Efficacy of a one-catheter concept for transradial coronary angiography.

Introduction: Transradial coronary angiography (TRC) can be performed with a one-catheter approach for the right and left coronary ostium (R/LCO). We investigated the performance of a special diagnostic catheter widely used for the one-catheter-approach, the Tiger (Tiger II, TerumoTM).

Methods: In a dual center registry we analyzed 1412 TRC-procedures exclusively performed by experienced TRC-operators.

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

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.
