ST-elevation myocardial infarction caused by very late stent thrombosis due to drug-eluting stent fracture

Although the incidence of coronary stent fracture(SF) is relatively rare,the increasing amount of patients undergoing percutaneous coronary intervention(PCI) indicates more cases of SF.The incidence of sirolimus-eluting stent(SES) fracture is reported in 0.89%to 4.4%of patients at 6 to 12 months follow-up angiography post-PCI.Recently,SF has been recognized as a complication that may result in thrombosis,perforation,restenosis,and migration of the stent resulting in morbidity and mortality.Here we describe a rare case presented with ST-elevation myocardial infarction(STEMI),which was caused by very late stent thrombosis due to SES fracture,in order to help the physicians ensure rapid recognition and treatment of this urgent situation.
