Ablation of accessory pathways in different anatomic locations using focal pulsed field ablation
Authors' conclusion
Focal PFA for AP shows promising results in terms of efficacy and safety.
Study context
- Population
- Patients with indication for accessory pathway ablation (WPW syndrome / atrioventricular reentrant tachycardia), incl. pediatric3 pediatric
- Participants
- 14 patients
- Outcome
- Efficiency (termination of AP conduction) and long-term outcome of AP ablation
Methodological detailsAP locations: 3 right free wall, 3 posteroseptal, 8 left-sided, Follow-up 1-3 months after ablation; additional check-up at 6 and 12 months
- AP locations: 3 right free wall, 3 posteroseptal, 8 left-sided
