eComment. Marginal hearts: a second-round draft picks?
Bibliographic record
Abstract
We read with interest the article by Pinto and his colleagues, who describe a case report of coronary artery bypass grafting surgery (CABG) in a transplanted heart [1]. With increased longevity in Western countries, the number of patients with end stage heart disease is increasing and studies have reported that advanced age should not be a contraindication for heart transplantation [2]. On the other hand, this philosophical change will add to the recognized gap between available donors and recipients for heart transplantation. The use of marginal donors is therefore a potential strategy to increase donor recruitment and indeed the use of this strategy has been successful in high volume transplant centers [3–5]. We recently encountered a critical clinical situation, in which a marginal donor with significant coronary artery disease was accepted for a recipient who was in cardiogenic shock despite of maximal medical and mechanical support. A 74-year old man presented with ischaemic cardiomypathy with an ejection fraction of 13%. He had a positron emssion tomohgraphy (PET) scan, which demonstrated that he had viable hibernating myocardium in a large portion of his anterior wall, suggest-

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.
