Patients were eligible for enrollment if they had claudication or critical limb ischemia (CLI) and at least moderate calcification as assessed by angiography.

Mean lesion length was 64.7\u00b154.7\u2009mm with moderate to severe calcification in 69.3% of lesions by the Peripheral Academic Research Consortium (PARC) criteria. Adjunctive calcium-modifying technology, defined as scoring or cutting balloon and\/or atherectomy, was used in 22.7% of procedures. The average acute gain at the end of the procedure was 2.0\u00b10.7\u2009mm with a residual stenosis &lt;50% achieved in 99.0% of lesions and a mean residual stenosis of 23.3\u00b112.5%.
