BACKGROUND: Coronary guidewire entrapment is not an uncommon complication of percutaneous coronary intervention, especially in the setting of complex coronary anatomy. Core wire fracture with uncoiling of spring wire represents a catastrophic complication, posing great technical difficulty in percutaneous retrieval.
CASE SUMMARY: The patient was a 50-year-old Asian male with ischaemic cardiomyopathy and severe left ventricular impairment. Coronary angiography showed severe left main and triple-vessel disease. Coronary artery bypass graft was declined due to high surgical risk. Percutaneous coronary intervention was performed under mechanical circulatory support. However, it was complicated with guidewire entrapment and unravelling with deformity of the newly implanted stent in the left anterior descending artery. The complication was successfully bailed out by rotational atherectomy and the novel intravascular ultrasound (IVUS) and enhanced stent visualization (ESV) system guided 'Twist-wire' technique. Complete wire fragments retrieval was achieved with excellent final angiographic and IVUS results immediately after procedure and at 4-month follow-up angiography.
DISCUSSION: This case represents a rare phenomenon of branch point protrusion of stent causing guidewire-stent edge entanglement. A novel 'Twist-wire' technique with IVUS and ESV guidance was highlighted to allow successful retrieval of fluoroscopically invisible uncoiled wire filaments.
