Abstract
Abstract Background Acute coronary syndrome is a rare complication of infectious endocarditis. We present the case of a patient with a bicuspid aortic valve who presented an acute ST elevation myocardial infarction (STEMI) of the inferior wall secondary to vegetation that generated obstruction of the ostium of the right coronary artery (RCA). Case summary A 54-year-old patient with only a history of smoking was admitted for chest pain. An acute STEMI in the inferior wall was documented; he underwent an emergent coronary angiography, which showed a mass that obstructed the ostium of the RCA that did not allow its channelling. An angiotomography of the aorta was performed, where dissection was ruled out and the presence of a mass in the right coronary sinus that protruded towards the ostium of the coronary artery was confirmed. In the extension studies, a bicuspid aortic valve and thrombosis in the right brachial artery and in the infrarenal abdominal aorta were documented. Discussion The case was taken to a medical meeting and given the embolic and mechanical compromise; it was decided to perform surgery where a mass that invaded the proximal segment of the RCA was resected. The histopathological study documented findings of vegetation; the cultures were positive for Staphylococcus epidermidis, and he finally received antibiotic and anticoagulation treatment.

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
