Coronary angiography (CAG) and possible angioplasty (Percutaneous Coronary Intervention =
PCI) can be performed by access from the groin (a. femoralis), the wrist (a. radialis) or the
elbow (a. brachialis). It is well established that there is less risk of bleeding
complications when using a radial access. The smaller diameters of the vessels in the
forearm, however, may result in increased risk of pain during CAG/PCI via a. radialis. This
is associated with vascular spasm (spasm tendency). Ultimately this means that one may have
to convert to access via a. femoralis.
To perform a CAG/PCI, a tube (a so-called sheath) has to be inserted in a. radialis. It is
unclear whether the design of the sheaths can reduce the spasm tendency, thus reducing pain.
Terumo has recently introduced a new kind of sheath, so-called Terumo Glide Slender Heath
Coated (hereafter referred to as "Slender sheath"). This sheath is partly coated, partly made
of a thinner material. "Slender sheath" thus has an outer diameter smaller than that of the
sheath from traditional use (Terumo Radio Focus sheath, hereafter referred to as "Standard
sheath"), although the inner diameter (lumen) is the same in the two sheaths. In turn, the
"Slender sheath" is more fragile and far more expensive.
The purpose of the present study is to evaluate whether use of slender sheath compared with
standard sheath is Associated with less pain and fewer complications following CAG/PCI.
