Five seconds of 50–60 W radio frequency atrial ablations were transmural and safe: an<i>in vitro</i>mechanistic assessment and force-controlled<i>in vivo</i>validation

Abstract

High-power, short-duration atrial ablation was as safe and effective as the conventional ablation. Compared with the conventional 40 W/30 s setting, 50 and 60 W ablation for 5 s achieved transmurality and had fewer complications.
