Freezing heart tissue to stop AFib: new device under study
NCT ID NCT06170606
First seen Jun 24, 2026 · Last updated Jul 01, 2026 · Updated 4 times
Summary
This study tests a device that freezes small areas of heart tissue to treat paroxysmal atrial fibrillation (AFib), a condition where the heart beats irregularly. About 200 people with AFib that hasn't responded to medication will receive the procedure. Researchers will track safety and effectiveness for 12 months, looking for serious side effects and whether the heart stays in normal rhythm.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Cardiac Cryoablation System (device that freezes heart tissue to stop abnormal signals)
What this could lead to
If successful, this could offer a safe, effective way to control paroxysmal atrial fibrillation without needing lifelong medication.
What could go wrong
This is a single-arm study with no comparison group, so results may be less definitive. Risks include serious complications like stroke, heart damage, or blood clots.
