Quality of Life After Mitral Transcatheter Edge-to-Edge Repair According to Baseline Tricuspid Regurgitation.
Article in Structural heart : the journal of the Heart Team, 2025. 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
Background: There is a high prevalence of significant tricuspid regurgitation (TR) in patients undergoing mitral transcatheter edge-to-edge repair (M-TEER). Significant TR is associated with poor prognosis and affects decision-making between M-TEER and concomitant mitral and tricuspid valve surgery. Improved quality of life (QoL) is an important metric for patients. Methods: We analyzed data from 1838 patients undergoing M-TEER included in a multicenter statewide registry from 2015 to 2023. QoL was assessed using baseline and 30-day Kansas City Cardiomyopathy Questionnaire (KCCQ) scores. Patients were classified as no/mild TR or moderate/severe TR, and changes in KCCQ scores were compared. The primary outcome was an adjusted analysis consisting of survival to 30 days with a ≥15-point improvement in KCCQ score. Results: Complete endpoint data were available for 1421 patients (77.3%). On average, patients undergoing M-TEER experienced large improvements in QoL, regardless of baseline TR group. Thirty-day mortality for patients with moderate/severe TR was higher than for those with no/mild TR (42 [4.1%] vs. 16 [2.0%], respectively, Conclusions: The majority of patients experience a large improvement in QoL after M-TEER, regardless of baseline TR severity. Further research should explore a staged approach of M-TEER followed by tricuspid valve intervention as needed compared to concomitant mitral/tricuspid valve surgery.
