from the five largest registries of percutaneous coronary intervention (PCI) of CTO. Research design and methods We conducted pooled analysis of 9500 patients in registries and data on procedural characteristics, technical success, and MACCE was collected. Results A total of 9500 patients were included in the analysis. Mean age was 65.4 years with previous CABG in 24.8%, reattempt procedure in 24.8% and mean JCTO score was 2.2.
