Overview

May support OAC discontinuation after successful ablation; challenges guideline recommendations based on non-randomized data.

Key Points

  • This analysis aims to assess the safety and efficacy of stopping oral anticoagulation therapy after successful catheter ablation in patients with atrial fibrillation.
  • Performed a meta-analysis of randomized controlled trials
  • Included 2,324 patients with successful catheter ablation
  • Calculated pooled effect estimates as risk differences with 95% confidence intervals.
  • Stopping oral anticoagulation did not significantly increase stroke or embolism risks after ablation.
  • Continued anticoagulation was associated with an increased risk of major bleeding (RD 1.0%, 95% CI 0.2%–1.7%).
  • Discontinuation reduces bleeding complications without increasing thromboembolic events.

Discontinuing oral anticoagulation after successful catheter ablation for atrial fibrillation may safely reduce bleeding risks without increasing thromboembolic events, challenging current guidelines.
