Immediate stent fracture after everolimus-eluting stent implantation: a case report

A 60-year-old man presented with exertional chest pain and was hospitalized on a diagnosis of unstable angina. Coronary angiography revealed left main true bifurcation lesions and percutaneous coronary intervention (PCI) was conducted using the culotte-stenting technique. Post-dilatational angiography revealed an irregular protrusion of the stent strut in mid left anterior descending (LAD) coronary artery. Intravascular ultrasound (IVUS) showed a discontinuation of the middle stent strut with calcified nodules. An additional everolimus-eluting stent (EES) was placed across the discontinued lesions. Post-procedural IVUS revealed good expansion of the stents and final angiography showed optimal angiographic results with thromboly sis in myocardial infarction (TIMI) 3 flow. The patient was discharged the next day after the operation and maintained asymptomatic for chest pain at the 6-month follow-up point.
