Abstract

Aims: The 6 Fr Glidesheath Slender (GSS6Fr) is a recently developed thin-walled radial sheath with an outer diameter (OD) that is smaller than the OD of standard 6 Fr sheaths. The purpose of this trial was to clarify whether the use of this new slender sheath would result in similar rates of RAO to a standard 5 Fr sheath in unselected patients undergoing transradial (TR) coronary angiography and/or intervention, and to assess the relative importance of sheath size and haemostasis protocol on the rate of RAO. Methods and results: We conducted a randomised, multicentre, non-inferiority trial comparing the GSS6Fr against the standard GS5Fr in patients undergoing TR coronary angiography and/or intervention. Patients in each group were subsequently randomised to undergo patent haemostasis or the institutional haemostasis protocol. The primary endpoint was the occurrence of RAO at discharge. A total of 1,926 patients were randomised in 12 centres. The incidence of RAO was 3.47% with GSS6Fr compared with 1.74% with GS5Fr (risk difference 1.73%, 95% CI: 0.51-2.95%; pnon-inferiority=0.150). Patients randomised to patent haemostasis had a similar rate of RAO compared with institutional haemostasis (2.61% vs. 2.61%, p=1). There was no difference with regard to all secondary endpoints, including vascular access-site complications, local bleeding and spasm. Conclusions: In this large multicentre randomised trial, the GSS6Fr was associated with a low event rate for the primary endpoint (RAO), although non-inferiority to the GS5Fr was not met, due to a lower than expected rate of RAO in the GS5Fr group. As compared to institutional haemostasis, the use of patent haemostasis was not associated with a reduced rate of RAO.
