Abstract
Background: The feasibility of transcatheter intervention after transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) is important for the lifetime management of aortic stenosis. Methods: A multicenter study was conducted of 4 patient groups: (1) TAVR using SAPIEN 3 at ≤90% implant depth, (2) TAVR using SAPIEN 3 at >90% implant depth, (3) SAVR, and (4) SAVR with aortic root enlargement (ARE) who underwent post-treatment computed tomography. Future TAVR was classified as challenging if the simulated neo-skirt was at or above the coronary ostia and <4 mm away from the coronary ostia and/or <2 mm from the sinotubular junction or aortic wall. Results: < 0.001). Conclusions: Based on post-treatment computed tomography analysis, TAVR with SAPIEN 3 at implant depth ≤90% was the most repeatable initial intervention whereas SAVR with ARE did not improve the feasibility of future TAVR.

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
