Severe Trileaflet Aortic Stenosis Without Significant Valve Calcification in an Older Adult.
Article in Methodist DeBakey cardiovascular journal, 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
Severe aortic stenosis (AS) is most often caused by progressive valve calcification; however, rare cases occur with little or no calcification. We report a 79-year-old man with a trileaflet aortic valve and progressive, hemodynamically severe AS despite an almost complete absence of valve calcification (aortic valve calcium score of 76.5 Agatston units). Multimodality imaging confirmed the severity of obstruction, and the patient underwent successful surgical bioprosthetic aortic valve replacement with good postoperative outcomes. This case demonstrates that severe AS can occur in elderly patients with trileaflet valves through fibrosis-predominant remodeling without significant calcification, and that computed tomography-based calcium scoring may underestimate disease severity in this rare phenotype.
