Conclusions
AF ablation can be performed safely using HPSD strategy with very low
complication rates, including low rates of esophageal complications.
HPSD ablation has the potential to shorten procedural and total RF times
and create more localized and durable lesions. The optimal power and
duration of energy delivery has yet to be determined. Large clinical
trials are needed to study long term efficacy and safety of novel
ablation catheters for very short duration HPSD ablation and to
delineate optimal power settings.
