Combined Transmyocardial Laser Revascularization with Off-Pump Coronary Artery Bypass Grafting in Management of Patients with Severe Isehemic Heart Disease
Bibliographic record
Abstract
Objectives To assess the safety and effecacy of combining transmyocardial laser revascularization (TMLR) with off-pump coronary artery bypass grafting (OPCAB) in patients, who were not amenable to complete revascularization by coronary artery bypass alone. Methods From October 1999 to June 2002, 10 patients whose standand of care were off-pump coronary artery bypass grafting and who had one or more nongraftable areas which were treated with Holmium YAG laser transmyocardial revasculariaztion as an adjunt. Results The mean number of vessels bypassed was 2.6±4 and the mean number of laser channels was 19.5±9. All patients were uneventful in the early postoperative period. Mean follow-up was 18.1±5 months. At this time, all patients were alive and had good quality of life. Mean CCS angina class decreased significantly from the baseline of 3.2±0.8 to 0.2±0.4(P 0.000 1), with 8 patients angina free. Non-patient had to use nitrates or readmit for cardiac events after operation. Mean resting left ventricular EF increased from baseline of 53.2% to 65.4% at follow-up, and left ventricular wall motion score was improved. Conclusions TMLR combined with OPCAB is a safe and effective surgical procedure to achieve complete myocardial revascularization in severe coronary artery disease patients with some ungraftable areas. As the long-term symptomatic benefits of sole TMLR is still uncertain, except in special conditions, it is best used as an adjunct to CABG.

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.
