Background: Myocardial bridging (MB) is a known congenital anomaly in which a segment of the coronary artery transverses from the epicardium through the myocardium. MB may clinically manifest as recurrent angina, acute coronary syndrome, ventricular dysrhythmia, and even sudden cardiac death. On electrocardiogram (EKG), MB can present with findings consistent with significant ST-segment changes.

The purpose of this retrospective analysis was to gain further knowledge by analyzing the in-hospital and 30-day outcomes of complex PCI patients (including diabetics) treated with coronary orbital atherectomy (OA) at centers without on-site surgical back-up.
Methods/materials: All comers treated with OA at two centers without on-site surgical backup were included.
