Myocardial Protection Efficacy of Custodiol, Del Nido, and Cold Intermittent Blood Cardioplegia in Arterial Switch Operation.
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. 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
objectivesThe arterial switch operation (ASO) is the standard treatment for transposition of the great arteries (TGA), requiring robust myocardial protection due to the neonatal myocardium's vulnerability to ischaemia. This study compares the myocardial protective efficacy of Custodiol, Del Nido, and cold intermittent blood cardioplegia in neonates undergoing ASO.
methodsWe retrospectively analysed 133 neonates with TGA undergoing ASO (2013-2024) at 4 Turkish centres, grouped by cardioplegia: cold blood (n = 47), Custodiol (n = 44), or Del Nido (n = 42). Outcomes included aortic cross-clamp and cardiopulmonary bypass times, troponin I, CK-MB, inotropic support, and ventilation duration.
resultsCustodiol and Del Nido had shorter cross-clamp (70.4 (8.5) vs 68.7 (7.9) vs 78.2 (9.1) minutes, P < .001) and bypass times (P = .004), lower troponin I (4.2 (1.3) vs 4.0 (1.5) vs 6.8 (1.9) ng/mL, P < .001), reduced inotropic needs (P < .001), and shorter ventilation/intensive care unit stays (P ≤ .010). Mortality was similar (P = .47).
conclusionsCustodiol and Del Nido cardioplegia strategies provided favourable outcomes compared to cold blood cardioplegia in neonates undergoing ASO, with implications for optimizing myocardial protection protocols in this population.
