Conclusions
In this initial study, we demonstrate that endocardial ablation can be
performed safely and effectively using a novel family of bipolar,
single-shot, spiral PFA/mapping catheters. Furthermore, this PFA system
allows for creation of wide, transmural lesions within the atria and
durable PV isolation without significant skeletal muscle
twitch/activation, thromboembolism, collateral injury to the PN or
bronchi or long-term abnormalities in the adjacent esophagus when
manually deviated to render contiguous with the site of the energy
source.
