Overview

Systematic review compares efficacy and safety of cryoballoon and radiofrequency ablation for persistent atrial fibrillation, suggesting similar outcomes with significant time savings for cryoballoon.

Key Points

  • Cryoballoon and radiofrequency ablation show similar rates of atrial tachyarrhythmia recurrence among patients with persistent atrial fibrillation.
  • The average operative time is significantly shorter for cryoballoon ablation, reducing by about 45 minutes compared to radiofrequency ablation.
  • Incidences of complications are similar, but the risk of phrenic nerve palsy is notably higher with cryoballoon ablation.
  • Both treatment methods are effective alternatives for persistent atrial fibrillation, offering nearly equal safety profiles.
