      Stent collapse after guide extension catheter collision. Signature procedural finding by optical coherence tomography
      Excessive deformation of stents can lead to strut fracture and subsequent stent collapse. Procedural damages to the stent are rarely visible by angiography during implantation but may be detected by OCT. Here we present a case with a subtle but signature finding by OCT indicative of stent fracture.

      OCT for bifurcation stenting: what have we learned?
      Treatment of bifurcation lesions by percutaneous coronary intervention (PCI) shows major variation in complexity. Intravascular optical coherence tomography (OCT) provides high-resolution images of the pathoanatomy, thrombus, wires and stent positions during the procedure. This information may prove crucial in optimising PCI results and clinical outcomes after complex bifurcation treatment. Mounting evidence confirms the feasibility of OCT in bifurcations, and specific steps where OCT may be advantageous in guiding bifurcation PCI ...
