Direct Epicardial Mapping and Ablation Revealing Three-Dimensional Roof-Dependent Macroreentrant Atrial Tachycardia Breaking Into Bachmann's Bundle.
Article in Clinical case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Catheter ablation for macroreentrant atrial tachycardia (AT) that recurs after atrial fibrillation (AF) ablation is occasionally difficult because of epicardial connections. Here, we report the case of a patient who underwent ablation for recurrent AT after AF ablation. Endocardial mapping of the left atrium (LA) showed a centrifugal pattern from the base of the appendage, and the LA roof showed discontinuous activation from the posterior LA. Direct epicardial mapping was performed, revealing the roof-dependent macroreentrant AT using the epicardial connection from the LA posterior to the Bachmann bundle. The entrainment pacing from the exit site of the epicardium was within the tachycardia circuit, and epicardial ablation successfully terminated the AT. Epicardial mapping and ablation can improve the procedural success rate of reentrant AT recurrence after endocardial ablation.
