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.
