Relapsing Mitral Involvement in Antineutrophil Cytoplasmic Antibody–Associated Vasculitis
Bibliographic record
Abstract
Cardiac valvular involvement in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis is very rare. We report the case of a patient seen in 2019, followed for ANCA-associated vasculitis for 15 years, who had a first relapse with cardiac valvular involvement in 2012, and who underwent a second histologically proven vasculitis relapse involving mitral periprosthetic endocardium. PET/CT imaging showed an intense and focal FDG activity of paramitral bioprosthesis leak site. Mitral bioprosthesis was replaced, and the patient improved with steroids and rituximab. Through this exceptional case, we suggest that FDG PET/CT could be of interest in the follow-up of ANCA-associated vasculitis with cardiac valvular involvement.

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.
