Single Coronary Artery With Anomalous Origin From the Right Sinus Valsalva: A Rarity in the Catheterization Laboratory
Bibliographic record
Abstract
A single coronary artery is a rare congenital anomaly with an incidence of 0.02%. We report a 74-year-old Caucasian female presenting with angina pectoris, effort dyspnea and a history of hypertension and hypercholesterolemia, being diagnosed with a very rare variant of a single coronary artery arising from the right sinus of Valsalva continuing as right coronary artery (RCA) and thereafter as left anterior descending coronary artery (LAD). Because the patient was asymptomatic with ischemic medication and had a proposed relative benign course, we recommended medical treatment without coronary artery bypass surgery. Twelve months after angiography the patient has been in fine condition and asymptomatic under medical treatment. Cardiologist should keep in mind that patients with coronary artery anomalies are usually asymptomatic. They may develop clinical symptoms like syncope, angina pectoris, ventricular arrhythmias, myocardial infarction and sudden death. The treatment strategy for single coronary artery is still not clear. doi:10.4021/jmc239e

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.
