Outcomes of Transcatheter Aortic Valve Replacement in Mixed Aortic Valve Disease: A Comparison Between Bicuspid and Tricuspid Valves.
Article in Journal of the American Heart Association, 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
backgroundThe impact of aortic valve morphology on outcomes after transcatheter aortic valve replacement in patients with mixed aortic valve disease, characterized by the coexistence of aortic stenosis and regurgitation, remains poorly defined. This study aimed to compare outcomes of transcatheter aortic valve replacement between bicuspid and tricuspid aortic valve morphologies in patients with mixed aortic valve disease.
methodsWe retrospectively analyzed 282 patients with mixed aortic valve disease who underwent transcatheter aortic valve replacement between January 2019 and June 2024, including 82 with bicuspid aortic valve and 200 with tricuspid aortic valve. Propensity score matching at a 1:1 ratio yielded 82 well-balanced pairs. The primary end point was all-cause death, and secondary end points included technical success, paravalvular leak, clinical adverse events, hemodynamic performance, and left ventricular reverse remodeling.
resultsBoth groups achieved high technical success rates (97.6% versus 93.9%;
conclusionsIn patients with mixed aortic valve disease undergoing transcatheter aortic valve replacement, bicuspid aortic valve morphology was associated with more mild or greater paravalvular leak but similar procedural safety, hemodynamic outcomes, and clinical prognosis compared with tricuspid aortic valve, with distinct left ventricular recovery patterns.
