Structured PICO
Do P-wave parameter changes differ after PFA, Cryo, and RF ablation for paroxysmal atrial fibrillation, and do they predict AF recurrence?
P
Population
Patients with paroxysmal atrial fibrillation
I
Intervention
Pulsed-field ablation (PFA), cryoballoon ablation (Cryo), or radiofrequency ablation (RF)
C
Comparator
Comparison between PFA, Cryo, and RF ablation modalities
O
Outcome
Acute ECG changes (P-wave parameters) and atrial fibrillation recurrencesurrogate
Post-procedural P-wave duration is a strong predictor of AF recurrence after ablation for paroxysmal AF, regardless of the ablation modality used.
Abstract
PFA, RF, and Cryo produce similar acute ECG changes. Post-procedural PWD was the strongest predictor of AF recurrence, independent of atrial size and AAD use.
