A male who were implanted bare metal stent 11 years ago were admitted for acute coronay syndrome. Optical coherence tomography showed a neointimal disruption and integrated backscatter intravascular ultrasound revealed a lipid pool around the disrupted neointima, suggesting newly formed atherosclerotic neointima developed after bare metal stent implantation. The disruption of atherosclerotic neointima may represent a new potential mechanism of very late stent thrombosis after bare metal stent implantation.
