Introduction: An entrapped guidewire is a rare complication of percutaneous coronary intervention (PCI). 

Case report: We herein present the case of a 73-year-old female patient diagnosed with myocardial infarction. While performing PCI, all attempts to pull out entrapped guidewire caused longitudinal, accordion-like deformation of the stent implanted in OM. By advancing a small over-the-wire (OTW) balloon to the entangled segment of the wire, a narrow space between the deformed stent and vessel wall was created after balloon inflation, causing the wire to untangle. Re-coronarography was performed 10 days after the initial procedure. 

Conclusion: Using optical coherence tomography during complicated PCI, could be of great importance for the evaluation of stent expansion and apposition.
