Figure 1 Representative OCT Images of Stented Lesions After PCI and Corresponding IVUS Images
(A-1) OCT-visualized inadequate stent strut apposition (arrows). (A-2) It was not shown clearly on IVUS. (B-1) Tissue protrusion between stent struts was observed in OCT image (arrow). (B-2) It was not evident in the IVUS image. (C-1) Intracoronary thrombi were identified as intraluminal mass images with signal-free shadow by OCT (arrows). (C-2) They were not detected by IVUS. (D-1) Coronary dissection at the site of stent edge was demonstrated by OCT (arrows). (D-2) IVUS documented dissection (5 o'clock) and clot (2 o'clock). IVUS = intravascular ultrasound; OCT = optical coherence tomography; PCI = percutaneous coronary intervention.
