Why the study?
Does high-power short-duration radiofrequency ablation (50-80 W for 5 s) achieve similar lesion depth with fewer complications compared to conventional ablation (40 W for 30 s) in an ovine model?
Population
In vitro models and in vivo models (10 Ovine, 72 lesions on the non-trabeculated part of right atrium)
Comparison
High-power short-duration radiofrequency ablation vs Conventional radiofrequency ablation
Design
Preclinical

Comparable lesion depths with fewer steam pops in ovine model support preclinical validation; leaves open translation to human AF ablation.
Does high-power short-duration radiofrequency ablation (50-80 W for 5 s) achieve similar lesion depth with fewer complications compared to conventional ablation (40 W for 30 s) in an ovine model?
High-power short-duration atrial ablation (50-60 W for 5 seconds) achieves transmurality comparable to conventional ablation with fewer complications in an ovine model.
