Abstract
The CoreValve Evolut R with EnVeo R delivery catheter is a novel transcatheter heart valve (THV) system with enhanced features that have the potential to improve the safety of transcatheter aortic valve implantation (TAVI). The newly designed delivery catheter is 14 Fr-equivalent and thus expands the option of transfemoral TAVI to a greater proportion of patients. Most importantly, the EnVeo R delivery catheter allows the valve to be recaptured and repositioned during deployment, thus minimising the consequences of THV malposition. Furthermore, the nitinol frame of the CoreValve Evolut R has been redesigned for superior interaction, consistent radial force and optimised cover index across the sizing range, and conformability with the native annulus, thereby hypothetically reducing stress on the left bundle branch. Although large series with long-term follow-up are required to demonstrate the safety and efficacy of this device, we present the first human experience with the Evolut R system.

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
