Abstract

fetched live from OpenAlex

The abnormal accumulation of lipid-rich adipose tissue within the interatrial septum (IAS) is the hallmark of lipomatous hypertrophy of the interatrial septum (LHIS), a relatively rare medical condition. To accurately distinguish LHIS, it is essential to recognize the characteristic "dumbbell" shape of IAS. Here, we present a case of a 59-year-old woman who was suspected of having cardiac myxoma and was subsequently admitted to our hospital. Transthoracic echocardiography of the patient showed that the IAS had a lack of thickening in the region of the foramen ovale and a hyperechogenic structure in the basal and vault portions of IAS. An abnormal mass located in the IAS anterior to the foramen ovale and not infiltrating the foramen ovale was discovered by computed tomography (CT) scan of the heart. The cardiac magnetic resonance imaging (MRI) confirmed the presence of significant fat deposition within the IAS with sparing of the fossa ovalis, which was consistent with the initial findings. The patient was discharged home with the recommendation of regular visits to the cardiology outpatient clinic for LHIS monitoring. The article presents the visualization of LHIS in consecutive diagnostic modalities, summarizes the actual knowledge of LHIS, and enables proper LHIS diagnosis in patients based on available imaging methods.

Not 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.
