Cardiac Observations Late After Operative Transmyocardial Laser “Revascularization”
Bibliographic record
Abstract
This chapter presents a case study of a 60-year-old man, had an acute myocardial infarction at age 39 years and underwent coronary artery bypass grafting at that time. He apparently did well thereafter until age 52 when angina pectoris appeared. A second coronary bypass was performed at that time and he became asymptomatic until age 59 when angina reappeared. The angina rapidly worsened to Canadian Cardiovascular Society class IV despite anti-anginal drug therapy. Cardiac catheterization showed total occlusions of the aortocoronary saphenous venous conduits to the left obtuse marginal and right coronary arteries and a patent left internal mammary artery to a diffusely and severely narrowed native left anterior descending coronary artery. Small fixed anterior wall and moderate-sized reversible inferolateral wall perfusion defects were seen by dual-isotope, single-photon emission computed tomography perfusion scanning. The left ventricular cavity was mildly dilated, the lateral and anterior walls were hypokinetic, and ejection fraction was 44%.

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.
