Background
Drug-coated balloons (DCBs) have shown efficacy for treatment of coronary artery disease. In the PEPCAD II ISR trial, paclitaxel-coated balloon (PCB) reduced in-stent restenosis (ISR) compared with paclitaxel-eluting stent (PES). Here we evaluated the efficacy of PCB in a porcine ISR model.
Materials and methods
Thirty-two coronary arteries (LAD: n =12, LCX: n =11, RCA: n =9) of 24 Yorkshire pigs were assigned to two groups randomly. PCB (SeQuent, length 20 mm, n =16) or noncoated balloon (NCB, length 20 mm, n =16) was inflated for 60 s with B:A 1.2:1 followed by BMS (length 12 mm) implantation (S/A 1.5:1) within the target region. At 28 days, animals underwent restudy for the assessment of quantitative coronary angiography (QCA) and optical coherence tomography (OCT).
