A Novel Rotablator Technique (Low-Speed following High-Speed Rotational Atherectomy) Can Achieve Larger Lumen Gain: Evaluation Using Optimal Frequency Domain Imaging

<p><i>Study Flowchart of Human Studies.</i> 30 lesions in patients who underwent rotational atherectomy (RA) with 1.5 mm burr from June 2013 to January 2017. 15 lesions were ablated at 190,000 rpm, defined as high-speed RA (HSRA), and 15 lesions were ablated at 190,000 rpm followed by 110,000 rpm, defined as additional low-speed RA (LSRA) following HSRA. Post-RA minimum lumen diameter (MLD) and minimum lumen (MLA) were measured immediately afterwards by optical frequency domain imaging (OFDI).</p>
