MECHANISM OF ACTION OF ORBITAL ATHERECTOMY IN SEVERELY CALCIFIED CORONARY ARTERIES: INSIGHTS FROM A CADAVERIC PERFUSION MODEL

Orbital atherectomy (OA) is indicated for facilitating stent delivery in patients by reducing coronary plaque, but complete understanding of the therapeutic mechanism has not been established. We performed a mechanistic study using a cadaveric heart perfusion model to investigate the impact of OA on
