ALCAPA in an Octogenarian Woman: An Enigma
Bibliographic record
Abstract
ALCAPA syndrome (anomalous origin of the left coronary artery from the pulmonary artery) is an exceedingly rare disease but lethal with clinical expression from myocardial infarction, congestive heart failure to death during early infancy and rare survival to adulthood. A 75-year-old woman with ALCAPA syndrome presented with angina (Canadian Cardiovascular Society functional class II) over past 8 months. Physical examination was within normal limits except pan-systolic murmur at the apex. Electrocardiography displayed poor R progression in precordial leads and signs of left ventricular hypertrophy. Echocardiography established presence of continuous flow entering the pulmonary trunk and normal systolic function. Coronary angiogram showed absence of left coronary artery originating from aorta, dilated and tortuous right coronary artery (RCA) and abundant Rentrop grade 3 intercoronary collateral communicating with left coronary artery originating from pulmonary trunk which was also confirmed on CT angiogram thus establishing diagnosis of ALCAPA. Survival in eight decade with this anomaly is still an enigma.

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.
