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.
