Intra-cardiac cement embolism during hip arthroplasty
Bibliographic record
Abstract
A 92-year-old woman presented to the operating room with a right femoral neck fracture. She had a past medical history significant for atrial fibrillation, coronary artery disease with a history of coronary bypass, severely stenotic aortic valve (area 0.9 cm2), diabetes, dyslipidemia, hypertension and dementia. She underwent general anesthesia with continuous Transesophageal Echocardiographic (TEE) monitoring for a right hemi-arthroplasty. While cementing the prosthesis, small cement emboli were initially seen (ME ascending aorta SAX view) migrating in the pulmonary artery (Figure A*). Subsequently, a large (4 cm) cement embolus was visualized in the right atrium, adhered to the Eustachian valve, an embryonic remnant (Figure B*, supplementary video A). The patient experienced no significant hemodynamic compromise or issue with gas exchange. Given embolization risk and severe potential for harm, intervention may be indicated. Treatment options were discussed but given hemodynamic stability, patient age and comorbidities, the patient was monitored without further intervention.
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.
