Valvulo-Arterial Impedance in Patients with Severe Aortic Stenosis and Bicuspid Aortic Valve.
Article in Journal of cardiovascular development and disease, 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
backgroundRisk stratification in patients with bicuspid aortic valve (BAV) and severe aortic stenosis (AS) remains challenging. Valvulo-arterial impedance (Zva), an integrated marker of global left ventricular (LV) afterload, has shown prognostic value in tricuspid AS; however, data in BAV are limited. This study aimed to evaluate the association of Zva with LV remodeling, symptoms, and all-cause death in patients with BAV and severe AS.
methodsIn this retrospective, two-center cohort study, 147 patients with severe AS and BAV were included. Zva was calculated at the time of the first echocardiographic diagnosis of severe AS. The study endpoint was all-cause mortality.
resultsOver a median follow-up of 9.8 years, 24 patients (16%) died. A Zva threshold of 5 mmHg/mL/m
conclusionsAmong patients with BAV and severe AS, an increased Zva was associated with more advanced symptoms, adverse LV remodeling, impaired LV systolic function, and worse long-term survival, and might therefore help in risk stratification of these patients.
