Abstract Introduction High-power short-duration (HPSD) ablation has emerged as a promising alternative to conventional power delivery (CPD) for pulmonary vein isolation (PVI) among patients with atrial fibrillation (AF). However, its efficacy, procedural efficiency, and safety profile remain uncertain. Methods PubMed, Embase, Cochrane Library and ClinicalTrials.Gov databases were systematically searched for randomized controlled trials (RCTs) comparing HPSD with CPD ablation for PVI in patients with AF. Random-effects models were used to pool hazard ratios (HR) and risk ratios (RR) with 95% confidence intervals (CI). Results Seven RCTs with 1,006 patients (514 HPSD, 489 CPD) were included. No significant differences were found in freedom from arrhythmia during the follow-up period (HR 0.77; 95% CI 0.41–1.45; p=0.424). AF recurrence did not differ (RR 0.94; 95% CI 0.65–1.36; p=0.733) between groups. HPSD had a significantly shorter procedural (MD -22.61 min; 95% CI -33.18, -12.04; p<0.001) and RF ablation (MD -15.70 min; 95% CI -20.86, -10.55; p<0.001) times, with comparable fluoroscopy time (MD 0 min; 95% CI -0.44, 0.45; p=0.99) between groups. Conclusion In patients with AF undergoing PVI, HPSD did not increase freedom from arrhythmia as compared with CPD ablation, however it was associated with shorter procedure and RF ablation times. These findings suggest that HPSD may be a more efficient approach without compromising clinical outcomes.
