THE FEASIBILITY OF PERCUTANEOUS TRANSRADIAL CORONARY INTERVENTION FOR CHRONIC TOTAL OCCLUSION (CTO)
Bibliographic record
Abstract
Objectives To evaluate the feasibility and effect of the radial approach in chronic total occlusion (CTO) percutaneous coronary intervention. Methods 80 patients, 37 of which were remote myocardial infarction, 38 unstable angina, five chronic stable angina, were accepted angiography via radial access. Angiography revealed there were 45 patients with three-vessel disease, 19 two-vessel disease, 16 single vessel disease and 48 patients with left anterior descending artery CTO, 15 left circumflex artery, 17 right coronary artery. Guidewires of CrosswireNT, Miracal3, 4.5, 6, 9, 12, conquest 9, 12 (PRO) were used in percutaneous transradial coronary intervention for chronic total occlusion. Results The success rate of transradial PCI was 80%(64 of 80 cases), with 145 stents implanted, and the causes of failure included failure to pass the guidewire through the lesion in nine of 16 failure cases, failure of balloon passage in seven cases, failure of cardiac tamponade in no case. Conclusions the radial artery might be a feasible vascular route in coronary interventions for CTO, with comparable procedural success and no access site complications.

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.
