HD-IVUS-Guided Tip Detection–Antegrade Dissection and Re-Entry (TD-ADR)
Bibliographic record
Abstract
We present a clinical case highlighting high-definition intravascular ultrasound (HD-IVUS)-guided tip detection-antegrade dissection and re-entry (ADR). This novel technique in percutaneous coronary intervention of chronic total occlusions was pioneered in Japan using a specially designed intravascular ultrasound catheter (AnteOwl WR IVUS, Terumo) and was replicated in this case using off-the-shelf equipment after antegrade and retrograde attempts with conventional methods were unsuccessful. To the best of our knowledge, this marks the first successful tip detection-ADR procedure performed using commercially available equipment in North America. Our experience shows that imaging-guided ADR can be a potentially helpful adjunctive strategy for challenging chronic total occlusion percutaneous coronary intervention.

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.
