New Echocardiographic Algorithm for Estimating Right Atrial Pressure in Severe Tricuspid Regurgitation: Insights From Simultaneous Cardiac Catheterization.
Observational study in Journal of the American Heart Association, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
backgroundThe accuracy of echocardiographic estimation of pulmonary artery pressure has been questioned in patients with severe tricuspid regurgitation (TR). This study aimed to evaluate the accuracy of echocardiographic estimates of pulmonary artery pressure compared with simultaneous right heart catheterization (RHC) in patients with severe TR.
methodsIn this prospective observational study, a total of 48 patients with severe TR were enrolled between September 2021 and August 2024 at an experienced RHC center. Data were obtained by simultaneously measuring echocardiography and RHC parameters. The correlation between pulmonary arterial systolic pressure (PASP) measured by echocardiography and RHC was analyzed using Pearson correlation and Bland-Altman analysis.
resultsThe median age was 71.5 years, and 26 (54.2%) of the patients were women. Forty-three (89.6%) patients had secondary TR as the underlying pathogenesis. There was a good correlation (
conclusionsEchocardiography demonstrated good agreement with invasively measured PASP. Incorporating additional echocardiographic parameters significantly enhanced the accuracy of PASP estimation, suggesting a refined noninvasive diagnostic approach in severe TR.
