Abstract

fetched live from OpenAlex

BE-THV are traditionally positioned and deployed in coplanar projection, with RCC projected between the NCC and LCC. Ostium of LM is usually not visualized in this projection. If outflow of THV is positioned above LM ostium this may pose challenges for future redo THV procedures. We sought to investigate whether implantation using LM-View for TAVR with BE-THV can result in a safe and reproducible implantation and play a role in facilitating lifetime management for AS.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
