Abstract
BACKGROUND: We report the successful endovascular treatment of a coronary graft pseudoaneurysm using a technique often seen in intracranial aneurysm coiling. CASE SUMMARY: We present an unusual case of a patient who presents with haemopericardium and haemodynamic instability after saphenous vein bypass grafting. A pseudoaneurysm rapidly expanded from 5 cm to 7 cm over the follow-up period producing compressive mass effect on the lateral right ventricle with transient haemodynamic instability. The patient's declining clinical condition did not warrant a redo thoracotomy and sternotomy, so an endovascular approach was deemed to be the best treatment option. DISCUSSION: The use of endovascular embolization techniques is indeed a technically viable alternative with positive outcomes without the need for thoracotomy and sternotomy.

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 it
