A calcified neointima--"stent" within a stent.
De novo atherosclerosis arising within a coronary stent is rare and generally occurs many years after stent deployment. We describe a case of restenosis in a patient presenting with angina 8 years after original stent deployment. Intravascular ultrasound greyscale imaging and virtual histology demonstrated that this "neointima" was calcified.
