Predictors of AAs recurrence after the initial CA
In univariable analysis, longer AF duration, EGM-guide ablation and AF at the beginning of the index CA procedure were identified as predictors of AAs recurrence after the index ablation. Of note, incomplete line block and non-termination during EGM-guide ablation did predict AAs recurrence. In multivariable analysis, longer AF duration and EGM-guided ablation remained as independent predictors of AAs recurrence (OR: 1.01, 95%CI: 1.00-1.03, p=0.015, OR: 2.45, 95%CI: 1.47-4.09, p=0.0007, respectively, Table 3 ).
