Late Amplatzer device displacement after percutaneous PDA embolization: case description.
Bibliographic record
Abstract
A 6-month-old, 17 kg, male Labrador Retriever was presented for an evaluation of a suspected patent ductus arteriosus (PDA). Transthoracic echocardiography confirmed a left-to-right shunting PDA with a minimal ductal diameter of 3.5 mm. A transcatheter PDA occlusion was performed, and a 16 mm Amplatzer Vascular Plug II was selected for the procedure. Within 13 days of discharge, the dog developed sudden lethargy, tachypnea, and coughing after physical activity. Thoracic radiographs showed the Amplatzer device to be abnormally positioned in the lumen of the pulmonary artery with a distinct alveolar pattern. Given the progressive cardiopulmonary distress of the dog, the owners opted for euthanasia. In the present case study, the authors have not been able to satisfactorily explain why the device migrated several days after the procedure. In order to avoid device migration, greater emphasis should be placed on strict activity restriction in dogs after percutaneous PDA occlusion.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
