Asymptomatic pseudoaneurysm of the ascending aorta diagnosed due to accompanying infection of a right atrial embolus
Bibliographic record
Abstract
We present a case of a large pseudoaneurysm of the ascending aorta, originating from the purse-string suture of the cardioplegia line which was essentially asymptomatic but was diagnosed during patient follow up for fever and elevated white blood count of unknown origin. During intraoperative transesophageal echocardiography, a free floating tumor was localized in his right atrium which after removal appeared to be an infected embolus with excessive neutrophils and monocytoid cells interspersed with cell debris and fibrin. Material send for culture was positive for streptococci, whereas tissues cultures from the pseudoaneurysm were essentially negative. To our knowledge, this is the first report of an asymptomatic, non-infected aortic pseudoaneurysm which was accidentally diagnosed due to concomitant infection of an deep venous thrombus which had embolized into the right atrium.

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.
