Inclusion criteria

Inclusion criteria: Patients treated for severe calcified lesions at the Department of Cardiology, Iwate Medical University Hospital, where imaging evaluation was performed using both (1) OCT (or OFDI) and (2) IVUS from Terumo or Boston Scientific. Severe calcified lesions were defined as those requiring treatment with orbital atherectomy (OA), rotational atherectomy (RA), or intravascular lithotripsy (IVL).

Exclusion criteria

Exclusion criteria: Patients who was less than 18 years old.

Design outcomes
