Early Favourable Outcomes of Valve Repair in Congenital Heart Surgery.
Article in Interdisciplinary cardiovascular and thoracic surgery, 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
objectivesMechanical valve replacement is often used as the therapeutic option in valvular heart surgery in children. Evidence suggests that this should change to provide optimal long-term survival for this growing population. We reviewed our current practice in valve repair in congenital heart disease and analysed its outcomes.
methodsA total of 90 patients (30 semilunar valve and 60 atrioventricular [AV] valve) underwent valve repair between September 2020 and December 2024. Operative data and follow-up information were gathered retrospectively. Kaplan-Meier calculations were used for survival and freedom from reoperation analysis. Cox regression analysis was used to assess risk factors for mortality (single ventricle physiology, age and weight at time of surgery, bicuspid aortic valve, and complexity of repair). Complexity of repair was defined as the application of 3 or more repair techniques.
resultsEstimated survival at 12 months for semilunar and AV valve groups was 95.2% and 95%, respectively. Estimated freedom from reoperation at 12 months for repair of semilunar and AV valves was 95.8% and 95.6%, respectively. Single ventricle morphology (HR [hazard ratio], 5.2; 95% confidence interval [CI], 1.3-20.8; P = .0198) and younger age at time of surgery (HR, 0.7; 95% CI, 0.6-0.9; P = .0223) were associated with increased risk of mortality.
conclusionsValve repair in congenital heart disease provides reliable early outcomes in this complex population. The worst outcomes are expected in patients with single ventricle requiring surgery in early life.
