Successful revascularization of chronic total occlusion (CTO) by percutaneous coronary intervention (PCI) is associated with reduced major adverse cardiovascular events (MACEs) compared with CTO PCI failure. The developments of new strategies and new devices have improved the success rate of CTO PCI. However, the complexity of CTO lesions, clinical characteristics of patients and operator experience highly determine the successful revascularization. Using search items, “chronic total occluion”, “percutaneous coronary intervention”, “scoring systems”, “predictablity”. We searched Pubmed, ScienceDirect, Web of Science, Cochrane Library, and CNKI. We found six clinically used scoring systems from 2011 to 2018. They included J-CTO score, CT-RECTOR score, CL score, PROGRESS CTO score, ORA score, and Ellis score. All parameters of each scoring systems have been systematically reviewed. The patients with higher score have found to have adecreased probability of CTO recanalization. Ellis score that mainly focused on ambiguous proximal cap and hybrid approach seems to provide better predictability in deciding procedure strategy.
