We reviewed with interest the article by Nery et al. describing catheter ablation
of low-voltage areas in the treatment of persistent atrial fibrillation.
1
The authors should be commended on this study, particularly given that the previously
reported success rates for catheter ablation of persistent atrial fibrillation are
43% following a single procedure using any ablation technique.
2
In this study, the authors found that by targeting low-voltage areas in addition
to performing a pulmonary vein isolation, there was an increased freedom from atrial
tachycardia and atrial fibrillation from 58% to 72% at 18 months with no additional
complications noted.To read this article in full you will need to make a payment

- PreviewSeveral approaches have been proposed to address the challenge of catheter ablation of persistent atrial fibrillation (AF). However, the optimal ablation strategy is unknown. We sought to evaluate the efficacy of pulmonary vein isolation (PVI) plus low-voltage area (LVA) ablation using contemporary high-density mapping to identify LVA in patients with persistent AF.

- PreviewWe thank Hong et al. for their interest in our work and their comments. In response to their specific points, a bipolar voltage cutoff < 0.5 mV was used to detect low-voltage areas using high-density multielectrode catheters with 1-mm electrodes and 2-mm electrode spacing. The majority (8 of 10) of published studies in the field of catheter ablation for persistent atrial fibrillation have used the same cutoff. We acknowledge the need for histologic correlation; however, this approach is based on best currently available data.
