Retrospective study assesses wire bias pattern's relationship with coronary artery injury during atherectomy for calcified nodules, suggesting its role as a predictor.
Background: Calcified nodules (CN) are a challenging coronary lesion subset often treated with orbital atherectomy (OA), which, although effective, carries a risk of coronary artery injury (CAI), including hematoma and perforation. In this study we assessed the relationship between intravascular ultrasound (IVUS) findings, particularly the wire bias pattern, and CAI during OA for CN.
