High-power delivery over a short period of time (HPSD) in RFA is stated to create more efficient lesions. The aim of this study was to compare intraprocedural safety and outcome of HPSD ablation to conventional power settings in patients undergoing PVI for PAF.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods and results<\/jats:title>\n                  <jats:p>We included 197 patients with PAF that were scheduled for PVI. An ablation protocol with 70\u2009W and a duration cut-off of 7\u2009s at the anterior left atrium (LA) and 5\u2009s at the posterior LA (HPSD group; n\u2009=\u200997) was compared to a conventional power protocol with 30\u201340\u2009W for 20\u201340\u2009s (standard group; n\u2009=\u2009100) in terms of periprocedural complications and a 1-year outcome. The HPSD group showed significantly less arrhythmia recurrence during 1-year follow-up with 83.1% of patients free from atrial fibrillation compared to 65.1% in the standard group (P\u2009&amp;lt;\u20090.013). No pericardial tamponade, periprocedural thromboembolic complications, or atrio-oesophageal fistula occurred in either group. Mean radiofrequency time (12.4\u2009\u00b1\u20093.4\u2009min vs. 35.6\u2009\u00b1\u200912.1\u2009min) and procedural time (89.5\u2009\u00b1\u200923.9\u2009min vs. 111.15\u2009\u00b1\u200927.9\u2009min) were significantly shorter in the HPSD group compared to the standard group (both P\u2009&amp;lt;\u20090.001).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>High-power short-duration ablation demonstrated a comparable safety profile to conventional ablation.
