Bronchial Safety After Pulsed Field Ablation for Paroxysmal Atrial Fibrillation
Authors' conclusion
Pulmonary vein isolation using PFA for paroxysmal atrial fibrillation does not cause thermal lesions in the bronchial system.
Study context
- Population
- Patients undergoing pulmonary vein isolation with pulsed field ablation (PFA) for paroxysmal AF2 series of 30
- Participants
- 30 vs 30
- Exposure
- Straight-tip vs J-tip guide wire during PFA
- Straight-tip guide wiren = 30
- J-tip guide wiren = 30
- Outcome
- Bronchial effects on bronchoscopy
- Follow-up
- 1 day after procedure
