Abstract

fetched live from OpenAlex

Cerebrovascular accidents (CVA), mainly stroke, are still one of the Achilles’ Heels of transcatheter aortic valve implantation (TAVI) procedures; however, clinically evident strokes are not the only concern. TAVI procedures have also been associated with covert cerebral emboli captured on transcranial Doppler as high-intensity transient signals (HITS) and ultimately defined as silent brain infarcts, as documented on diffusion-weighted imaging magnetic resonance imaging (DWI-MRI)1,2. Notably, the incidence of silent brain infarcts is very much higher (up to 90%)1 than that of clinically evident strokes, which ranges from 0%3 to 2.3-2.5% at 30 days4. The risk of periprocedural cerebrovascular complications in patients ...

Full frame distilled prediction

Teacher imitation

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.
