Abstract
Mixed aortic valve disease, defined as the combination of aortic stenosis and regurgitation, is a frequent condition for which a poor prognosis has recently been demonstrated, likely as a result of its specific pathophysiology. Echocardiography, based on consecutive evaluation of stenosis, regurgitation, and global effects caused by the valve disease, is the diagnostic cornerstone of severity assessment, but advances in imaging, including speckle-tracking echocardiography, multidetector computed tomography, and cardiac magnetic resonance, may improve the diagnostic yield. Current surgical or transcatheter management is mainly based on criteria used for isolated stenosis or regurgitation, including symptoms and left ventricular dilatation and/or dysfunction, but emerging evidence tends to support earlier management. Ideally, a randomized trial in asymptomatic patients with preserved ejection fraction would be needed to evaluate the potential benefit of this approach.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
