Risk factors for long-term severe tricuspid regurgitation following mitral valve replacement: a retrospective study.
Article in BMC cardiovascular disorders, 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
backgroundThe aim of this study is to identify factors associated with the development of long-term severe tricuspid regurgitation (TR) following mitral valve replacement (MVR).
methodsA retrospective analysis was conducted involving 308 patients who underwent single-valve MVR at Xuzhou Central Hospital between April 2017 and December 2022. Preoperative color Doppler ultrasound indicated that all patients had either no or mild to moderate tricuspid regurgitation. Postoperative follow-up was carried out over several years, and patients were categorized into two groups based on the severity of TR: 258 patients with non-severe TR (observation group) and 50 patients with severe TR (control group). Clinical data, medical history, the performance of tricuspid valvuloplasty during surgery, and echocardiographic parameters before and after the procedure were recorded. Comparative analysis between the two groups was performed, and logistic regression analysis was used to identify factors associated with the long-term development of severe TR post-MVR.
resultsLogistic regression analysis indicated that serum creatinine levels (OR = 1.023, P = 0.026), atrial fibrillation (OR = 2.780, P = 0.040), and a history of permanent pacemaker implantation (OR = 3.029, P = 0.039) were significantly associated with the development of severe TR over time. In contrast, concurrent intraoperative tricuspid valvuloplasty was associated with a reduced risk of TR (OR = 0.315, P = 0.002).
conclusionsElevated serum creatinine, atrial fibrillation, and a history of permanent pacemaker implantation were positively associated with the long-term occurrence of severe TR following MVR. In contrast, concurrent intraoperative tricuspid valvuloplasty was found to reduce the likelihood of severe TR development.
