Abstract
Following the introduction of transcatheter aortic valve im-plantation (TAVI), it is now possible to treat elderly patients with severe aortic stenosis and a high surgical risk. This advancement in interventional cardiology has led to increased survival, health status and quality of life. However, as with many invasive interventional procedures, TAVI is associated with the risk of cerebral embolisation and consequent ischae-mic cerebrovascular events with possible neurological impair-ment. The risk estimates of post-procedural stroke associated with TAVI vary from 1.5 to 10 % and have been reported both early and late after the procedure. In the PARTNER Cohort B study, the Canadian multicentre TAVI registry and the study by Nuis et al., about 50 % of the stroke events occurred more than 24 h post-procedure [1]. In addition to clinically overt stroke, asymptomatic silent cerebral infarcts have been fre-
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 machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
