About this study
Official title: Safety and Efficacy of 6-French Glidesheath Slender in Coronary Angiography and Percutaneous Coronary Intervention Via Distal Transradial Access in Patients With Small Vessels: A Single-Center, Adaptive, Randomized Controlled Study
Randomized controlled trial of adaptive design for the safety and efficacy of coronary angiography and percutaneous coronary intervention via distal transradial access using a 6-French Glidesheath Slender in patients with small vessels.
Read the detailed description
The safety and efficacy of coronary angiography and percutaneous coronary intervention via distal transradial access (dTRA) have been confirmed by a large number of studies, but there are still few studies on its safety and efficacy in patients with small vessels (distal radial artery diameter < 2.0mm). The 6-French Glidesheath Slender, with its smaller outer diameter, should be more suitable for patients with small vessels. To this end, we plan to conduct a single-center, adaptive, randomized controlled trial enrolling 594 patients aged 18-85 years old with distal radial artery diameters <2.0 mm and ≥1.0 mm who are scheduled to undergo coronary angiography and percutaneous coronary intervention via the distal radial artery approach in our center. The study employed a stratification-block randomized design. Stratification was performed based on patient gender, with a block size of 4 within each stratum. Eligible patients were randomly assigned in a 1:1 ratio to either the 6-French Glidesheath Slender group or the 6-French conventional sheath group.
The primary endpoint of the study was distal radial artery occlusion assessed by vascular ultrasound 24 hours postoperatively. Secondary endpoints included puncture success rate, procedure success rate, number of punctures, puncture time, total procedural time, visual analogue scale pain scores during sheath placement, bleeding, hematoma, arteriovenous fistula, finger numbness, and conventional radial artery occlusion at 24 hours postoperatively.
An interim analysis will be conducted when 50% of the total sample size (297 patients) is enrolled, with subsequent sample size adjustments based on preliminary study results.
The results of this study will provide evidence for the safety and efficacy of 6-French Glidesheath Slender for coronary angiography and percutaneous coronary intervention in patients with small vessels via distal transradial access, and provide information for the selection of the best sheath equipment for patients with small vessels.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Randomized controlled trial of adaptive design for the safety and efficacy of coronary angiography and percutaneous coronary intervention via distal transradial access using a 6-French Glidesheath Slender in patients with small vessels.
Detailed description
The safety and efficacy of coronary angiography and percutaneous coronary intervention via distal transradial access (dTRA) have been confirmed by a large number of studies, but there are still few studies on its safety and efficacy in patients with small vessels (distal radial artery diameter < 2.0mm). The 6-French Glidesheath Slender, with its smaller outer diameter, should be more suitable for patients with small vessels. To this end, we plan to conduct a single-center, adaptive, randomized controlled trial enrolling 594 patients aged 18-85 years old with distal radial artery diameters <2.0 mm and ≥1.0 mm who are scheduled to undergo coronary angiography and percutaneous coronary intervention via the distal radial artery approach in our center. The study employed a stratification-block randomized design. Stratification was performed based on patient gender, with a block size of 4 within each stratum. Eligible patients were randomly assigned in a 1:1 ratio to either the 6-French Glidesheath Slender group or the 6-French conventional sheath group.
The primary endpoint of the study was distal radial artery occlusion assessed by vascular ultrasound 24 hours postoperatively. Secondary endpoints included puncture success rate, procedure success rate, number of punctures, puncture time, total procedural time, visual analogue scale pain scores during sheath placement, bleeding, hematoma, arteriovenous fistula, finger numbness, and conventional radial artery occlusion at 24 hours postoperatively.
An interim analysis will be conducted when 50% of the total sample size (297 patients) is enrolled, with subsequent sample size adjustments based on preliminary study results.
The results of this study will provide evidence for the safety and efficacy of 6-French Glidesheath Slender for coronary angiography and percutaneous coronary intervention in patients with small vessels via distal transradial access, and provide information for the selection of the best sheath equipment for patients with small vessels.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 19 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact gaojun GJ cai, PhD (+86 0519-85579192, caigaojun@wjrmyy.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
