Tiger catheter is used for transradial coronary angiography. If Judkins catheter is used for transradial coronary angiography both right and left Judkins catheter have to be used to engage the respective coronary ostia. This means that a catheter exchange is required for completion of coronary angiography. While using the transradial route, the more the number of catheter exchanges, more likely it is get radial artery spasm. Severe spasm can cause catheter to be trapped within the artery. The advantage of tiger catheter is that the same catheter can be used to engage both the right and left coronary artery.
