A case of superior vena cava syndrome in a newborn: Importance of point of care echocardiography
Bibliographic record
Abstract
Central vascular catheterization for nutrition and monitoring is common in the current era of increasing survival of ever smaller preterm infants and their complex nutritional needs. Any foreign body in blood vessels, whether venous catheters or transvenous pacing catheters (implanted frequently in children with rhythm disorders) could put them at risk of progressive venous obstruction. Although obstruction of SVC leading to "SVC syndrome" has been widely reported in adults, it is very uncommon in children and may be associated with previous congenital heart surgery. In this case study we present SVC obstruction in a newborn infant as a complication of a central catheter. This was diagnosed by combination of clinical suspicion and typical Doppler characteristics as elucidated by application of echocardiographic skills by in-house neonatal staff.

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.
