| Abstract: | Transradial coronary angiography (TRC) can be performed applying only one catheter fitting into the right and left coronary ostia (R/LCO). In this bicentric study (n = 2953), we analyzed the ostial performance of the Tiger_II_catheter widely used in TRC. Compared to Judkins catheters, the Tiger_II is frequently associated with ostial instability within the LCO but fits better into the RCO—irrespective of tube size. Judkins catheters generally need more peri‐procedural contrast and radiation exposure. TRC may be started using a 5F_Tiger_II on the right side in order to be switched to 5F Judkins in case of propable LCO instability. (J Interven Cardiol 2016;29:113–116) |
