High-power short duration vs. conventional radiofrequency ablation of atrial fibrillation: a systematic review and meta-analysis
Key result
High-power short-duration radiofrequency ablation was associated with higher freedom from atrial arrhythmia compared with conventional ablation (OR 1.44; 95% CI 1.10-1.90; P=0.009).
Why the study?
The authors sought to compare the effectiveness and safety of high-power short-duration radiofrequency ablation with conventional radiofrequency ablation in patients with atrial fibrillation.
Does high-power short-duration radiofrequency ablation improve freedom from atrial arrhythmia in adult patients undergoing initial catheter ablation for atrial fibrillation?

Cite This Study
Ravi et al. (2020) conducted a meta-analysis in Atrial fibrillation (n=3,718). High-power short-duration (HPSD) radiofrequency ablation vs. Conventional radiofrequency ablation was evaluated on Freedom from atrial arrhythmia (OR 1.44, 95% CI 1.10-1.90, p=0.009). High-power short-duration radiofrequency ablation was associated with higher freedom from atrial arrhythmia compared with conventional ablation (OR 1.44; 95% CI 1.10-1.90; P=0.009).
