Case Report: Right-atrial reverse remodeling causing resolution of new-onset torrential tricuspid regurgitation after successful rhythm control.
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
In patients with persistent atrial fibrillation, adverse atrial remodeling may induce annular enlargement causing severe mitral- or tricuspid valve regurgitation and heart failure symptoms. Herein, we describe a case of rapidly progressive right atrial (RA) adverse remodeling due to new onset persistent AF, causing tricuspid annular dilatation and torrential tricuspid regurgitation (TR) in a 79-year-old female patient. This condition could be diagnosed by echocardiography, which helped guiding further patient management. After successful electric cardioversion, reverse RA remodeling took place, resulting in resolution of RA enlargement, TR and clinical symptoms within a few weeks. To maintain sinus rhythm, the patient underwent cryoablation and her further clinical course was uneventful.
