Early recurrence post-ablation strongly predicts late failure, but optimal blanking-period management remains undetermined.
ERAA after AF ablation is a strong predictor of late recurrence, but because some episodes resolve spontaneously, the optimal duration of the blanking period and timing of reintervention remain areas of active investigation.
Avoids early reintervention for ERAA; leaves open optimal blanking period duration and reablation timing for prospective trials.
Early recurrence of atrial arrhythmias (ERAA) after ablation is common and strongly predicts late recurrences and ablation failure. However, since arrhythmia may eventually resolve in up to half of patients with ERAA, guidelines do not recommend immediate reintervention for ERAA episodes occurring during a 3-mo post-ablation blanking period. Certain clinical demographic, electrophysiologic, procedural, and ERAA-related characteristics may predict a higher likelihood of long-term ablation failure. In this review, we aim to discuss potential mechanisms of ERAA, and to summarize the clinical significance, prognostic implications, and treatment options for ERAA.

Liang et al. (2016) conducted a review in Atrial fibrillation. Catheter ablation was evaluated. Early recurrence of atrial arrhythmias after catheter ablation is common and strongly predicts late ablation failure, though optimal management during the 3-month blanking period remains undetermined.
