The medical team decided to use the Rotablator System. A 1.75 mm burr was passed through the lesion without difficulty over the RotaWire™ Floppy Guide Wire.
- Following the use of the Rotablator System, the lesion was post dilated with a 4.0 mm × 20 mm PTCA balloon catheter
- The use of the Rotablator System facilitated the delivery and expansion of a 4.0 mm × 9.0 mm stent with good angiographic appearance
The Rotablator System served as a facilitator of lesion compliance and ultimately, stent delivery and expansion.
This case illustrates the ability of the Rotablator System to modify calcified atherosclerotic plaque in order to facilitate optimal stent delivery and expansion. Angiographic assessment did not uncover the calcified nature of the lesion.
After multiple balloon dilatation attempts with non-compliant balloons, the level and extent of calcification was made apparent. Although the 1.75 mm burr did not increase the lumen size, it did allow for subsequent expansion of the lesion by means of a PTCA balloon catheter and stent.
