Catastrophic Thrombus Formation During Optical Coherence Tomography

“…Therefore, balloon occlusion of the proximal vasculature for as long as 30 to 40 seconds is required. 1 This limitation can provoke myocardial ischemia during the procedure and, in rare situations, intracoronary thrombus formation as demonstrated in this case.…”

“…1 Because the resolution of OCT imaging is higher than that of IVUS, its application in research is expanding. 2,3 In particular, attempts to detect vulnerable plaques in vivo with OCT imaging and studies of the delicate interaction between vessel wall and stent strut, as well as of neointima growth, are actively ongoing.…”

Assessment of Structural and Functional Pulmonary Vascular Disease in Patients with PAH

“…OCT produces accurate images of the arterial lumen and the lumen-vessel wall interface. Normal arteries show a clear demarcation between tunica intima (highly reflective), tunica media (poorly reflective) and tunica adventitia (highly reflective) by OCT (Regar et al, 2003) (Fig. 8).…”

“…As the speed of light is much faster than that of sound, an interferometer is required to measure the backscattered light (Regar et al, 2003;Farooq et al, 2009;Pratty et al, 2010). OCT produces accurate images of the arterial lumen and the lumen-vessel wall interface.…”

Treatment of Chronic Total Occlusions Using the Avinger Ocelot Crossing Catheter

“…OCT technology uses near-infrared light to optimize intravascular visualization, and has been extensively studied for coronary arterial circulation imaging as well as plaque characterization. 6 Ocelot's optical image resolution is 10 μm, and incorporates 1,024 A-lines per image. These capabilities enable differentiation between various healthy arterial structures including media and adventitia (layered structures), and diseased arterial walls including plaque (nonlayered structures).…”
