Overview

Observational study finds local captures in pulmonary veins significantly improve long-term success of radiofrequency ablation in nonparoxysmal atrial fibrillation patients.

Key Points

  • Patients with local captures showed a 77.7% rate of maintained sinus rhythm, compared to 58.9% without.
  • The presence of local captures significantly improved the long-term outcomes of radiofrequency ablation in patients with atrial fibrillation.
  • Analysis indicated that local captures serve as a reliable prognostic predictor (odds ratio 2.439).
  • Follow-up lasted a median of 800 days, with 68.2% achieving overall treatment success, demonstrating substantial efficacy.
