Recanalization of Atretic Aortic Arch in Teenager Guided by Cardiac Magnetic-Resonance
Bibliographic record
Abstract
BACKGROUND: Systemic hypertension secondary to total occlusion of the aortic arch is a rare etiology in children. CASE SUMMARY: This case report describes the successful management of a 12-year-old girl with an atretic aortic arch by percutaneous recanalization guided by cardiac magnetic resonance (CMR) and angiography. The orientation of the atretic segment seen by CMR suggested a percutaneous intervention would be feasible. A coronary guidewire was used to traverse the atretic arch, and a balloon-expandable covered stent was deployed to restore luminal continuity. DISCUSSION: Atretic aortic arch recanalization is a high-risk surgical procedure owing to extensive collateral circulation. CMR plays a key role in preprocedural planning, detailing the vascular anatomy as well as collateral circulation. TAKE-HOME MESSAGE: This review illustrates the important role of CMR in planning percutaneous interventions as a feasible alternative to high-risk surgical repair in complex anatomies.

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.
