TCT-235 Effect of Additional Lower-speed Rotational Atherectomy on Acute Lumen Gain in vivo and in vitro: Evaluation using OFDI

Abstract

BACKGROUND The association between the platform speed and acute lumen gain remains unknown. The purpose of this study is to evaluate the effect of additional lower-speed rotational atherectomy (RA) following conventional high-speed RA on acute lumen gain using sequential optical frequency domain imaging (OFDI) in vitro and in vivo.
