Accuracy of the Euro CTO(CASTLE) score obtained on coronary computed tomography angiography for Predicting 30-minute wire crossing in chronic total occlusions.

Background: To investigate the feasibility and accuracy of the Euro CTO (CASTLE) score obtained on coronary computed tomography angiography (CCTA) for predicting the success of percutaneous coronary intervention (PCI) and the 30-min wire crossing in chronic total occlusions (CTO).

Method: One hundred and fifty patients (154 CTO cases; median age, 61 (interquartile range [IQR], 54-68) years; 75.3% male) received CCTA at the People's Hospital of Liaoning Provincce within 1 month before the procedure.
