Neoatherosclerosis in Very Late Stenosis of Bare Metal Stent by Optical Coherence Tomography

Bare metal stents (BMS) continue to be widely used in patients with coronary artery disease undergoing percutaneous revascularization. Progressive luminal renarrowing has been reported late after BMS implantation resulting in a significant rate of stent failure events. We present a case of very late BMS failure due to in-stent restenosis where optical coherence tomography (OCT) was used to demonstrate neoatherosclerosis as the underlying mechanism. We provide a brief review of neoatherosclerosis and showcase salient features on OCT evaluation.
