Combined transcatheter mitral and tricuspid edge-to-edge repair or tricuspid edge-to-edge repair alone in moderate mitral regurgitation: a propensity-matched analysis.
Article in European heart journal, 2026. 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
aimsThe coexistence of moderate mitral regurgitation (MR) and severe tricuspid regurgitation (TR) is common, yet evidence guiding optimal management remains limited. Transcatheter edge-to-edge repair (TEER) of both valves-performed either sequentially or in combination-has emerged as a potential therapeutic strategy. This study aimed to assess the prognostic impact of moderate MR in patients undergoing tricuspid TEER (T-TEER) for severe TR and to evaluate whether concomitant mitral TEER (M-TEER) improves clinical outcomes.
methodsData from the EuroTR registry (2016-25) were analysed, including patients with severe TR treated with T-TEER. Outcomes were compared between patients with untreated moderate MR and those who underwent concomitant M-TEER using propensity score matching (PSM). The primary endpoint was all-cause mortality at 2 years. Secondary endpoints included New York Heart Association (NYHA) class, 6 min walk distance (6MWD), TR severity, and heart failure rehospitalizations.
resultsAmong 3100 patients, 30% had moderate MR, which was associated with higher 2-year mortality (23% vs 37%, p<0.0001). After PSM, 217 matched patients treated with concomitant M-TEER had greater TR reduction (-1.9 vs -1.6 grades, P = .001), better NYHA improvement, and increased 6MWD at follow-up. Survival was higher in the combined treatment group (87% vs 76% at 1 year; 81% vs 70% at 2 years, P = .005). In a multivariable analysis, moderate MR predicted increased mortality [hazard ratio (HR) 1.81, P = .005), while combined M-TEER predicted better survival (HR 0.46, P < .0001).
conclusionsModerate MR predicts impaired prognosis in patients undergoing T-TEER for treatment of severe TR. Concomitant M-TEER is associated with improved survival and functional outcomes in this population with multivalve disease. These findings are hypothesis-generating and need to be tested in a dedicated randomized controlled trial.
