Arrhythmias & electrophysiology
Hybrid-Convergent Procedure or Pulsed Field Ablation in Long-Standing Persistent Atrial Fibrillation
Authors' conclusion
Hybrid-convergent and PFA share comparable arrhythmic outcomes in LSPAF, but hybrid-convergent ablation carries higher periprocedural risks.
Study context
- Population
- Consecutive patients with long-standing persistent AF
- Participants
- 93 patients
- Exposure
- Hybrid-convergent radiofrequency (RF) ablation vs pulsed field ablation (PFA) of pulmonary veins (PVs) and left atrial posterior wall (LAPW)
- Hybridn = 49reference
- PFAn = 44
- Outcome
- Any atrial tachyarrhythmia recurrence after the 3-month blanking period
- Follow-up
- 12 months
Methodological detailsconsecutive patients
- Consecutive patients
Main finding
As reported in the abstract
P = 0.680
Observational data: associations, not effects.
Further findings
Step 1 procedure duration
P < 0.01
Predictors of atrial tachyarrhythmias (ATA) recurrence (adjusted)
- Larger left atrial volume and blanking-period recurrences predicted ATA recurrence, regardless of technique
Safety
Major periprocedural complications
P = 0.028
