Troubleshooting a missing intra-cardiac tumor at the time of bypass
Bibliographic record
Abstract
BACKGROUND: Primary cardiac tumors are rare and the only curative treatment consists of complete excision under cardiopulmonary bypass (CPB). This case report presents an unusual case of an intra-cardiac tumor which was missing at the time of surgical excision. METHOD AND RESULTS: The patient was scheduled to undergo surgical tumor removal and double coronary artery bypass grafting (CABG). Intraoperatively, transesophageal echocardiography (TEE) demonstrated a mobile and pediculated tumor in the left ventricular outflow tract (LVOT). Unfortunately, at the time of tumor excision under CPB, this was missing. Before confirming tumor embolization, the CPB system was inspected. The tumor was found on the lateral part of the defoaming filter. CONCLUSION: Careful mobilization of the heart is recommended during surgery. In this case, it was unexpected that the tumor made its way through the vent line and unidirectional valve up to the venous reservoir where it was fortunately found.

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.
