Background: Coronary artery bypass grafting (CABG) is a cornerstone treatment for coronary artery disease, with the use of saphenous vein grafts (SVGs) being prevalent. However, SVGs are susceptible to high failure rates due to graft inflammation, intimal hyperplasia, and atherosclerosis, leading to a substantial number of patients requiring revascularization. Percutaneous coronary intervention (PCI) of SVGs poses unique challenges, including increased risk of distal embolization and perforation due to the grafts' structure and atherosclerotic nature.

Background: Neoatherosclerosis, a prominent contributor to in-stent restenosis (ISR), persists as a formidable challenge during percutaneous coronary intervention. Excimer laser coronary atherectomy (ELCA) and embolic protection devices may help reduce coronary flow disturbance from procedure-related distal embolization.

Case Summary: A 71-year-old man experienced in-stent neoatherosclerosis rupture-related non-ST segment elevation myocardial infarction.
