Atrial-secondary tricuspid regurgitation: a better prognosis in early stage heart failure, but not in late stage.
Article in ESC heart failure, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
BACKGROUND AND
aimsAlthough the classification of secondary tricuspid regurgitation (STR) by atrial or ventricular aetiology (A-STR or V-STR) carries prognostic importance, the confounding effects of New York Heart Association (NYHA) class have not yet been elucidated. We aimed to correlate STR and NYHA classification with patient outcomes.
methodsWe studied 281 patients with severe STR who presented to 16 French hospitals between 2017 and 2019. Patients were separated into A-STR and V-STR categories using echocardiographic criteria (A-STR = tricuspid tenting height ≤10 mm, right mid-ventricular diameter ≤38 mm, and LVEF ≥ 50%). We tracked time to cardiovascular disease-related hospitalization or death, whichever came first.
resultsOf the patients 91/281 (32.7%) had A-STR, 164/281 (58.4%) had mixed/V-STR, and 25/281 (8.9%) could not be classified. Baseline age, labs, comorbidities and NYHA category (Class I-II = mildly symptomatic, Class III-IV = very symptomatic) did not differ between groups (P > 0.05). Although there were no differences in event-free survival among groups (70.7% vs. 65.9%, P = 0.59), this was confounded by NYHA class (P = 0.0104). Thus, among mildly symptomatic patients, estimated 5 year event-free survival was 76.4% in the A-STR group and 53.2% in the mixed/V-STR group (P < 0.05). Among very symptomatic patients, there was no difference in estimated event-free survival (39.4% vs. 17.2%, P > 0.05).
conclusionsThough A-STR carries a more favourable prognosis in mildly symptomatic patients, this distinction is irrelevant in patients with advanced disease. Thus, the value of tricuspid valve intervention may become 'too little, too late' if A-STR is not promptly addressed.
