Case report of isolated aortic valve AL-amyloidosis following aortic valve replacement
Bibliographic record
Abstract
Background: Light chain (AL)-amyloidosis is a haematologic malignancy where cardiac involvement confers a worse prognosis. There is a recognized association between aortic stenosis (AS) and transthyretin amyloidosis (ATTR) cardiomyopathy. However, there is no such reported association with AL amyloidosis. Case summary: We present a case of degenerative AS where the pathology analysis post-surgical replacement demonstrated amyloid deposits subsequently identified as AL subtype by mass spectrometry. Subsequent investigations demonstrated no myocardial or systemic involvement. Following multidisciplinary discussion, cardiac biopsy and chemotherapy were deferred given the isolated nature of aortic valve involvement and clinical stability. Discussion: Incidental detection of aortic valve AL-amyloidosis in this case demonstrates that such deposits cannot be assumed to be ATTR, and further work-up and amyloid typing is necessary.

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.
