High power, shorter duration (HPSD) ablation strategies have been advocated to increase efficacy and minimize posterior wall deep tissue thermal injury during atrial fibrillation (AF) ablation. ⋯ Long-term freedom from AF rates were not significantly different between both approaches. An HPSD ablation strategy compared with an LPLD approach was associated with an increased risk of AFL and need for repeat ablation but with lowered procedure times.
