6 Effect of Inspiration α α A B Panel A: During expiration there is a more acute angle (α) between the brachiocephalic trunk and the ascending aorta, therefore the wire takes a more horizontal a more horizontal direction towards the descending aorta. Panel B: During deep inspiration, the diaphragm lowers the heart and straightens the angle (α) between the brachiocephalic trunk and the ascending aorta. The wire takes a more vertical direction towards the ascending aorta. 6

7 Radial Side Selection The back-up force provided by the guide catheter differs according to the radial side Courtesy Francesco Burzotta 7

10 Catheter selection Learning curve Single vs. Double catheter technique Judkins: JL3.5 and JR4 or 5 Single catheters: Tiger, ULT1, Jacky, ULT2, Sarah, ULT3, Kimny, Fajadet TRA PCI Right: JR4 or 5 Left: EBU 3.5 Single Catheter Technique: Ikari L 10

11 Diagnostic Radial Catheters Merit Ultimate 1 Merit Ultimate 2 Merit Ultimate 3 Merit Ultimate 4 These are radial catheters used to cannulate the right and left coronary arteries with just one shape.

12 Ultimate 1 and 4 The Ultimate 1 and 4 are come from the Judkins Left catheter This is why they are the most popular of the Ultimate catheters. Ultimate 1 and Ultimate 4 are just a relaxed version of a Judkins Catheter

13 Ultimate 1 why it s better than the Tiger The Tiger has a pinch point that makes it vulnerable to fold back on itself. The tertiary curve allows for added support.

14 Ultimate 2 and Ultimate 3 from Amplatz 3.5cm 4.0cm Ultimate 2 (3.5cm) Terumo Jacky Good for dilated roots where you need extra reach Ultimate 3 (4.0cm) Terumo Sarah Ultimate 2 and 3 are more like Amplatz catheters that get support at the bottom of the aortic root and give you more reach

15 Ultimate 3 The Ultimate 3 is an Ultimate 2 layed out a little further. This catheter is for dilated aortas or extreme takeoffs. Ultimate 3

19 Catheter Selection: Femoral vs Radial Catheter Manipulation Technique Transradial approach can involve more tortuosity than the femoral approach TRA necessitating small (finger-based) clockwise and counterclockwise torquing movements and active catheter holding as there may be multiple friction points in the subclavian and the aorta JL 3.5 Radial Different curve mechanics, sizing and backup support JL 4.0 Femoral 19

20 Transradial Curves for Left Coronary Extra Backup Workhorse curve for left coronary artery Sizing suggestions: JL3.5 = EBU3.5 JL4.0 = EBU3.75 Comparable to: Merit: SBS ConcierGE Cordis: XB, XBLAD BSC: Muta Left, Radial Curve, Brachial Curve Apply torque to point the tip to the left coronary cusp and turn catheter. Pull wire back and the catheter will engage the left coronary artery. Backup support from the sinus of valsalva 20

22 Transradial Curves for Right Coronary Judkins Right Standard curve for right coronary artery (may be particularly useful for inferior takeoffs) Sizing suggestions: Same as femoral approach Comparable to: Merit: Judkins Right Cordis: Judkins Right BSC: Judkins Right Judkins engagement technique, similar to femoral approach. Apply a clockwise rotation to engage right coronary artery 22

48 Right IMA Angiography Panel A: the IM catheter cannot selectively engage the right IMA because of its sharp origin angle providing suboptimal images. Catheter Tip Panel B: a more angulated catheter, such as the IM- VB1, can selectively cannulate the right IMA without difficulty providing optimal angiographic opacification of the vessel. A B 49

55 Conclusions Find the catheter that works best for you Practice makes perfect Consider starting with Judkins and transition to single catheter technique once you feel more confident. Guiding catheter engagement and support represent significant barriers to transradial procedural success Keep the guidewire in the catheter until you cannulate Knowledge of guide catheter selection and technique enable successful PCI Complex PCI is achievable with existing equipment CTO, bifurcations, rotational atherectomy TR specific guiding catheters may offer advantages Dedicated sheathless guiding catheters now available in the US, but sheathless is possible with standard equipment. 56
