ALCAPA and ASD Secundum Unmasked by Severe Postpartum Haemorrhage Complicated by Heart Failure
Bibliographic record
Abstract
Abnormal Left Coronary Artery from Pulmonary Artery (ALCAPA) is a rare congenital coronary anomaly in which the left main coronary artery arises from the pulmonary trunk, resulting in a left to right shunt. ALCAPA is associated with septal defects and patent ductus arteriosus. The case discussed had a secundum atrial septal defect. Sudden cardiac death is a feared complication. We discuss the hemodynamics of this shunt combination and outline its management, emphasizing shunt hemodynamics during pregnancy. This case highlights that pregnant patients with ALCAPA are at high risk and require optimal peri- and postpartum care. After surgical establishment of dual coronary circulation, patients have carried subsequent pregnancies to term.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
