Incidence and distribution of thin-high signals detected by coronary optical coherence tomography in patients treated with paclitaxel-coated balloon angioplasty for in-stent restenosis
Paclitaxel-coated balloon (PCB) angioplasty is one of the common treatments for patients with in-stent restenosis because its safety and efficacy has already been reported [1–3]. Meanwhile, optical coherence tomography (OCT) has great spatial resolution, which allows the observation of subtle changes in the coronary artery [4,5]. In a previous report, thin-high signals after PCB angioplasty were observed using OCT . However, the incidence and distribution of thin-high signals have yet to be investigated.
