  Figure 1 (A) Coronary angiography shows intraluminal haziness (arrow) at the mid portion of the previous right coronary artery stent without significant in-stent restenosis. (B) Magnified fluoroscopic images showed suspicious complete separation with displacement of the previous drug-eluting stent overlapping site. (a-d) show each site of axial optical coherence images. (C) Longitudinal optical coherence tomographic images showed multiple stent fractures with 4 gaps. (D) 3D reconstructed stent strut images clearly demonstrated multiple stent fracture with 4 gaps (arrows). (E) 3D reconstructed images showed that the guide-wire was clearly inside the whole fractured stents. (F) After 4.0×18-mm Onyx (Medtronic, Minneapolis, MN, USA) implantation, the final angiogram revealed good distal flow without any residual stenosis or dissection. 3D = 3-dimensional.
