Key Result

Combined wide area circumferential ablation (WACA) and cardioneuroablation (CNA) provide lasting relief of vagally mediated swallowing syncope in AF patients.

Key Points

  • The study aims to evaluate the effectiveness of combined wide area circumferential ablation and cardioneuroablation in treating swallowing syncope associated with atrial fibrillation.
  • Combination of wide area circumferential ablation and cardioneuroablation performed on patients.
  • Focus on individuals experiencing swallowing syncope due to atrial fibrillation.
  • Assessment of relief duration and symptom recurrence.
  • Patients experienced durable relief from swallowing syncope.
  • Significant reduction in vagally mediated episodes was reported.
