Iatrogenic extra-pleural haematoma following cardiac device implantation
Bibliographic record
Abstract
A 67-year-old gentleman with dilated cardiomyopathy, decreased ejection fraction (18%), and left bundle branch block underwent an uneventful cardiac resynchronization therapy-defibrillator (CRT-D) implantation. He was treated with clopidogrel 75 mg/day. Post-operatively (Panel A), a chest radiograph revealed an opacity over the left hemithorax. A computed tomography scan further characterized a large (25.4 cm diameter) fluid collection in the extra-pleural space, extending superiorly and anteriorly. The suspected mechanism was an inadvertent arterial puncture of a subclavian artery branch (probably <0.3 mm diameter). Interventional radiology performed an angiogram targeting the left subclavian artery (Panel B). A small blush of contrast was identified, and a 10 cm long Gore Viabahn stent was deployed. Arterial extra-pleural haematoma can be a complication of CRT-D implantation warranting prompt recognition and resolution. Conflict of interest: none declared.

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.
