Objectives To inform about contemporary PCI practice of in‐stent (IS) chronic total occlusions (CTO) from a large international registry in Latin America. Background IS‐CTO represent a distinctive challenge for PCI, but literature is limited and restricted to high‐resource regions of the world. Methods Patients undergoing CTO PCI enrolled in the LATAM CTO registry from 42 centers in eight countries were included. We analyzed demographics, angiographic, procedure technique, success and postprocedural outcomes between IS‐CTO and non‐IS‐CTO PCI. Results From 1,565 patients IS‐CTO was present in 181 patients (11.5%). IS‐CTO patients had higher prevalence of diabetes and hypertension than patients without IS‐CTO. IS‐CTOs had less calcification (32.5 vs. 46.7%, p < .001), lower prevalence of a proximal branch (36.3 vs. 50.1%, p < .001), more likely to be ostial (24.4 vs. 18.1%, p = .042), were longer (28.5 vs. 25.2 mm, p = .062), and had less interventional collaterals (49.1 vs. 57.3%, p = .038) compared with non‐IS‐CTO. CTO complexity scores were similar between both groups. There was no statistically significant difference in the initial or successful strategy between IS‐CTO and non‐IS‐CTO PCI. Technical success rates remained high in IS‐CTO (86.7%) and non‐IS‐CTO (83.1%, p = .230). There was no independent association between IS‐CTO and technical success in multivariable analysis. There were no differences between IS‐CTO and non‐IS‐CTO groups for in‐hospital clinical outcomes. Conclusion In a contemporary, multicenter, and international registry from Latin America, IS‐CTO PCI is frequent and has comparable technical success and safety profile compared to non‐IS‐CTO PCI.
