Article Synopsis
- Pulsed-field ablation (PFA) is a new technique for treating atrial fibrillation (AF) that targets heart tissue more selectively than traditional thermal methods like radiofrequency and cryoablation.
- A systematic review of 17 studies with 2,255 patients found that PFA significantly lowers AF recurrence, procedure time, heart rate changes, and risks of certain complications like phrenic nerve palsy and esophageal lesions.
- However, PFA is also linked to a higher risk of pericardial tamponade, indicating it has both benefits and potential risks compared to thermal ablation.
Background: Persistent atrial fibrillation (AF) is associated with high recurrence rates of AF and atypical atrial flutters or tachycardia (AFT) postablation. Laser balloon (LB) ablation of the pulmonary vein (PV) ostia has similar efficacy as radiofrequency wide area circumferential ablation (RF-WACA); however, an approach of LB wide area circumferential ablation (LB-WACA) may further improve success rates.
Objective: To evaluate freedom from atrial tachyarrhythmia (AFT/AF) recurrence postablation using RF-WACA versus LB-WACA in persistent AF patients.
