Which ablation method best prevents stroke in atrial fibrillation?
NCT ID NCT06253000
First seen Jun 25, 2026 · Last updated Jul 21, 2026 · Updated 3 times
Summary
This study compares two common procedures—radiofrequency and cryoablation—for treating persistent atrial fibrillation, a heart rhythm disorder that raises stroke risk. Researchers will track 158 adults over 24 months to see which method better prevents strokes, transient ischemic attacks, and death. The goal is to identify the safest and most effective approach for long-term control.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Cryoablation and radiofrequency ablation procedures
- What this could lead to
- If successful, this could help doctors choose the best ablation method to reduce stroke and recurrence in patients with persistent atrial fibrillation.
- What could go wrong
- This is a single-center study with 158 participants, so results may not apply to all patients. Both procedures carry risks like bleeding or heart damage.
