Endoscopic Conduit Harvest in Coronary Artery Bypass Grafting Surgery
Bibliographic record
Abstract
OBJECTIVE: The purpose of this consensus conference was to develop and update evidence-informed consensus statements and recommendations on harvesting saphenous vein and radial artery via an open as compared with endoscopic technique by systematically reviewing and performing a meta-analysis of randomized and nonrandomized clinical trials. METHODS: All randomized controlled trials and nonrandomized controlled trials included in the first the International Society for Minimally Invasive Cardiothoracic Surgery Consensus Conference and Statements, in 2005 up to November 30, 2015, were included in a systematic review and meta-analysis. Based on the resultant, 76 studies (23 randomized controlled trials and 53 nonrandomized controlled trials) on 281,459 patients analyzed, consensus statements, and recommendations were generated comparing the risks and benefits of endoscopic versus open conduit harvesting for patients undergoing coronary artery bypass grafting. RESULTS: Compared with open vein harvest, it is reasonable to perform endoscopic vein harvest of saphenous vein to reduce wound-related complications, postoperative length of stay, and outpatient wound management resources and to increase patient satisfaction (class I, level A). Based on the quality of the conduit and major adverse cardiac events as well as 6-month angiographic patency, endoscopic vein harvest was noninferior to open harvest. It is reasonable to perform endoscopic radial artery harvest to reduce wound-related complication and to increase patient satisfaction (class I, level B-R and B-NR, respectively) with reduction in major adverse cardiac events and noninferior patency rate at 1 and 3 to 5 years (class III, level B-R). CONCLUSIONS: Based on the consensus statements, the consensus panel recommends (class I, level B) that endoscopic saphenous vein and radial artery harvesting should be the standard of care for patients who require these conduits for coronary revascularization.

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.
