Insights
The 6-Fr Glidesheath Slender and standard sheath show similar success rates for transradial coronary angiography. Patient factors influencing procedural failure differ between the two sheath types.
Area of Science:
- Cardiology
- Interventional Cardiology
- Vascular Access
Background:
- Radial artery spasm is a common cause of procedural failure in transradial cardiac catheterization.
- Evaluating alternative sheath designs is crucial for improving procedural outcomes.
Purpose of the Study:
- To compare the procedural success rates of the 6-Fr Glidesheath Slender and a 6-Fr standard sheath.
- To assess the incidence of radial artery spasm with each sheath type during transradial procedures.
Main Methods:
- Prospective enrollment of patients undergoing transradial coronary angiography.
- Comparison of procedural success and spasm rates between the Glidesheath Slender and standard sheath groups.
Main Results:
- No significant difference in procedural failure rates between the Glidesheath Slender (10.5%) and standard sheath (8.9%) groups.
- Higher, though not statistically significant, rates of spasm observed with the Glidesheath Slender (7.9%) versus the standard sheath (5.7%).
- Different patient characteristics influenced procedural outcomes depending on the sheath used.
Conclusions:
- Procedural success rates are comparable between the 6-Fr Glidesheath Slender and standard sheath for transradial access.
- Patient-specific risk factors for procedural failure may vary between the two sheath types.
Background:
The most common cause of procedural failure in cardiac catheterization using the transradial approach is radial artery spasm. The aim of this study was to compare the procedural success rate of the 6‑Fr Glidesheath Slender with the 6‑Fr standard sheath in transradial coronary angiography and intervention.
Methods:
Patients who underwent percutaneous coronary angiography via the transradial approach through placement of a 6-Fr Glidesheath Slender or a 6-Fr standard sheath for primary radial access were prospectively enrolled in the study.
Results:
The study included 200 cases: 76 patients undergoing percutaneous coronary angiography with the Glidesheath Slender and 124 patients with the standard sheath. Failed procedures were recorded for 19 patients (9.5%), defined as inability to complete the procedure via the primary access. There was no difference in the percentage of failed cases between the Glidesheath Slender and standard sheath groups (10.5% vs. 8.9%, OR = 1.21, p = 0.8). More cases of spasm were observed in the Glidesheath Slender group compared with the standard sheath group, which was not statistically significant (7.9% vs. 5.7%, OR = 1.43, p = 0.56). Smoking, hyperlipidemia, and age influenced the procedural outcome in the Glidesheath Slender group, while body mass index, sex, and smoking impacted the procedural outcome in the standard sheath group.
Conclusion:
There is no difference in procedural success rates, as defined by the ability to complete the procedure via primary radial access, between the 6‑Fr Glidesheath Slender and the 6‑Fr standard sheath. Our study suggests that the patient characteristics that elevate the risk of procedural failure for Glidesheath Slender may differ from those for the standard sheath.
