Cage‐Free Chronic Occlusion PCI: Multivessel Total and Subtotal Occlusion Treatment With Drug Coated Balloon Angioplasty
Bibliographic record
Abstract
Drug-coated balloon (DCB) catheters offer an alternative to drug-eluting stents (DES) by delivering anti-proliferative drugs directly to vessel walls, avoiding implantation of a permanent metallic structure. While DCBs have shown efficacy for in-stent restenosis, evidence for their application in de novo coronary disease and chronic total occlusion (CTO) PCI is growing. We present a case of a 49-year-old male with multivessel chronic total and subtotal occlusions who had complete percutaneous revascularisation using a DCB only strategy. Each lesion had unique characteristics involving its length and location, bifurcation anatomy, and vessel diameter for which this stent-free approach was favored. DCB use in CTO PCI may be promising in select cases and lesions, and further studies are warranted to ascertain long-term efficacy in this setting.

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.
