An Unexpected Electrocardiogram in Congenital Heart Disease: A Rare Variant of a Common Cyanotic Syndrome.
Article in JACC. Case reports, 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
case summaryA 19-year-old female with a history of tetralogy of Fallot (TOF) with prior right ventricle (RV)-pulmonary artery conduit, RV outflow tract aneurysm, intermittent ventricular arrhythmia, Chiari malformation, and scoliosis presented to establish care at our institution. Electrocardiogram (ECG) demonstrated an unexpected pattern consistent with dextrocardia and right axis deviation. Further investigation noted TOF with situs inversus totalis, a rare TOF variant only previously described several times. She underwent longitudinal monitoring with progression of RV dysfunction and ventricular arrhythmias. TAKE-HOME MESSAGE: TOF produces characteristic ECG changes that have utility in monitoring RV remodeling, arrhythmogenesis, and RV volume load. When ECG presents unexpected changes, additional defects or compromised repair should be interrogated.
