Left Circumflex Aneurysm With Coronary Sinus Fistula In a Middle-aged Man: A Case Report
Bibliographic record
Abstract
Coronary artery aneurysms (CAAs) and coronary artery fistulas (CAFs) are rare abnormalities. CAA is an abnormal dilatation of the coronary artery while CAF is an unusual connection between a coronary artery and other cardiac structures. We report a case of a 55-year-old male with a history of atrial fibrillation and mitral regurgitation who was diagnosed with a left circumflex artery aneurysm, with a fistula connecting to the coronary sinus. He subsequently underwent an aneurysm resection, along with coronary artery bypass grafting (CABG) and mitral valve replacement. In this case report, we underscore the importance of early identification of this rare condition, as timely intervention mitigates potential complications, including coronary aneurysm rupture.

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.
