Gender-Specific Performance of One- Compared to Two-Catheter Concepts in Transradial Coronary Angiography - Insights From the Randomized UDDC-Radial-Trial.

Objectives: The present sub-analysis from the randomized UDDC-Radial-Trial sought to compare one-catheter concepts (OCC) with two-catheter concepts (TCC) in different patient subgroups, particularly in those depending on gender and age.

Background: There is an ongoing debate regarding potential performance differences of OCC compared to TCC for transradial coronary angiography in specific patient subgroups.

Methods: The randomized UDDC-Radial-Trial enrolled a total of 300 patients planed for coronary angiography in a 2:1 ratio to either OCC by Tiger II (n = 100) and BLK (n = 100) or TCC by Judkins (n = 100) catheters.
