Learning points

• Lesions selection for Rotational atherectomy.
• How to prepare  and use the device.
• Guiding catheter, guidewire  and Burr size selection.
• How to perform multilevel plaque modification.
• Guiding catheter extension to improve support and stent delivery.
• IVUS assessment before and after stenting.

Step-by-Step Procedure

• Arterial Femoral access 7F, Temporary pace-maker insertion and RCA catheterization with JR4 7F Guiding catheter.
• Crossing the lesion using Whisper LS coronary PCI guidewire.
• Exchange the Coronary guidewire with Rotawire Extra support guidewire using a Finecross microcatheter.
• Rotational atherectomy runs from proximal RCA to the distal bifurcation with 1.5mm Burr.
• IVUS assessment showing optimal plaque modification.
• Predilatation with 3.0x20mm balloon and Rotawire exchange to BMW 0.014 guidewire.
• Stenting of the distal bifurcation with 4.5x18mm Onyx Drug Eluting Stent using Guideliner catheter extension.
• Stenting of the distal PL with 3.5x12mm Onyx stent for dissection.
• Stenting of the Mid and Proximal RCA .
• IVUS control of the final result.
