Percutaneous recanalization of totally occluded coarctation of the aorta in children using Brockenbrough needle and covered stents
Bibliographic record
Abstract
Percutaneous treatment of totally occluded coarctation of the aorta has been reported predominantly in adults. The success and challenges of this procedure in children is reported in few patients. We report an outcome of percutaneous treatment of three children with completely occluded coarctation of the aorta. The age range was 9-14 years. All the patients had upper limb hypertension. One case had severe left ventricular dysfunction. In all cases, a pediatric Brockenbrough needle and a covered stent were implanted. Recanalization and implantation of a covered stent was successful in all patients. One of these patients developed transient postcoarctectomy syndrome. Percutaneous recanalization of totally occluded coarctation of the aorta using Brockenbrough needle and a covered stent in children is feasible and effective.

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.
