Edwards SAPIEN™ and Edwards SAPIEN XT™ transcatheter heart valves for the treatment of severe aortic stenosis
Bibliographic record
Abstract
Aortic stenosis is the most common heart valve lesion, with aortic valve replacement being the most common type of valve surgery in the Western world. With the aging population, more and more patients are declined for surgical aortic valve replacement owing to age and comorbidities. Without intervention, morbidity is significant and early mortality inevitable. Transcatheter aortic valve replacement is an exciting technology offering an alternative, less invasive treatment in those not eligible for surgery. The Edwards SAPIEN and Edwards SAPIEN XT transcatheter heart valves are currently in widespread use, with promising outcomes in terms of short-to-medium-term mortality and valve durability in high-risk patients or patients not eligible for surgical valve replacement. Randomized trials are currently underway to assess transcatheter aortic valve replacement in lower risk surgical candidates, while long-term mortality data are keenly awaited.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
