Receiver operating characteristic curves for CCW times as a Cutoff for predicting success and complications in CTO-PCI. Receiver operating characteristic (ROC) curves demonstrating the use of collateral channel wiring (CCW) time as a cutoff for predicting (A) CCW success, (B) technical failure, and (C) collateral channel perforation. The optimal cutoff values are indicated by the arrows: 28.5 min for both CCW success and technical failure, and 24.5 min for collateral channel perforation. CCW, collateral channel wiring; CTO-PCI, chronic total occlusion-percutaneous coronary intervention.
