108 * INITIAL MANAGEMENT OF PULMONARY BLOOD FLOW IS ASSOCIATED WITH LATE OUTCOMES IN TRICUSPID ATRESIA
Bibliographic record
Abstract
Objectives: To determine the association between survival and surgical management of pulmonary blood flow (PBF) at index procedure in tricuspid atresia (TA). Methods: Infants with TA (n = 303) were enrolled from 34 institutions (1999–2013). Among infants with surgical intervention (n = 302), the index procedures included Blalock-Taussig shunt (mBT; n = 189, 62%), pulmonary artery banding (PAB; n = 50, 17%) or superior cavopulmonary connection (SCPC; n = 63, 21%). Parametric multiphase risk-adjusted models were used to analyse competing outcomes. Results: Risk-adjusted 1-year survival was lower after mBT (90%) versus PAB (97%) or SCPC (97%) (P = 0.04). Poor survival without SCPC after mBT was associated with a lower immediate post-procedure (prior to extubation) oxygen saturation (Fig. 1). Post-mBT survival was also significantly lower when the ductus remained open post- procedure (n = 7; 97% vs 76%; P = 0.02). mBT origin from the subclavian artery trended toward worse survival than origin from the innominate (IA) (87% vs 94%; P = 0.1). Conclusion: TA patients with mBT represent a high-risk subgroup. Through mechanisms not fully understood, concomitant PT intervention at mBT is associated with increased risk of death which continues after transition to SCPC.

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.
