TCT-64 Intravascular Molecular-Structural Imaging of Arterial Permeability and Vascular Injury In Vivo: Implications for Drug-Coated Balloon Efficacy

Paclitaxel (PTX) drug-coated balloons (DCBs) are effective at reducing restenosis following endovascular arterial revascularization; however, their efficacy is limited in highly calcified/impermeable arteries. However, no in vivo tool exists to guide arterial lesion preparation prior to DCB to
