Rheumatic mitral valve disease in pregnancy
Bibliographic record
Abstract
A 32-year-old Nepalese woman with known rheumatic mitral valve disease presented 17 weeks into her first pregnancy with exertional breathlessness and wheezing, leading to expectoration of foamy pink liquid. Her history included percutaneous balloon mitral valvotomy at the age of 25 years, after which she had remained asymptomatic and fully active. She had three episodes of acute pulmonary oedema and was transferred to a tertiary centre for further management. An echocardiogram suggested severe mitral stenosis (mitral valve area 1.0 cm 2 ) and pulmonary hypertension (mean pulmonary artery pressure 87 mmHg). She had further episodes of pulmonary oedema despite maximal medical therapy with diuretics, cardioselective beta blockers (dose limited because of systolic hypotension), digoxin, nitrates and anticoagulation. At 21 weeks' gestation, an emergency St Jude metallic valve was implanted. Unfortunately, intrauterine death occurred 2 days postoperatively, likely caused by pre-eclampsia or haemolysis, elevated liver enzymes and low platelets (HELLP) syndrome. The patient recovered well and continues on warfarin and a small dose of beta blocker.

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.
