Abstract

fetched live from OpenAlex

The basic elements of a standard transthoracic echocardiography (TTE) examination are 2D images supplemented by Doppler and color Doppler information in multiple orthogonal imaging planes. The use of M-mode echocardiography is reserved primarily for the assessment of ventricular performance, although some current pediatric recommendations call for 2D assessment of left ventricular size and function. A complete transthoracic pediatric echocardiogram should include a quantitative assessment of left ventricular size and systolic function. The five standard views of a pediatric TTE are all employed as part of a routine examination including subxiphoid, apical, parasternal, suprasternal notch, and right parasternal. Supplemental imaging from the “flanks” is indicated when early postoperative examinations are performed. The measurement of cardiac structures and flows is critical to the interpretation of a pediatric echocardiogram. The measurements that are “relevant” in pediatric patients will vary depending upon the specifics of their cardiovascular anatomy.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
