Outcomes of surgical tricuspid valve intervention after heart transplant.
Article in Annals of cardiothoracic surgery, 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
Background: Tricuspid regurgitation (TR) is common following heart transplant (HTx). Data on the outcomes of tricuspid valve (TV) surgery after HTx is limited. This study evaluates the short- and long-term outcomes of TV surgery after HTx and identifies predictors of mortality. Methods: A retrospective analysis of all HTx recipients undergoing TV surgery between 2000-2019 within the Mayo Clinic Health System was performed. Demographic, echocardiographic, hemodynamic, and postoperative outcomes were collected. Survival was estimated using Kaplan-Meier analysis, and univariable Cox regression analysis was used to identify mortality-associated risk factors. Results: Forty-one patients (mean age 53.9±14.4 years) underwent TV surgery after HTx. Biopsy-related leaflet injury (22 patients) and annular dilation (16 patients) were the most common mechanisms of TR. Nine patients underwent TV surgery during the index hospitalization of HTx, while 32 patients were operated on during follow-up. After TV surgery, 5- and 10- year survival was 60.5% and 23.5%, respectively. There were 23 deaths (5 during the index hospitalization for TV surgery, while 18 died during follow-up). Preoperative predictors of mortality were elevated right atrial pressure (RAP), right ventricular end-diastolic pressure (RVEDP), and mean pulmonary artery pressure (mPAP), and international normalized ratio (INR), along with hypoalbuminemia (P<0.05). Postoperative predictors were right ventricular (RV) dysfunction, elevated RAP, RVEDP, mPAP, reduced pulmonary artery pulsatility index (PAPi), hyperbilirubinemia, and an elevated INR (all P<0.05). Conclusions: TV surgery after HTx is associated with significant early and late mortality. In HTx recipients, TV surgery should be performed before the onset of RV dysfunction and hepatic dysfunction.
