Mechanical Circulatory Support for Peripartum Cardiomyopathy
Bibliographic record
Abstract
Peripartum cardiomyopathy (PPCM) is a rare cause of heart failure that occurs late in pregnancy or during the early postpartum period. Left ventricular assist devices (LVADs) are a form of mechanical circulatory support that are most often implanted for the management of advanced heart failure. We describe a case of PPCM that we managed through implantation of an LVAD with the hope of allowing for myocardial recovery. A 38-year-old female presented 10 days postpartum with chest pain, shortness of breath and hypotension. An echocardiogram revealed a left ventricular ejection fraction (LVEF) of 25%. The patient received an LVAD. Her hemodynamics and symptoms improved dramatically following implantation, and her postoperative course was uncomplicated.

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.
