Abstract
Objective To summarize the early outcomes and clinical experience of off-pump coronary artery bypass grafting (off-pump CABG) after off-pump coronary endarterectomy (CE) for patients with diffused coronary artery disease. Methods From May 2003 to November 2006,83 patients with diffused coronary artery disease underwent CE without cardiopulmonary bypass and off-pump CABG. There were 61 males and 22 females with age ranged from 55 to 80 years (65±7 years). There were 7 patients in Canadian Cardiac Society(CCS) angina classⅡ,20 patients in class Ⅲ,and 56 patients in class Ⅳ. 36(43.4%) patients had history of myocardial infarction. Coronary angiogram revealed that 5 patients had double vessels disease, and other 78 patients had triple vessels disease with 16 left main stem disease. The left ventricular ejection fraction(LVEF) ranged from 25% to 65% (51%±16%). One hundred and ten endarterectomies were performed in 83 patients totally which included 67 in left anterior descending artery(LAD),9 in circumflex artery and 34 in right coronary artery. Twenty patients received on-lay venous patch after CE in LAD and then grafted by internal mammary artery (IMA) on the patch. There were 83 left IMA, 2 radial arteries, others were great saphenous veins, the mean number of grafts was 3.9±1.2. Results There was no death in all patients. Intra-operative graft flow-meter was used to check the flow in the grafts before chest closure. One hundred and one (92%) out of 110 grafts after CE showed a satisfactory grafts flow(22±16ml/min) intraoperatively. Four patients had perioperative myocardial infarctions but none had hemodynamic changes. All patients discharged uneventfully. Seventy-five patients (90.4%) had 8 to 50 months follow-up with no angina re-occurrence. Eight patients had coronary angiogram from 3 to 29 months after operation with all patent grafts to the CE coronaries. Conclusion Off-pump CABG with coronary endarterectomy is feasible and achieves surgical revascularization in patients with diffuse coronary artery disease.

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.
