This randomized controlled trial compared intravascular ultrasound (IVUS)-guided planned rotational atherectomy (RA) to cutting balloons (CB) in patients with grade III coronary calcified lesions (CCL). Among 80 patients, the strategy success rate was significantly higher with RA at 95% compared to 80% for CB (p = 0.043), indicating better outcomes for RA in this population.
Key findings
- Strategy success rate was 95% for RA versus 80% for CB (p = 0.043).
- Stent expansion indices were significantly better in the RA group (p <0.05).
- Procedural expenses and contrast amounts were higher in the RA group (p <0.05).
- No significant differences in procedural duration or 30-day MACE were observed (p >0.05).
Why it matters
The findings suggest that IVUS-guided planned RA may offer superior strategy success and stent expansion for patients with moderate to severe CCL, which could influence treatment decisions in this challenging patient population.
