A Rare Case of Left Main Coronary Artery Atresia
Bibliographic record
Abstract
Left main coronary artery (LMCA) atresia remains one of the most rare congenital coronary anomalies. On average, there is less than one reported case each year. Because patients with LMCA atresia that make it to adulthood tend to remain asymptomatic and often are unaware of their condition, the diagnosis is often made incidentally. We report a case of LMCA atresia in a 76-year-old male with a history of seizure disorder and medication non-compliance who presented to the hospital with acute coronary syndrome in the setting of status epilepticus. Workup revealed ST elevation and minimally elevated troponin levels. Hours later, troponin levels continued to trend up, but the ST elevation resolved. Catheterization and coronary angiography revealed a dominant right coronary artery and absent LMCA. Aortography confirmed the diagnosis of LMCA atresia.

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.
