Effect of Inspiration
α

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.

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 – 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.

Good for dilated

need extra reach
Ultimate 2 and 3 are more like
Amplatz catheters that get
support at the bottom of the
aortic root and give you more
“reach”
Ultimate 3
• The Ultimate 3 is an
Ultimate 2 layed out a little
further.
• This catheter is for dilated
aortas or extreme takeoffs.

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

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.

Right IMA Angiography
Panel A: the IM catheter
cannot selectively engage
the right IMA because of its
sharp origin angle providing
suboptimal images.
Panel B: a more angulated
catheter, such as the IMVB1, can selectively
cannulate the right IMA
without difficulty providing
optimal angiographic
opacification of the vessel.

Considerations for Using 5F Guide Catheters
n=171
% of Patients
• Miniaturization of products
allow 5F use
• Small radial arteries may not
be suited for 6F guides
• Less spasm, less patient
discomfort
• Lower incidence of radial
vessel occlusion
• Less contrast/ injection = less
nephrotoxicity

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.
