Pathologically Proven Papillary Fibroelastomas Attached to the Left Atrial Appendage and Pulmonary Vein Ridge.
Article in JACC. Case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Papillary fibroelastomas (PFEs) are the most common benign cardiac tumors, typically found on valvular surfaces but less frequently on extravalvular structures. Despite their benign nature, PFEs are associated with serious embolic events. This study analyzes 13 cases of pathology-proven PFEs in the left atrial appendage (LAA) and pulmonary vein ridge. Data on patient demographics, clinical presentations, imaging, and histopathology were reviewed. The median patient age was 73 years, with slight male predominance. Tumor sizes ranged from 2 mm to 20 mm. Twelve PFEs were detected via transesophageal echocardiography, and neurologic events were observed in 4 patients. This case series emphasizes the importance of maintaining a broad differential diagnosis for LAA masses because PFEs can easily be mistaken for thrombi.
