Abstract: Background: Several scoring systems have been described to assess the level of difficulty and to predict the probability of success of percutaneous coronary intervention (PCI) of chronic total occlusion (CTO). The J-CTO score was initially developed to correlate CTO complexity with guidewire time crossing through the lesion within 30 min. Moreover, almost all scoring systems represent procedures performed by seasoned operators. Herein, this study sought to evaluate the predictive capacity of J-CTO for PCI success in a European single-center cohort with growing experience in the approach of CTO. Methods: Five hundred twenty-six procedures were performed between 2007 and 2020 mainly by a single operator. The predictive power of J-CTO score was assessed by area under the receiver-operator characteristic curve (ROC) in the entire cohort and additionally in two separate periods. The goodness-of-fit of the model was evaluated by the Hosmer and Lemeshow statistic. Results: Successful procedure in first-attempt PCI was 79.5% and the overall success including 47 repeated procedures was achieved in 85.8%. The retrograde approach was attempted in 14.4%. The score was inversely associated with procedural success with lower success rate in more difficult CTOs (p < 0.001). ROC curve for the entire cohort, and first block (case 1–200) and second block (case 201–526) was 0.696, 0.661 and 0.748, respectively. The model showed good calibration for the entire cohort (X2 = 1.7; p = 0.43). Conclusions: J-CTO score showed an acceptable predictive power for procedural success in this cohort although its discriminatory power is better as the level of experience is improved.
