Comparison of the Effect of a 6-French Glidesheath Slender and a Conventional Sheath on Distal Radial Artery Occlusion: A Randomized Controlled Trial
Bibliographic record
Abstract
BACKGROUND: There is a lack of randomized clinical trials on whether the 6-French (Fr) Glidesheath Slender (GSS; Terumo, Tokyo, Japan) is superior to the 6-Fr conventional radial sheath (CS) with respect to the early-term incidence of distal radial artery occlusion (dRAO) in patients who have undergone coronary angiography (CAG) and/or percutaneous coronary intervention (PCI) via distal transradial access. METHODS: This was a prospective, single-centre trial of patients who were randomized to undergo CAG and/or PCI with either a 6-Fr GSS or a 6-Fr CS. The primary end point was the incidence of dRAO at 24 hours postoperatively, evaluated using Doppler ultrasound. RESULTS: A total of 620 patients were included in the study. The baseline patient and procedural characteristics were similar among the 2 groups. For the primary end point, the incidence of dRAO at 24 hours after the procedure was 1.0% (3/314) in the GSS group and 3.6% (11/306) in the CS group (risk ratio, 0.266; 95% confidence interval, 0.075-0.943; P = 0.027) according to the intention to treat analysis. For the secondary end points, the incidence of proximal radial artery occlusion was 0.3% (1/314) in the GSS group and 2.3% (7/306) in the CS group (P = 0.029). Other secondary end points, including the puncture success rate, procedural outcomes, other puncture-related outcomes, and access-related complications were not significantly different in the 2 groups. CONCLUSIONS: The use of a thin-walled and hydrophilic coating sheath can reduce the incidence of early-term dRAO in patients who undergo CAG and/or PCI via the distal transradial access. CLINICAL TRIAL REGISTRATION: NCT05501925.

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.
