A Concern About 2-Minute Glutaraldehyde-Treated Autologous Pericardium for Mitral Valve Repair
Bibliographic record
Abstract
to assess its durability compared with previous studies.2,4 Freedom from reoperation following MVP using glutaraldehyde-treated autologous pericardium, especially when using a leaflet augmentation technique, gets worse 5 years after MVP for various mitral diseases (96.9±2.2% vs. 93.4±3.2% at 5 years and 89.7±4.5% vs. 68.8±13.7% at 10 years; log-rank, P=0.008).5 Severe calcification of glutaraldehyde-treated autologous pericardium 5 years after MVP for AIE is also reported.6 This pericardium was treated by glutaraldehyde for 15 min.Further follow-up is necessary to confirm the durability of 2-min glutaraldehyde-treated autologous pericardium for MVP.In addition, we need evidence to support the basic stability and strength of 2-min glutaraldehyde-treated autologous pericardium. DisclosuresThere was no conflict of interest in this study.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
