Summary
High-power short-duration (HPSD) radiofrequency ablation improves atrial fibrillation (AF) treatment by increasing pulmonary vein isolation success and reducing reconnection. HPSD offers better long-term AF and atrial tachycardia freedom with similar safety and shorter procedure times compared to conventional settings.
Area of Science:
- Cardiology
- Electrophysiology
- Medical Devices
Background:
- Atrial fibrillation (AF) treatment outcomes can be improved with advanced radiofrequency ablation (RFA) techniques.
- High-power short-duration (HPSD) RFA is a newer approach aiming to enhance efficacy and safety in AF ablation.
Purpose of the Study:
- To compare the efficacy, safety, and effectiveness of HPSD versus conventional RFA settings for AF treatment.
- To evaluate key endpoints including pulmonary vein isolation (PVI) success, reconnection rates, freedom from arrhythmia, and procedural complications.
Main Methods:
- A systematic literature search was conducted across PubMed, Embase, and Cochrane Library.
- Included studies compared HPSD RFA with conventional RFA in AF patients; excluded studies with non-pulmonary vein targets.
- Data were pooled using a random-effect model to analyze efficacy, safety, and effectiveness endpoints.
Main Results:
- HPSD demonstrated a higher first-pass PVI rate (RR=1.10) and lower acute PV reconnection rate (RR=0.56).
- At 12 months post-ablation, HPSD showed significantly higher freedom from AF (RR=1.17) and atrial tachycardia (AT) (RR=1.11).
- Procedural times (total, PVI, RF) were significantly shorter with HPSD, while esophagus injury and major complication rates were similar between groups.
Conclusions:
- HPSD radiofrequency ablation is more effective and efficacious for treating atrial fibrillation compared to conventional settings.
- The HPSD setting offers improved procedural efficiency with comparable safety outcomes.
- HPSD represents a promising advancement in radiofrequency ablation for atrial fibrillation management.
