Rotablation Of Calcified Vessels

• Perform an angiogram to locate the sites of calcification in the arteries – they appear as shadows or “ghost-like” stenoses.
• IVUS or OCT transducer wires can be inserted along the guidewire to get a better perspective of the occlusions.
• Remove the transducer wire and insert the wire with the ablation/ rotablator device into the artery and navigate it to the sight of stenosis. 
• When the rotablator is properly positioned in the vessel, run the device along the site of the stenosis.
• Remove the device and inject contrast media into the introducer sheath and guide catheter to get another angiographic image of the arteries to make sure the vessels are adequately opened.
• An FFR transducer can also be used to ensure the blood flow of the artery is appropriate.
