Tricuspid Annuloplasty: Is It a Step That Should Not Be Ignored in Mitral Valve Surgery?
Article in Interdisciplinary cardiovascular and thoracic 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
objectivesTricuspid regurgitation (TR) is commonly encountered in patients with left-sided valve disease and often progresses postoperatively if left unaddressed. While mitral valve replacement (MVR) alone may improve left heart parameters, concomitant tricuspid ring annuloplasty (TRA) might prevent right-sided deterioration.
methodsThis retrospective study analysed 129 patients undergoing MVR between 2016 and 2019. Patients were divided into 2 groups: isolated MVR (n = 71) and MVR + TRA (n = 58). Long-term echocardiographic outcomes were compared, including LVDD, LVSD, LVEF, LA diameter, IVS thickness, pulmonary flow rate, PAP, and TI degree.
resultsBoth the groups showed regression in left heart dimensions postoperatively; however, left ventricular ejection fraction (LVEF) significantly decreased in the MVR-only group (P < .001) while it remained stable in the MVR + TRA group (P =0.598). Severe tricuspid insufficiency occurred in 12% (95% CI 5%-21%) of patients undergoing isolated MVR and 0% (95% CI 0%-6 ) of those undergoing MVR + TRA (P < .001). The mean difference in the change of pulmonary artery pressure (ΔPAP) between the groups was 12.0 mmHg (95% CI 6.5-17.3, P = .002), and both pulmonary artery pressure and left atrial diameter significantly decreased postoperatively in the MVR + TRA group.
conclusionsPerforming TRA during MVR surgery offers significant protective effects against TI progression and right heart overload. Even in cases with mild TI but annular dilation, simultaneous TRA may be a rational and beneficial strategy to ensure long-term cardiac stability.
