Intraoperative urothelial carcinoma tumor thrombus embolization to the heart: a case report
Bibliographic record
Abstract
Urothelial carcinoma (UC) rarely presents with an inferior vena cava (IVC) tumor thrombus. Herein, we report the case of a patient with UC in whom the thrombus embolized to the right atrium during resection. Intraoperative echocardiography identified the large embolus measuring greater than 4 cm and prolapsing through the tricuspid valve. The tumor thrombus was removed via sternotomy. This case is significant for the following learning points: 1) tumor thrombus should be managed with care during removal as it can embolize; 2) intraoperative transesophageal echocardiography is vital in these cases; and 3) a multidisciplinary approach including cardiac surgery is imperative to ensure optimal outcomes.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
