PCI VS CABG for patients with CTO: Contemporary techniques and outcome-single center experience
Bibliographic record
Abstract
CTOs are common findings on coronary arteriograms [1]. CTOs were defined as 100% coronary occlusion present for at least three months and found in almost 20% of all angiograms of patients with angina. The choice of therapy for patients undergoing coronary angiography and found to have CTOs was studied in The Canadian Multicenter Chronic Total Occlusions Registry [2]. Almost half the patients with CTOs were treated medically, and 25% underwent CABG (CTOs bypassed in 88%). PCI was performed in 30%, with a 70% success rate. While more patients with CTOs have historically been treated with CABG than PCI, technical advancements in PCI of CTOs may be expected to drive more patients with CTOs towards being treated with PCI [3].

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.
