Management options in neonates and infants with critical left ventricular outflow tract obstruction
Bibliographic record
Abstract
Despite being one of the most common congenital cardiac abnormalities, the treatment of critical left ventricular outflow tract obstruction (LVOTO) in the neonate and infant remains a significant challenge. Critical LVOTO in the neonate and infant includes continuous and diverse spectrum of anatomic diagnoses ranging from hypoplastic left heart complex to isolated aortic valvular stenosis with otherwise normally formed left heart structures. Depending on related anatomic features, there are multiple single ventricle and biventricular management strategies available for patients with critical LVOTO; all of which carry significant risk of death and requirement for future interventions. Because of the wide array of morphologic lesions and physiologic manifestations, application of the currently available published data to guide decision making in the individual patients can be challenging. Therefore, the aim of this review is to describe the different therapeutic strategies that can be applied to neonates presenting with critical LVOTO taking into consideration each patient's unique physiologic and anatomic findings.

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.
