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). R version 4.4.2 was used for statistical analysis. 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 times (MD -15.70 min; 95% CI -20.86, -10.55; p<0.001). No differences were observed in fluoroscopy time and first-pass isolation for right and left pulmonary veins. There was no difference in esophageal lesion rates, pericardial, or neurological complications, but there was a higher incidence of steam pops in HPSD (RR 3.42; 95% CI 1.45–8.09; p=0.005). 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 with a similar safety profile.
