Visual Abstract
Highlights • Restenosis limits the efficacy of PTA or stent treatment of atherosclerosis in peripheral and coronary artery disease. • Paclitaxel DCBs effectively reduce restenosis; however, recently, their overall safety profile has been called into question. • In an in vivo molecular-structural imaging study of 25 rabbits with experimental atherosclerosis, DCB-PTA, plain PTA, or sham-PTA was investigated using serial intravascular NIRF-OCT and IVUS. • DCB-PTA reduced lesion inflammation on NIRF-OCT and halted lesion progression on IVUS, compared with PTA or sham-PTA. • These findings indicated the potential for DCBs to serve effectively and safely as a regional anti-atherosclerosis therapy.
Summary Paclitaxel drug-coated balloons (DCBs) reduce restenosis, but their overall safety has recently raised concerns. This study hypothesized that DCBs could lessen inflammation and reduce plaque progression. Using 25 rabbits with cholesterol feeding- and balloon injury-induced lesions, DCB-percutaneous transluminal angioplasty (PTA), plain PTA, or sham-PTA (balloon insertion without inflation) was investigated using serial intravascular near-infrared fluorescence−optical coherence tomography and serial intravascular ultrasound. In these experiments, DCB-PTA reduced inflammation and plaque burden in nonobstructive lesions compared with PTA or sham-PTA. These findings indicated the potential for DCBs to serve safely as regional anti-atherosclerosis therapy.
