Pressure Wire Guidance for Infrapopliteal Artery Interventions

Balloon angioplasty will be performed on the target infrapopliteal artery lesion to achieve an optimal procedural result, as determined by angiography. Optimal results are defined as antegrade blood flow without residual stenosis \>50% or any flow-limiting dissection.

Balloon angioplasty will be performed on the target infrapopliteal artery lesions to achieve an optimal procedural result, as determined by the pressure gradient across the target lesion. An optimal procedural result is defined as pressure gradient less than 10 mmHg, measured using a Pressure Wire.
