Long-term Outcomes of Standardized Strategy in Arterial Switch Operation: An 18-Year Review in a Single Center.
Article in Korean circulation journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 AND
objectivesDespite advances in the outcomes of arterial switch operation (ASO), long-term complications such as neo-aortic regurgitation (AR), neo-aortic root dilatation (ARD), neo-pulmonary stenosis (PS), and coronary artery-related events (CARE) pose challenges. We aimed to evaluate the long-term outcomes of ASO following a consistent surgical strategy adopted since 2003.
methodsWe retrospectively analyzed 133 patients who underwent ASO between January 2003 and June 2021. Consistent surgical strategies included the trap-door method for coronary artery transfer, preservation of the neo-sinotubular junction, and extensive mobilization of pulmonary artery branches. Clinical outcomes and risk factors for adverse events were assessed.
resultsAmong the 133 patients, 64 had transposition of the great arteries (TGA) with intact ventricular septum (IVS), 52 had TGA with ventricular septal defect (VSD), and 17 had Taussig-Bing anomaly (TBA). Operative mortality was 5.2% (n=7), with no late mortality over a median follow-up of 7.1 years. Freedom from reoperation and the composite of reoperation and re-intervention rates at 15 years were 80.7% and 74.0%, respectively. Freedom from significant neo-AR (≥ mild-to-moderate), neo-ARD (z-score ≥3.0), neo-PS (peak velocity >3.0 m/s or requiring re-intervention), and CARE at 15 years was 91.7%, 37.1%, 77.7%, and 92.3%, respectively. Complex TGA morphological subtypes (TBA > TGA-VSD > TGA-IVS) had higher neo-ARD (log-rank p<0.001) and composite of reoperation and re-intervention rates (log-rank p=0.021).
conclusionsOur surgical outcomes of ASO following the standardized strategy were favorable, despite concerns regarding long-term adverse events. Complex TGA morphological subtypes demonstrated higher neo-ARD and composite of reoperation and re-intervention rates.
