Abstract
Thirteen children (seven male) with coronary artery fistula underwent percutaneous transcatheter occlusion. The age range was 8 months to 14 years (mean, 6.3 years). The fistulas had their origins from the right coronary artery (six), from the left anterior descending coronary artery (three), and from the left circumflex coronary artery (four). Drainage was to the right ventricle (seven), the right atrium (three), and one each to the pulmonary artery, left atrium, and superior caval vein. The fistulas were closed with coils in 10 patients, a Rashkind double-umbrella device in 1 patient, and an Amplatzer Duct Occluder in 2 patients. Complete occlusion was achieved in 9 of 13 patients. Complications consisted of migration of coils in four and transient arrhythmias or changes in the resting electrocardiogram in four patients. Follow-up studies 1 to 31 months (mean, 14.6 months) after occlusion noted only four patients with trivial (clinically insignificant) residual shunts. Owing to various coronary fistula morphologies, transcatheter occlusion requires availability of different embolization techniques. Short-term follow-up supports persistent clinical efficacy and transcatheter closure techniques as the initial form of therapy.

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
