“…Collateral damage of adjacent tissue is a limitation of thermal energy sources for catheter ablation of arrhythmias, leading to rare (<0.05%) life‐threatening complications such as atrioesophageal fistula 19 . New ablation strategies, such as high‐power short‐duration (HPSD) RF ablation cause more local resistive heating and local atrial tissue destruction without conductive heating of more distant tissue that might cause less distant collateral damage 20 . Studies show markedly low esophageal injury after HPSD ablation 21–23 …”

“…High power (45–50 W) short duration (5–10 s) ablation (in power‐controlled mode), which produces wider and shallower lesions compared to conventional radiofrequency application approaches, appears to have an overall excellent safety profile 50 . Given the LAPW is a thin walled structure, high power short duration ablation may be particularly well suited for effecting shallow but transmural lesions that reduce the risk for esophageal damage 51 …”

“…Atrial arrhythmia recurred less frequently in the HPSD group, probably because HPSD ablation produces more resistive heating, leading to durable lesions (6). In animal studies, lesion sets formed with 50 W-60 W ablations for 5 seconds at 10 g CF were transmural (38).…”

“…Conversely, high-power short-duration (HPSD) ablation produces a much larger area of resistive heating to create the transmural lesion and a smaller area of conductive heating to alleviate complications associated with posterior wall isolation (PWI) (6). Initial results from HPSD ablation include shorter procedure and ablation times and equivalent safety and efficacy compared with conventional ablation, which has popularized the HPSD approach (7).…”
