    Optical coherence tomography of late acquired bare metal stent malapposition: Bare metal stent “diverticulosis”

    Figure 1. Coronary angiogram and optical coherence tomographic (OCT) images of the right coronary artery. (A) Initial lesion prior to stent placement. (B) Immediately post stent insertion. (C) At repeat angiography for NSTEMI demonstrating presence of multiple prominent “diverticuli” in the mid-segment of the stent (arrow). (D and E) OCT images demonstrating LASMA with poor neointimal coverage of affected struts and microthrombi formation within the outpouchings (arrows). (F) OCT image demonstrating good neointimal coverage of other segments of the stent. The lower OCT panel shows a longitudinal view of the pullback (proximal segments on right) with representative cross-sectional frames at ...
