Differences in cardiac output of patients undergoing trans-catheter aortic valve implantation according to their underlying rhythm.
Article in World journal of cardiology, 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 recent Cardiac Output in Patients with Small Annuli Undergoing Transcatheter Aortic Valve Implantation with Self-Expanding
aimTo investigate the understudied role of atrial fibrillation (AF) on cardiac output in patients undergoing TAVI.
methodsThe COPS-TAVI study enrolled consecutive patients with severe aortic stenosis and small annuli who underwent successful TAVI. Cardiac output was measured using echocardiography within 4 weeks following TAVI. Data were analyzed according to the presence of AF and stratified by SEV or BEV.
resultsA total of 138 patients were included in the analysis, of whom 22% had AF. Cardiac output was significantly lower in patients with AF compared to those without it (4.6 L/minute
conclusionCardiac output, as measured by echocardiography, was larger in patients with small annuli who underwent TAVI procedure with SEV compared to BEV in patients without AF. This observation should be considered during procedural planning.
