First Transcatheter Valve-in-Valve Implantation With Myval Octacor Into a Failed Biological Prosthetic Aortic Valve in Serbia
Bibliographic record
Abstract
The natural progression of bioprosthetic valve degeneration over time requires further interventions for those experiencing symptomatic prosthesis dysfunction. Transcatheter aortic valve replacement (TAVR) emerges as a promising therapeutic option to alleviate symptoms in such patients. The valve-in-valve (ViV) technique eliminates the necessity for repetitive open-heart surgical procedures, offering particular advantages for individuals with higher surgical risks. In this report, we describe the case of a 78-year-old female patient presenting with severe symptomatic aortic restenosis of a biological aortic valve implanted 5 years prior. Given the patient's high surgical risk, a transcatheter ViV implantation was chosen as the treatment approach. Utilizing a balloon-expandable valve, the intervention resulted in the successful implantation of a functional TAVR, resulting in symptom relief and enabling a fast discharge from the hospital.

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.
