The use of intravascular ultrasound (IVUS) to guide stent implantation in bifurcation lesions, especially for the detection of procedure-related complications, has decreased the rates of major clinical outcomes. We report a case of a patient undergoing bifurcation intervention, where the guidewire inadvertently was passed behind the proximal stent struts, deforming the stent edge. This complication was suspected at the angiography and was confirmed by IVUS. IVUS was crucial for the diagnosis, to confirm the correct repositioning of the guidewire, and to assess the optimal expansion and complete apposition of stent struts, thus preventing a possible early thrombotic event and ensuring a good long-term outcome.
