Accordion Stent Deformation upon Retrieval of a Side-Branch Protective Guidewire.
In this case we herein report a dangerous complication from primary percutaneous coronary intervention, where an unnoticed loop of the guidewire was inadvertently made around the stent during provisional stenting. Since the guidewire and the stent were entangled, efforts to retrieve the guidewire only exacerbated the problem by compressing the stent like an accordion. We review those factors that may have influenced stent compression in our case, as well as possible ways to avoid it from occurring in the future.
