CAN ISOLATED VENTRICULAR INVERSION SURVIVE WITHOUT ATRIAL OR VENTRICULAR SEPTAL DEFECT?- CASE REPORT
Bibliographic record
Abstract
Background : Isolated ventricular inversion is characterized by atrioventricular discordance and ventriculoarterial concordance, clinically akin to transposition of the great arteries. 1 In the absence of a significant atrial or ventricular septal defect, profound cyanosis is expected at birth. Case Report: A 5-month-old infant with isolated ventricular inversion presented with mild cyanosis. The left sided tricuspid valve straddled the interventricular septum with a closed interventricular communication, a type of “Double Outlet Left Atrium with three atrioventricular valves”, which provided the necessary ‘left to right’ shunt while severe regurgitation through the straddling segment and a patent ductus arteriosus provided the effective pulmonary blood flow. 2 Result : The infant underwent atrial septectomy, closure of the leaky accessory orifice and a Damus-Kaye-Stansel anastomosis and a bidirectional Glen operation. Conclusion: A unique natural mechanism permitting survival in a child with transposition physiology is described. The Damus procedure preserved tricuspid valve, right ventricle and pulmonary valve function.

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.
