title: Transradial Coronary Angiography--Insights to the One-Catheter Concept.
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.
