Feasibility study on atrial fibrillation ablation with pulsed field ablation and concomitant occlusion of the left atrial appendage
Authors' conclusion
Simultaneous PFA-based AF ablation and LAAO in carefully selected patients is feasible and safe and can be executed within a short overall procedure duration.
Study context
- Population
- Patients qualifying for both atrial fibrillation (AF) ablation and left atrial appendage occlusion (LAAO), excluding complex anatomy2 excluded (complex LAA anatomy)
- Participants
- 10 / 207 / 61
- Comparison
- Combined pulsed field ablation (PFA)-based AF ablation plus LAAO vs individual AF ablation or LAAO alone
- Combined proceduren = 10
- AF ablationn = 207reference
- LAAOn = 61reference
- Outcome
- Procedure duration and fluoroscopy time
Methodological detailssame operators, comparison with individual procedures
- Same operators
- Comparison with individual procedures
