Insights
The Judkins catheter via left radial artery access is safer than the Tiger-2 catheter via right radial artery access, with lower radiation exposure and fewer complications. However, it necessitates a higher contrast volume.
Area of Science:
- Interventional Cardiology
- Vascular Access Techniques
Background:
- Radial artery access is common for coronary angiography.
- Different catheters and access sites may impact safety and efficiency.
Purpose of the Study:
- To compare the safety and efficiency of Tiger-2 catheter (right radial artery) versus Judkins catheter (left radial artery) in coronary angiography.
- To evaluate procedural outcomes, complications, and resource utilization.
Main Methods:
- Retrospective analysis of 487 patients undergoing coronary angiography.
- Group 1: 172 patients with Judkins catheter via left radial artery.
- Group 2: 315 patients with Tiger-2 catheter via right radial artery.
- Comparison of baseline characteristics, procedural data, contrast volume, drug administration, fluoroscopy time, radiation dose, and access site complications.
Main Results:
- No significant difference in baseline characteristics except hypertension and age.
- Higher contrast volume used in the Judkins group (left radial).
- Significantly greater radiation dosage and absorbed dose to the kidney (AK) in the Tiger-2 group (right radial).
- Tiger-2 catheters were changed more frequently than Judkins catheters.
- No statistical difference in access site change between groups.
Conclusions:
- Judkins catheter with left radial access appears safer due to lower radiation exposure and fewer complications compared to Tiger-2 with right radial access.
- Left radial access with Judkins catheter requires a higher contrast volume.
- Further research may optimize catheter selection and access site strategies for improved patient outcomes.
Abstract:
We sought to compare the safety and efficiency of Tiger-2 in the right radial and Judkins catheter in the left radial access. We retrospectively collected data of 487 patients, involving 172 patients after coronary angiography with Judkins on the left radial artery and 315 patients with Tiger-2 on the right radial artery access. There were no differences in baseline characteristics, except for hypertension ratio and mean age. There was a difference in pulse absence on the radial artery. The volume of contrast used was higher in the Judkins group. Both groups differed in the amount of drugs administered (NTG and heparin). Fluorescence times were comparable between groups. Radiation dosage and AK was significantly greater in the Tiger-2 group. The Tiger-2 catheters were significantly more often changed to another type of catheter (100 changes) than the Judkins (12 changes). However, there was no statistical difference in access site change. Judkins with left radial access seems to be a safer option because of the lower radiation exposure and less incidence of complications than Tiger-2 with right radial access, however, it requires a higher volume of contrast.

01:11Assessment of radial pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:

01:25Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
