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

ABSTRACT:

Background

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.

Case summary

A 41-year-old man with hypertension who smokes presented with sudden onset of dyspnoea, acute heart failure, and ischaemic findings on electrocardiogram; we performed percutaneous coronary intervention (PCI) for a sub-totally occluded mid-left anterior descending artery lesion. All antegrade wiring attempts failed to enter the distal true lumen followed by subintimal tracking and re-entry technique. Since the lesion re-occluded the next day,
