Key result
Successful ablation of non-pulmonary vein foci in paroxysmal atrial fibrillation yielded an 8.8% recurrence rate, significantly lower than the 68.0% rate with incomplete ablation (P<0.0001).

Targeting non-PV foci may improve PAF ablation outcomes; leaves open need for randomized confirmation.

Does successful ablation of non-pulmonary vein foci improve atrial fibrillation recurrence rates in patients undergoing paroxysmal atrial fibrillation ablation?
Absolute Event Rate: 8.8% vs 68%
p-value: p=<0.0001
Successful detection and elimination of non-pulmonary vein foci during paroxysmal atrial fibrillation ablation yields recurrence rates comparable to patients without non-PV foci.
Hayashi et al. (2015) conducted a cohort in Paroxysmal atrial fibrillation (PAF) (n=304). Successful ablation of non-pulmonary vein foci vs. Incomplete ablation of non-pulmonary vein foci was evaluated on Atrial fibrillation recurrence (p=<0.0001). Successful ablation of non-pulmonary vein foci in paroxysmal atrial fibrillation yielded an 8.8% recurrence rate, significantly lower than the 68.0% rate with incomplete ablation (P<0.0001).
