Commentary: Robotic totally endoscopic coronary artery bypass: State of an art
Bibliographic record
Abstract
Totally endoscopic coronary artery bypass (TECAB) with robotic assistance can be performed for single left internal thoracic artery–left anterior descending or multivessel grafting, either on the beating or arrested heart, with or without recourse to a small anterolateral thoracotomy. Conventionally, handsewn coronary anastomoses are undertaken via a small left thoracotomy; however, a complete port-based approach can also be used to perform the anastomoses by using endoscopic tools such as nickel-titanium suture clips (U-CLIP; Medtronic Inc, Minneapolis, Minn) or even automated anastomotic devices such as the now-defunct C-Port Flex (Cardica, Redwood City, Calif).
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
