Effectiveness of the TIger Catheter as a simple multipurpose in 
transradial coronary angiography: randomized compared to 
JudKins cathETers. (TICKET) 
 
Introduction. In recent decades transradial coronary angiography has gained popularity 
because of its low frequency of complications. And for this reason, a multipurpose 
catheter has been designed appropriate for the study or both coronaries, the experience 
being this limited field. 
Objectives. The aim of this study was to assess effectiveness and safety of Tiger vs. 
Judkins catheters, in coronary angiography via the right transradial approach. 
Methods. Patients with diagnosis of acute coronary syndrome undergoing transradial 
coronary angiography were randomized into the Tiger catheter vs Judkins catheter. A 
positive Allen´s test was required.  
Primary outcome measures:  Produce time for the coronary angiography.  
 
 
Secundary outcome measures: Fluoroscopy time, Contrast volume used, Radial artery 
spasm. 
Results. Analyzed a total of 120 consecutive diagnostic coronary angiography cases 
from the right radial approach. Of these 60 cases were performed with single catheter 
(Tiger) and 60 cases were performed with conventional catheter (Judkins). The patients 
of both group were overall well balanced for gender, age, risk factors, height, weight and 
body surface area. Diagnostic angiograms were successfully achieved in all cases via 
the radial approach. 
Total procedure time (4,45+1,82 min vs 5,42+2,32 min p0,02) was lower in the study 
group with statistical significance. Total fluoroscopy time (2,33+1,04 min vs 2,52+1,40 
min p0,82) was lower in the study group, but without statistical significance. The total 
volume of contrast medium (50 ml vs 70 ml p<0,0001) used was lower in the study group 
with statistical significance. And spasm was more frequently present in the conventional 
catheter group. Three patients required intraarterial nitrites to complete the procedure.  
There were no cases of femoral or contralateral arm crossover. There were no 
complications in those patients. 
Conclusions. The specific radial catheter showed to be suitable for the study of both 
coronary arteries compared to conventional, showing a decrease in producer time, 
fluoroscopy time and contrast medium use.
