Impact of J-CTO score on procedural outcome and target lesion revascularisation after percutaneous coronary intervention for chronic total occlusion: a substudy of the J-CTO Registry (Multicentre CTO Registry in Japan)

Abstract

Patients with CTO lesions with lower J-CTO scores are expected to achieve a high procedural success rate and an increased TLR-free survival rate. Patients with high J-CTO scores still remain an issue.
