Right atrial mass in a patient with breast cancer: percutaneous transcatheter biopsy under intracardiac echocardiography guidance
Bibliographic record
Abstract
Precise diagnosis of intracardiac masses is fundamental to their treatment. However, the findings of non-invasive imaging techniques are frequently inconclusive. In this setting, percutaneous transcatheter biopsy might represent a valid alternative to surgical biopsy. Intracardiac echocardiography (ICE)-guided biopsy offers high-quality imaging, is a relatively quick and easy interventional procedure to perform and does not require patient intubation or the assistance of an echocardiographer. We describe the case of a 47-year-old woman undergoing chemotherapy for breast cancer, who presented with a right atrial mass. Non-invasive imaging was inconclusive. Since no changes in the aspect or size of the mass were noticed after 2-week treatment with heparin, ICE-guided biopsy was performed, which confirmed the thrombotic nature of the mass. The patient underwent surgical resection of the thrombus and curative treatment of her breast cancer was pursued.

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.
