      Head-to-head comparison of quantitative measurements between intravascular imaging systems: An in vitro phantom study

      Introduction The present study aimed to compare the accuracy of quantitative measurements by contemporary intravascular imaging systems including optical frequency domain imaging (OFDI), frequency domain optical coherence tomography (FD-OCT), and 6 intravascular ultrasound (IVUS) systems. Methods We imaged five cylindrical phantom models made from an acrylic resin with known lumen diameters (1.51, 2.03, 3.04, 4.04, and 5.04 mm, respectively) using OFDI (FastView and LUNAWAVE, Terumo), FD-OCT (Dragonfly JP and ILUMIEN OPTIS, Abbott Vascular), and 6 mechanically rotating IVUS systems including a system, two 40-MHz, one 45-MHz, two 60-Mhz and one broad-band frequency IVUS systems. The ...

      In-stent accordion phenomenon

      A 60-year-old female underwent successful stenting of the proximal to distal right coronary artery (RCA). Follow-up angiography was performed 16 months after the index procedure. It revealed moderate in-stent restenosis in the mid-RCA (Fig. 1A). Optical coherence tomography (OCT) was performed to evaluate it. After insertion of the guidewire (SION blue, Asahi Intecc, Nagoya, Japan) into the distal RCA, a short-segment stenosis appeared in the proximal RCA where zotarolimus-eluting stents (Resolute integrity, Medtronic, Minneapolis, MN) were implanted (Fig.
