Current and future transcatheter aortic valve replacement valves
Bibliographic record
Abstract
PURPOSE OF REVIEW: This review analyzes currently available commercial transcatheter aortic valve replacement (TAVR) valves as well as valves in investigational status and those in preclinical testing. The design features and clinical outcomes of the Edwards SAPIEN S3 and Medtronic Evolut PRO+ are described and compared with highlight clinical circumstances where one may be favoured over the other. RECENT FINDINGS: Multiple randomized and nonrandomized trials have compared commercial and investigational TAVR valves. The results of these are summarized and discussed within this review with a focus on how the SAPIEN S3 and Evolut PRO+ both compare to each other as well as various valves in different investigational stages. SUMMARY: TAVR is an innovative and ground-breaking technology that will forever have revolutionized the management of aortic stenosis. Though the technology and valves themselves have come a long way, further developments are necessary if we are to continue to expand its indications and achieve a safer perioperative experience with more durable valves.

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.
