Long-Term Prognosis in Patients Undergoing Redo-Isolated Aortic Valve Replacement
Bibliographic record
Abstract
Aim: To evaluate clinical outcomes after redo aortic valve replacement (AVR) with sutured valves, versus valve-in-valve transcatheter aortic valve replacement (ViV-TAVR), versus sutureless valves. Methods: We identified 113 consecutive patients undergoing redo AVR with either ViV-TAVR, redo-sutured and redo-sutureless valves between August 2010 to March 2020. Heart-team made the decision whether patient should undergo redo-sutureless versus ViV-TAVR, versus redo-sutured AVR. Results: Preoperatively, redo-sutured (n = 57), ViV-TAVR (n = 31) and redo-sutureless (n = 25) patients were compared. Postoperatively, after propensity-adjustment analysis, the redo surgical aortic valve replacement group had a higher incidence of new postoperative atrial fibrillation (POAF; p = 0.04) compared with redo-sutureless group. Follow-up outcomes analysis did not show differences among groups. Conclusion: Patients undergoing redo-sutureless AVR experienced a higher incidence of POAF compared with patients undergoing redo-sutured.

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.
