Real-World Outcomes of Repeat Ablation Strategies for Atrial Fibrillation: Insights From the Japanese Catheter Ablation Registry.
Article in Journal of arrhythmia, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03729232 (Japanese Catheter Ablation Registry), which is not on this map. Cited by 1 paper.
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.

Abstract
Background: Repeat ablation is often required in patients with atrial fibrillation (AF) due to recurrent arrhythmias. Although pulmonary vein isolation (PVI) is the only recommended ablation technique for repeat ablation, various additional strategies are commonly used in clinical practice. The purpose of this study was to evaluate the implementation, efficacy, and safety of repeat ablation strategies in Japan. Methods: This study was conducted by using the Japanese Catheter Ablation Registry (J-AB registry). A total of 26 684 patients who underwent a second ablation procedure for AF between August 2017 and December 2020 were included and analyzed for patient characteristics, procedural characteristics, and complications. Additionally, the AF recurrence rate over a 12-month follow-up period was also investigated in 1508 s ablation procedures. Results: In the second ablation procedure, repeat-pulmonary vein isolation (re-PVI) was performed for 20 938 (78%) patients and 14 552 (55%) patients underwent left atrial additional ablation. Both of re-PVI and left atrial additional ablation were performed for 10 086 (38%) patients. As the number of left atrial additional ablations in the second ablation procedure increased, the overall complication rate also significantly increased (paroxysmal AF, Conclusions: In the second ablation procedure performed in Japan, re-PVI was required in 78% of patients, and both of re-PVI and left atrial additional ablation were performed for 38% of patients. As the number of left atrial additional ablations increased, the overall complication rate also increased. Trial Registration: The J-AB registry is registered in the UMIN Clinical Trial Registry (UMIN 000028288) and ClinicalTrials.gov (NCT03729232).
