Although late stent thrombosis is not uncommon with the use of drug-eluting stents, it is unusual with the use of bare-metal stents (BMS) because stent endothelialization is considered to be completed 4 weeks after the intervention.1) A 64 year-old male had undergone percutaneous coronary intervention (PCI) for a proximal left anterior descending (LAD) artery lesion with a BMS and excellent angiographic results were obtained. Two hundred mg of ticlopidine was prescribed for one month and 100 mg of aspirin daily was continued. One year after stent implantation, coronary angiography (CAG) showed no restenosis. Ten years and 7 months after stent implantation, he suffered an acute myocardial infarction due to stent thrombosis. Intra-coronary aspiration thrombectomy was successful. To the best of our knowledge, the longest delayed case of BMS thrombosis is 5 years after stent implantation.2) Our report demonstrated evidence of the latest reported case of stent thrombosis with the use of a BMS.
