Multiarterial coronary artery bypass grafting
Bibliographic record
Abstract
PURPOSE OF REVIEW: The debate on the second best conduit for CABG is still intense. In this review, we discuss the role of the radial artery and the right internal thoracic artery (RITA) compared with saphenous vein grafts (SVG). RECENT FINDINGS: The recent RADIAL STUDY has been the first evidence based on randomized trials of a clinical benefit using a second arterial graft in CABG.On the other hand, the definitive 10-year results of the ART trial failed to show a clinical advantage associated with the use of bilateral internal thoracic artery (BITA). A thorough and contextualized analysis of this and other studies, however, may offer a different perspective. SUMMARY: Arterial conduits in CABG have shown better patency rates than SVG. Whether this leads to better clinical outcomes is still debated. In this setting, the radial artery and the RITA seem to offer a similar advantage, although with different indications and contraindications.

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.
