Thank you sir for your impressive talk. I have an issue cropping nowadays. For many years I have been using the JL and JR for diagnostic without any issue. I just changed working hospital where they use TIG mainly and I'm having lots of problems for diagnostic angiography.Any tips or advise you can give please.
The main issue is that Tiger is a Tiger 4, ie, it has a long arm of 4 cm, frequently suboptimal radially for LCA. JL 3.5 is my preferred LCA diagnostic catheter radially, and I reserve JL4 for large aorta. The issue you are having is the issue I explain under 06:57 : the Tiger arm is long and its tip frequently points down below the coronary ostium. As I explained, there are 4 ways of fixing it: use deep breath to push the left main down (quickly advance your catheter during deep breath), or pull up with steep clock torque, or engage from below (3B). The best option is, however, to use a 3.5 arm catheter: just use JL 3.5. Tiger does not come in 3.5 length, but its cousin, Jacky catheter, is available in 3.5 and you may try that one as an alternative.
