Anomalous Left Anterior Descending Coronary Artery Arising From the Right Coronary Artery: A Case Report
Bibliographic record
Abstract
Congenital anomalous coronary artery origins are rare, with a prevalence of 0.24-1.6%. Common configurations include left circumflex arising from the right coronary (RCA), left main coronary arising from the right coronary sinus and independent ostia for the left anterior descending (LAD) and left circumflex. One rare configuration that is not well described is the LAD arising from the RCA. A 68-year-old patient presented with non-ST elevation myocardial infarction, underwent coronary artery bypass grafting and was found to have a patent LAD arising from the RCA. In patients presenting with coronary artery disease and anomalous coronary anatomy, careful preoperative planning and intraoperative attention to patient anatomy is essential in identifying high-risk coronary anomalies and providing the correct and optimal treatments for these patients.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
