Calcified neoatherosclerosis represents a particularly challenging scenario in patients with in-stent restenosis (ISR), frequently associated with worse angiographic and optical coherence tomography (OCT) results compared with other patients with typical ISR. Intravascular lithotripsy (IVL) has emerged as a safe and effective technology to circumferentially modify calcium in heavily calcified coronary lesions. Preliminary data also suggest its usefulness in calcified neoatheroscerosis. This case report aims to describe a novel fracture pattern after IVL identified by OCT (the "rock strata peeling pattern") in patients presenting with ISR due to calcified neoatherosclerosis.
Keywords: coronary artery disease; in-stent restenosis; intravascular lithotripsy; percutaneous coronary intervention.
