Case Report: A cardiac mass diagnosed using Point-of-care ultrasound in a dyspneic patient. An integrated ultrasound examination of lung-heart-Inferior Vena Cava
Bibliographic record
Abstract
A 74-year-old woman with history of hypertension presented to the Emergency Department (ED) with severe resting dyspnea and swelling in the feet, ankles and legs. She was on treatment with furosemide and a beta blocker. At the time of admission blood pressure was 145/88 mmHg, heart rate (HR) 99 bpm, regular, oxygen saturation was 89% (FiO2 21%) and respiratory rate was 17 breaths/min. Abbreviation List AST: Aspartate aminotransferase ED: Emergency Department GFR: Glomerular Filtration Rate HCC: Hepatocellular Carcinoma HF: Heart Failure HR: Heart rate IVC: Inferior vena cava LAFB: Left anterior fascicular block LV: Left ventricle NT-pro-BNP: N-Terminal pro-Brain Natriuretic peptide POCUS: Point-of-care ultrasound RA: Right atrium RBB: Right bundle branch block RV: Right ventricle TS: Tricuspid stenosis

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.
