Indications, criterions, and principles for biventricular repair
Bibliographic record
Abstract
The hypoplastic left heart syndrome constitutes a wide spectrum of cardiac malformations, characterized by varying degrees of underdevelopment of the structures of the left heart and aortic arch. At the severe end of the spectrum, there is aortic and mitral atresia, and the left ventricle is vestigial. In contrast, at the mild end, there is hypoplasia of the left ventricle in the absence of overt stenosis of either the aortic or mitral valves, the combination we have described as hypoplastic left heart complex. 1 Until recently, debate with regard to the optimal surgical approach has centered on the choice between the Norwood operation and neonatal cardiac transplantation. In the last several years, nonetheless, it has been shown that of biventricular repair can be achieved in those patients at the favorable end of the spectrum that we designated as having the complex rather than the syndrome. 1 , 2 It is well recognized that an ongoing difficulty is the inconsistent and imprecise definition of hypoplastic left heart syndrome. In this presentation, I summarize our own criterions, and our principles for biventricular repair, as based on our experience at the Montreal Children's Hospital, for those patients we judge to have the hypoplastic left heart complex.

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.
