COMPLIANCE 360º

Compliance360

A prospective, randomized, multi-center study that compared the acute and long-term results of Orbital Atherectomy System (OAS) + percutaneous transluminal angioplasty (PTA) versus PTA alone in calcified above-the-knee (ATK) lesions.

Key Takeaways

  • Lower mean maximum balloon inflation pressure in OAS+PTA arm
  • Lower adjunctive stent rate in OAS+PTA arm
  • OAS demonstrated reduced stenting with durable results out to 12 months versus PTA alone

Study Design

  • 50 patients enrolled at 9 U.S. sites
  • Patients randomized to either OAS+PTA (25 pts) or PTA alone (25 pts) and followed for 12 months
