An angiogram revealed occlusion in the left circumflex (LCX) artery. Attempts to pass a guidewire through the lesion led to its entrapment and eventual fracture. Several techniques and manoeuvres failed to retrieve the fractured guidewire, which remained lodged in the LCX. An endovascular snare catheter also proved unsuccessful. The fragment was eventually removed using the triple-wire technique, although this caused coronary perforation and dissection. The perforation was identified and stented. A subsequent stent addressed a dissection in the LM/LAD area, likely caused by the coronary snare. These interventions were crucial in stabilising the patient's condition, leading to recovery with a left ventricular ejection fraction of 50% and a viable LCX artery. The patient exhibited an uneventful progression at the 1-year follow-up.\u0000 \u0000 \u0000 \u0000 Coronary guidewire fracture during PCI is a rare event often associated with coronary calcifications.
