Percutaneous occlusion of a pulmonary aneurysm causing hemoptysis in a patient with pulmonary atresia and aortopulmonary collaterals
Bibliographic record
Abstract
A 28-year-old male was referred for cardiac catheterization because of recurrent severe hemoptysis necessitating resuscitation and subsequently preventing weaning from ventilation. He had a history of pulmonary atresia, ventricular septal defect, overriding aorta with right-sided aortic arch diagnosed at birth. Eisenmenger's syndrome ensued and he was not felt to be suitable for corrective cardiac surgery. He had multiple major aortopulmonary collateral vessels to both lungs with a large aneurysm in an artery to the right lower lobe, which was suspected to be the source of his bleeding. Occlusion of this aneurysm was achieved percutaneously using an Amplatzer septal occluder device. He had no further bleeding and was successfully weaned from ventilation. Six months later, he has recovered to his functional baseline and has not had any further episodes of hemoptysis.
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.

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.
