A case of crowded heart: closing the door after the visitors
Bibliographic record
Abstract
A 79-year-old woman was admitted to the cardiology department for right heart failure (RHF). This patient had undergone a recent intervention consisting of transcatheter aortic valve implantation (TAVI) with an EvolutR 23 mm (arrow, Panel A), transcatheter mitral valve implantation (TMVI) with a S3 Ultra 23 mm (arrowhead, Panel A) and left atrial appendage occlusion with an Amplatzer Amulet 18 mm (*, Panel A) for degenerated aortic and mitral bioprotheses and recurrent anaemia due to angiodysplasia. An expected iatrogenic atrial septal defect (ASD) with left-right shunt was noted on post-procedural echocardiography. Thereafter, the patient developed clinical and echographic signs of right heart failure leading to an invasive evaluation in the cathlab. An occluding balloon (Panel B) was positioned across the ASD and confirmed non-significant elevation of the transmitral gradient (From 7.9 to 8.7 mmHG, Panel C) along with reduction of the V wave in the right atrium (from 22 to 17 mmHG, Panel D). A 20-mm Amplatzer ASD occluder (°, Panel A) was successfully deployed. The patient evolved well and control transoesophageal echocardiography showed an absence of residual shunt and functional TAVI, TMVI and Amulet prostheses.

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.
