“Grown-Up” Congenital Heart Disease and Sudden Death in a Medical Examiner’s Population*
Bibliographic record
Abstract
Despite advances in the management of congenital heart disease (CHD), children with CHD who survive into adulthood are at increased risk of sudden death. Sudden death may also be the initial presentation of undiagnosed CHD in some adults. This retrospective descriptive study outlines the spectrum of CHD presenting as sudden death in adults in a medical examiner's population. Despite its rarity (0.2% of all cases investigated between 1991 and 2007), CHD remains an important cause of sudden cardiac death to be recognized at adult autopsy. Bicuspid aortic valve and anomalous coronary anomalies were the most common malformations, comprising 36.9% and 26.2% of cases, respectively. However, a wide spectrum of simple to complex malformations can be seen, with or without prior surgery, and over a wide age spectrum. Once solely a pediatric entity, CHD is now "grown-up" and will likely be diagnosed by forensic pathologists with increased frequency in the future.

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.
