Radial artery conduit for coronary revascularization: as good as an internal thoracic artery?
Bibliographic record
Abstract
PURPOSE OF REVIEW: Multiple arterial grafting has been proposed to improve outcomes after coronary bypass surgery. We sought to define the emerging role of the radial artery as an alternative second arterial graft. RECENT FINDINGS: Despite significant evidence suggesting superiority of bilateral internal thoracic artery grafting, utilization in current clinical practice remains low due to concerns about sternal wound infection and conduit length. Recent clinical trials have started to clarify the role of the radial artery in coronary surgery. This conduit provides superior patency to saphenous vein grafts in the setting of high-grade stenosis regardless of the target territory and with minimal harvest site complications. SUMMARY: The radial artery is a versatile conduit that provides clinical benefit in a large variety of patients undergoing coronary bypass surgery. Outcomes from ongoing longitudinal clinical trials will further clarify optimal conduit selection strategies.

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.
