Conclusion:
LA PWI utilizing a CFS ablation catheter for NPAF patients resulted in a similar incidence of any atrial arrhythmia >30s, but lower incidence of recurrent AT, lower incidence of persistent AT/AF, and lower likelihood of requiring repeat ablation compared to a stepwise linear ablation approach. Our results are consistent with prior literature showing lack of benefit for more extensive ablation strategies for NPAF after a single procedure, and find no evidence that more extensive initial ablation is beneficial for subsequent procedures.
