Abstract
The peripheral pulmonary artery stenosis (PPS) that complicates congenital heart anomalies can improve after percutaneous transluminal balloon angioplasty (PTA), despite an initial poor response, but there is little information concerning the factors that determine such remodeling. The present study reviewed the hemodynamic and angiographic data before, immediately after, and at late follow-up after PTA for 17 lesions in 14 patients. Lesions were classified into either the (+) group (with pulmonary artery remodeling) or the (-) group (without remodeling). Remodeling was defined as an increase of more than 30% in the predictive percent of normal (%N) of the peripheral pulmonary artery diameter at late follow-up compared with the diameter immediately after PTA. Remodeling occurred in 6 of 17 lesions (35%), and the pressure gradient immediately after PTA was significantly smaller (<10 mmHg) in the (+) group than in the (-) group. Late expansion of the lesion (remodeling) occurs after PTA in some children with PPS and an adequate initial reduction in the pressure gradient favors subsequent remodeling.

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
