Pulmonary valve replacement in older children and adults using stented bioprostheses
Bibliographic record
Abstract
More than 50% of children who undergo repair of tetralogy of Fallot (TOF) using a transannular patch will require pulmonary valve replacement (PVR) in early adulthood. The premise of PVR in this setting is to ameliorate the relentless right ventricular (RV) dilatation that otherwise occurs in the presence of severe pulmonary regurgitation. Severe RV dilatation is associated with RV dysfunction, symptoms of exercise intolerance, tricuspid regurgitation and-occasionally-life-threatening RV failure or dangerous ventricular tachyarrhythmia. Increasingly, patients referred for PVR are asymptomatic young adults with busy lives and dependants. Redo cardiac surgery in this setting is high-stakes surgery. Here, we outline the surgical approach taken in a centre with a history of >1000 such operations.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
