2D-Echocardiographic Estimation of Right Ventricular Volumes Using a Previously Validated Geometric Model Is Associated With Outcomes After Transcatheter Tricuspid Interventions.
Article in Echocardiography (Mount Kisco, N.Y.), 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
aimsTo determine whether a simplified, previously proposed two-dimensional (2D) approach to RV volume assessment can provide adjunctive prognostic information in patients undergoing Transcatheter Tricuspid Valve Interventions (TTVI). METHODS AND
resultsIn this prospective single-center study, 113 patients undergoing TTVI were included (T-TEER; n = 91, heterotopic caval valve implantation; n = 17, and orthotopic transcatheter tricuspid valve replacement; n = 5). RV end-diastolic and end-systolic volumes were calculated using a previously described 2D-based geometric model. The primary endpoint was a composite of all-cause mortality or rehospitalization for acute decompensated heart failure at 1 year. The primary endpoint occurred in 47 patients (41.6%). In univariable Cox regression analysis, both RVEDVi (HR 1.05 per 10 mL/m
conclusionRV volumes derived from a simple 2D echocardiographic model are associated with clinical outcomes and may provide additional information for the assessment of patients undergoing TTVI.
