First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how safe and effective a freezing treatment (cryoablation) is for people with a type of irregular heartbeat called paroxysmal atrial fibrillation (AFib). The treatment uses a device called POLARx to freeze heart tissue and stop the faulty signals causing AFib. 295 patients took part, and researchers tracked any side effects and whether the heartbeat stayed normal for up to a year.
