Use of Different Diagnostic Coronary Catheters Over the Radial Access - the UDDC - Radial Trial

The aim of the present trial is to evaluate the efficacy and safety of a one-catheter concept using the BLK (Terumo, Somerset, USA) or the Tiger catheter (Terumo, Somerset, USA) compared to the standard Judkins catheters in diagnostic coronary angiography by the transradial access. Patients with stable angina pectoris will be randomly assigned to coronary angiography performed with the BLK (Group I), Tiger (Group II) or Judkins catheters (Group III). Primary endpoint is the time duration (sec) that is necessary to perform complete coronary angiography including 6 different projections for the left-coronary system and 3 different projections of the right-coronary-system. Secondary endpoints will cover safety and imaging quality of the different catheter systems.
