A case of aortopulmonary window mimicking common arterial trunk on fetal echocardiography
Bibliographic record
Abstract
Aortopulmonary window (APW) is a rare congenital cardiac anomaly characterised by abnormal communication between the aorta and the pulmonary trunk in the presence of separately formed semilunar valves.We present a case that was initially diagnosed in prenatal life at 21 weeks as common arterial trunk.Follow-up scans starting from 31 weeks revealed APW type I in the setting of tetralogy of Fallot (S, D, S) with a right-sided aortic arch with wide interatrial communication.The neonate was born at 38 weeks of gestation by caesarean section; its birth weight was 2825 g.The postnatal echocardiogram confirmed the prenatal diagnosis provided later in gestation.Three weeks after birth, the child was scheduled for surgery: complete repair and APW closure using an autologous pericardial patch, excision of trabeculae in the right ventricular outflow tract (RVOT), transannular reconstruction below the RVOT, reconstruction of the RVOT, and partial ASD closure.The child was discharged from the hospital, weighing 3300 g, with 97% saturation.APW may remain undiagnosed until adulthood.A late diagnosis may result in congestive heart failure and irreversible damage to the pulmonary vessels.Early detection of APW, preferably in the prenatal period, remains the key issue in terms of this condition.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
