More Fractures

The More Severe the Calcium, the Greater the Incidence of Fracture

Improved Compliance

Improved Vessel Compliance Enables Similar Stent Expansion Across AllLesions, Despite Calcium Severity

A. Calcified, stenotic lesion
Treat with IVL
B. Large luminal gain with multiple calcium fractures (white arrows)
Deploy Stent
C. Stent expansion showing compliance and increased fracture size with additional increase in acute gain
