PRELUDE Study Summary

The PRELUDE Study (Prospective Study for the treatment of Atherosclerotic Lesions in the Superficial Femoral Artery and/or Popliteal Artery Using the Serranator Device) is a single-arm, prospective, multicenter feasibility study enrolling up to 30 subjects with superficial femoral or popliteal lesions.

PRELUDE Conclusions

  • Serranator Alto is safe and effective in treating critical femoro-popliteal lesions
  • 100% technical success
  • Confirmation of serration effect by OCT and IVUS
  • Acute results show that Serranator Alto can achieve low residual stenosis
  • Serranator Alto showed effectiveness in moderate to severe calcification
  • Majority of subjects successfully treated at low pressure inflation
  • Final study results by the close of 2017

The reference vessel diameter was 4.19 mm; lesion length was 54.28 mm; percent stenosis was 100% (A). A 5 mm X 80 mm Serranator® Alto was inflated to 6 atm (B). After treatment, residual stenosis was 20.23% (C).

The reference vessel diameter was 6.12 mm; lesion length was 30.04 mm; percent stenosis was 94.59% (A). A 6 mm X 40 mm Serranator® Alto was inflated to 11 atm (B). After treatment, residual stenosis was 24.07% (C).

The reference vessel diameter was 5.15 mm; lesion length was 28.42 mm; percent stenosis was 77.02% (A). A 5 mm X 40 mm Serranator® Alto was inflated to 6 atm (B). After treatment, residual stenosis was 12.84% (C).

PRELUDE Study OCT & IVUS Images Show Serrations

IVUS*: “Controlled modification of severe intimal calcification by the Serranator® Alto.  Note the controlled acute luminal gain of the impacted calcified intimal layer.”

– J. Mustapha, MD

OCT*: “Shows clear evidence of serration caused by the Serranator® Alto device.”

– A. Holden, MBChB, FRANZCR, EBIR
