5. Ideal Guiding Catheter
• Safe, soft tip, low risk of dissection
• Easy to engage and manipulate
• Coaxial engagement
• Backup support
• Stable

6. Techniques to Improve Support
• Selection of stiffer, larger guide
• Deep intubation  Active support
• Guide extensions
 Guideliner, Guidezilla
• Balloon Anchoring
• Buddy wire
 Stiff wire in LCx while working on LAD

29. RIMA
angiography
IM catheter cannot
selectively engage the right
IMA because of its sharp
origin angle providing
suboptimal images.
A more angulated catheter,
such as the IM-VB1, can
selectively cannulate the
right IMA without difficulty
providing optimal
angiographic opacification
of the vessel.

38. Conclusions
• Guiding catheter engagement and support
represent significant barriers to transradial
procedural success
 Keep the 0.035” guidewire in the catheter until you
cannulate
• Knowledge of guide catheter selection,
physics, and technique enables successful
PCI
 Use the catheter you like best and works for you
• Complex PCI is achievable with standard
guiding catheters
 CTO, bifurcations, rotational ablation
• More coming in the next lectures
