Key result
High-power short-duration AF ablation shortens procedure times vs conventional low-power ablation with similar complication rates.
Why the study?
The optimal levels of power and duration for RF catheter ablation in AF to achieve successful ablation while avoiding complications remain unknown.
Does high-power short-duration radiofrequency ablation improve procedural efficiency and outcomes compared to low-power long-duration ablation in patients with atrial fibrillation?

High-power short-duration radiofrequency ablation is a promising alternative to conventional ablation for atrial fibrillation, offering shorter procedural times and potentially more durable lesions, though large clinical trials are needed to determine optimal settings.
May shorten AF ablation times without added risk; leaves open optimal parameters and long-term outcomes pending randomized trials.
Radiofrequency (RF) catheter ablation is an established method of treating patients with atrial fibrillation (AF). However, the optimal levels of power and duration required to achieve a successful ablation while avoiding complications are unknown. High-power short-duration (HPSD) ablation for the treatment of AF is already emerging as an alternative to conventional low-power long-duration (LPLD) procedures. Potential advantages of HPSD ablation include efficacy, safety and reduction in procedural and RF time, through the ability to create durable and geometrically favourable lesions. This article describes the development of HPSD ablation and reviews its place in the treatment landscape for AF.

Κόλλιας et al. (2022) conducted a review in Atrial fibrillation. High-power short-duration (HPSD) radiofrequency ablation vs. Low-power long-duration (LPLD) radiofrequency ablation was evaluated. High-power short-duration radiofrequency ablation for atrial fibrillation offers shorter procedural and radiofrequency times with similar complication rates compared to conventional low-power ablation.
