- The study evaluates the prognostic impact of early recurrences after pulsed field ablation (PFA) for atrial fibrillation (AF).
- Early recurrences within 30-, 60-, and 90-days post-ablation are strongly associated with late recurrences beyond 90 days.
- Findings suggest that early recurrences after PFA are predictive of long-term arrhythmia recurrence, challenging the conventional blanking interval concept.
- The study included 1162 patients across multiple centers within the Mayo Clinic health system.
- AF-free survival at 1 year was estimated at 70%, with early recurrences significantly linked to higher AF burden or need for repeat ablation.
