Orbital Treatment in a High Volume Clinical Practice
Single-Center Physician Initiated Study Confirms Modifying Non-Compliant Plaque with Orbital Atherectomy Delivers Durable Long-Term Results
Study Overview
Patient with PAD underwent primary intervention with Predator 360 PAD System, followed by low-pressure balloon inflation pressures, if necessary.

Key Findings
-
Durable long-term results can be achieved out to 12-months with orbital technology
1, 2 - 10.9% reintervention rates at one year.
Conclusions
-
The use of orbital technology modifies lesion compliance in resistant plaques.
- Demonstrated by successful index procedure outcomes that utilized only low-pressure and short duration post-orbital balloon inflations.
- Bail-out stenting was eliminated in this challenging patient population.
- Use of orbital technology resulted in durable long-term results as demonstrated by low reintervention rate at 12 months.
