Tip detection-antegrade dissection and reentry (TD-ADR) with integrated fluoroscopic and intravascular ultrasound images in chronic total occlusion: first case report of integrated TD-ADR technique

Tip detection-antegrade dissection and re-entry (TD-ADR) technique allows operators to accurately observe both guidewire tip direction and a true lumen in chronic total occlusion (CTO) lesions, while the torque direction of the guidewire on IVUS images does not invariably correspond to that on fluoroscopic images.
