Objectives: The J-CTO score is based on invasive angiography, combines several parameters of chronic total coronary occlusions (CTO), and is well established to predict the likelihood of success of percutaneous recanalization. The purpose of this study was to evaluate and validate a J-CTOCT score derived from coronary computed tomography angiography (coronary CTA).

Methods: Between April 2011 and December 2014, 159 consecutive patients were retrospectively included. All had at least one CTO in invasive angiography, had coronary CTA performed at an interval of no more than one week from invasive angiography, and had an attempt at percutaneous coronary intervention (PCI) following coronary CTA In parallel to the angiographic J-CTO score, the J-CTOCT score was determined by awarding one point each for a blunt vessel stump, bending > 45°, occlusion length ≥ 20 mm, presence of calcium covering > 50% of any vessel cross-section within the occlusion, or a previously failed attempt at PCI. a. Both scores were compared regarding their ability to predict successful recanalization.

Results: A total of 171 CTO lesions were analyzed. Intraobserver (k = 0.814, p < 0.001) and interobserver agreement (k = 0.771, p < 0.001) for calculation of the J-CTOCT score were close. The mean occlusion length measured by coronary CTA was significantly shorter than in invasive angiography (27.6 ± 14.8 mm vs. 37.2 ± 18.8 mm, p < 0.001). The J-CTOCT score (mean: 1.9 ± 1.4) correlated closely to the angiographic J-CTO score (mean: 1.8 ± 1.3, r = 0.856, p < 0.001), and in 122/171 lesions (71%), the scores were identical. Both J-CTOCT score (area under curve: 0.882, p < 0.001) and angiographic J-CTO score (area under curve: 0.868, p < 0.001) yielded similarly high predictive value for successful guidewire crossing within 30 min (p = 0.496).

Conclusions: While the length of coronary occlusions in coronary CTA is significantly shorter than in invasive angiography, a J-CTOCT score determined by coronary CTA closely correlates to the angiographic J-CTO score. .
