Recurrence of Atrial Fibrillation After Repeat Catheter Ablation: A Systematic Review and Meta-Analysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Catheter ablation is a key treatment for atrial fibrillation (AF); however, recurrence often requires repeat procedures. This meta-analysis evaluates the efficacy of repeat ablation for recurrent atrial arrhythmia, focusing on ablation technique, anatomical targets, and pulmonary vein (PV) reconnection. Methods: A systematic literature search of MEDLINE, Scopus, and Cochrane Central Register of Controlled Trials was conducted on studies assessing repeat and initial ablation outcomes until February 2025. Data on atrial arrhythmia recurrence, ablation technique, targets, and PV reconnection were extracted. A random-effects model meta-analysis was used to estimate the pooled recurrence rate after repeat ablation. Results: Fifty-three studies (8,117 patients) were included. The recurrence rate after repeat ablation was 30% (95% confidence interval [CI]: 27%-34%), with PV reconnection observed in 90% of cases following the initial ablation. The lowest recurrence rate was observed with cryoballoon ablation (CBA) followed by radiofrequency ablation (RFA) at 23% (95% CI: 15%-33%, I Conclusions: Repeat ablation for AF was associated with the risk of recurrence, mainly due to PV reconnection. Strategies involving CBA followed by RFA and PVI-based approaches showed favorable outcomes, while lower reconnection rates in left-sided PVs, especially the LIPV, highlighting the need for optimized techniques.
