A 64-year-old female with chronic kidney disease was scheduled to undergo stenting of a severely calcified lesion in the left anterior descending coronary artery following “preparation” of the lesion by orbital atherectomy performed with the Diamondback 360® Coronary Orbital Atherectomy System (OAS), 1.25 mm Classic Crown (Cardiovascular Systems, Inc., St. Paul, MN, USA) (Figure 1A) (pre- and post-OAS angiography: Figure 1B-1C and Figure 1B’-1C’, respectively). The first run was performed at 80,000 rpm for 25 s followed by the second run at 120,000 rpm for 25 s. A 2.75×38 mm everolimus-eluting stent (XIENCE; Abbott Vascular, Santa Clara, CA, USA) was successfully implanted. Optical coherence ...
