Abstract:
We describe an uncommon and potentially life-threatening complication during stent assessment by optical coherence tomography (OCT) with entrapment and complete stent removal. Possible mechanisms for OCT-catheter entrapment include malapposed stent struts, catheter deformation, and loss of guidewire position. In this case, the OCT catheter was advanced over the guidewire, which was probably passed through a proximal malapposed stent strut. Tips to avoid potential complications during OCT performance are provided.
