Abstract
- Background--The performance of the Japan-chronic total occlusion (J-CTO) score in predicting success and efficiency of CTO percutaneous coronary intervention has received limited study. Methods and Results--We examined the records of 650 consecutive patients who underwent CTO percutaneous coronary intervention between 2011 and 2014 at 6 experienced centers in the United States. Six hundred and fifty-seven lesions were classified as easy (J-CTO=0), intermediate (J-CTO=1), difficult (J-CTO=2), and very difficult (J-CTO=3). The impact of the J-CTO score on technical success and procedure time was evaluated with univariable logistic and linear regression, respectively. The performance of the logistic regression model was assessed with the Hosmer-Lemeshow statistic and receiver operator characteristic curves. Antegrade wiring techniques were used more frequently in easy lesions (97%) than very difficult lesions (58%), whereas the retrograde approach became more frequent with increased lesion difficulty (41% for very difficult lesions versus 13% for easy lesions). The logistic regression model for technical success demonstrated satisfactory calibration and discrimination (P for Hosmer-Lemeshow =0.743 and area under curve =0.705). The J-CTO score was associated with a 2-fold increase in the odds of technical failure (odds ratio 2.04, 95% confidence interval 1.52-2.80, P<0.001). Procedure time increased by 20 minutes for every 1-point increase of the J-CTO score (regression coefficient 22.33, 95% confidence interval 17.45-27.22, P<0.001). Conclusions--J-CTO score was strongly associated with final success and efficiency in this study, supporting its expanded use in CTO interventions. [ABSTRACT FROM AUTHOR]
