Constrictive Pericarditis: Rapid Progression of Pericardial Calcification in a Patient With Hemodialysis and Coronary Artery Bypass Surgery
Bibliographic record
Abstract
A 72-year-old man, with a history of coronary artery bypass grafting (CABG) undergone19 years previously and end-stage renal disease (ESRD) on hemodialysis since 1 year before, was admitted for evaluation of dropping arterial pressure down 1 hour after starting hemodialysis. On a computed tomography on chest scan, markedly calcified pericardium on the posterior and diaphragmatic sides of the heart was revealed. Pericardium was mostly not calcified 2 years before admission, pre-initiation of hemodialysis, and the thickness of calcified pericardium was obviously increased after initiation of hemodialysis. Constrictive pericarditis (CP) was diagnosed and subsequent pericardiectomy was underwent, and dropping atrial pressure down during hemodialysis disappeared. The main cause of CP was not cardiac surgery undergone previously (postoperative CP). It is probable that secondary hyperparathyroidism in ESRD provoked dystrophic calcification of pericardium, which was injured by past CABG, subsequent rigid and thickness of pericardium, and constrictive physiology became obvious.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
