Management of tetralogy of fallot in developing countries: opportunities and challenges for surgeons.
Article in Journal 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
backgroundThis study evaluates outcomes of Tetralogy of Fallot (TOF) correction, focusing on survival, complications, and management insights in a developing country setting.
methodsThis cohort retrospective study analyzed medical records of patients with TOF undergoing total correction (April 2024-April 2025). Variables included demographics, McGoon ratio, Cardiopulmonary Bypass (CPB), Aortic Cross Clamp (AOX), Length of Stay (LOS), morbidity, and mortality. Data were analyzed with chi-square and Mann-Whitney tests (p < 0.05).
resultsAmong 43 patients with TOF undergoing late total correction, mortality was 11.6%, higher than reported rates in low- and middle-income countries. Most cases presented late (mean age 9.19 years), underweight (65.1%), and hypoxemic (SpO₂ <90% in 79.1%). Predominant subvalvar stenosis led to prolonged CPB and AOX times. Deaths occurred only in children < 2 years. Limited Intensive Care Unit resources and delayed referral likely worsened outcomes, underscoring the need for early surgery, nutrition support, and infection control.
conclusionDelayed referral and limited early detection within the community should not preclude surgical correction in patients older than one year. With appropriate perioperative management, favorable outcomes remain achievable despite late presentation. PRACTICAL IMPLICATIONS: Enhancing preoperative optimization, perioperative management, and postoperative care could improve late-repair outcomes and align results with global standards.
