Limitations:
Our study has potential limitations. The study is single center and was
non-randomized and therefore bias related to the strategy of ablation
applied for each patient cannot be excluded. Nevertheless, the findings
of the present study are important. A strategy of ablation based solely
on the use of ablation catheter with single trans-septal, ablation
guided by AI based on WACA and additional carina ablation can achieve
high rate of first pass isolation safely and with high long-term success
rate. Randomized, larger studies are needed to confirm the feasibility
of this approach.
