Focal atrial tachycardia from the superior vena cava following atrial fibrillation cryoablation: a case report.
Article in Frontiers in cardiovascular medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
A 58-year-old woman with recurrent paroxysmal atrial fibrillation and a history of cryoablation 3 years prior underwent an electrophysiological study for an irregular narrow complex tachyarrhythmia. The electrocardiogram showed positive P' waves in all leads except aVR, with the P' waves separated by large isoelectric intervals, indicating focal atrial tachycardia rather than atypical atrial flutter. High-resolution 3D mapping revealed a focal atrial tachycardia originating from the postero-septal part of the superior vena cava (in close proximity to the right superior pulmonary vein). Three applications at the superior vena cava level terminated the tachycardia and restored sinus rhythm. There were no recurrences. This case underscores the need for high-resolution electrophysiological mapping to identify the arrhythmia origin, especially in patients with prior procedures.
