Endovascular treatment of severely calcified coronary artery lesions is associated with lower procedural success and higher complication rates compared to non-calcified lesions. Rotational atherectomy (RA) and orbital atherectomy (OA) are different therapy approaches, with the latter demonstrating potential for decreased device utilization and reintervention rates. The objective was to explore the budget impact for the Japanese healthcare system of adopting OA compared to RA.
