Cardiac diverticulum with pericardial effusion: report of two new cases treated by <i>in‐utero</i> pericardiocentesis and a review of the literature
Bibliographic record
Abstract
Congenital cardiac diverticula are rare abnormalities that may occur as isolated malformations. They are often associated with pericardial effusions, which may cause both pulmonary hypoplasia and progressive fetal hydrops. Few cases are reported in fetal life. Mount Sinai Hospital, Toronto, has previously reported two cases of cardiac diverticula complicated with pericardial effusion successfully treated in utero with aspiration of the pericardial fluid. Here a further two cases of isolated apical right ventricular diverticula with large pericardial effusion, one diagnosed at 16 weeks and another at 13 weeks' gestation are described. In-utero drainage of pericardial effusion was performed once in each case at 16 and 14 weeks' gestation, respectively, with good neonatal outcome. Both had normal karyotype and there was no evidence of maternal or fetal infection. The pericardial effusion did not recur in either case. Given the otherwise favorable prognosis for this lesion, and the excellent response in these cases, prenatal pericardiocentesis should be considered in similar cases.

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.
