antegrade wire approach
Guidewire advancement technique proceeding in the forward direction of normal blood flow through coronary vessels.
Full Definition
The standard method of guidewire passage through coronary arteries, following the natural direction of blood flow from proximal to distal vessel segments. This approach is used in most percutaneous coronary interventions and contrasts with retrograde techniques that may be employed in complex cases such as chronic total occlusions. Success depends on wire selection, operator technique, and lesion characteristics including vessel tortuosity and calcification.
Usage
Usage note: Specify wire type and crossing strategy when documenting complex lesions.
