PCI Questions with correct Answers
what are guide catheters - answer the "tunnel" through which all other equipment
reaches the lesion
what do guide catheters provide a means for - answer They provide a means for
contrast injection with or without the presence of the balloon catheter
what do guide catheters have the capability for - answer Have the capability for
accurate pressure monitoring even with equipment within their lumen
Characteristics of guide catheter - answer Large inner lumen; thinner walls; stiffer
body
large inner lumen - answer We'll be putting a lot of things inside it
thinner walls - answer Not as thick as the diagnostic catheters
stiffer body - answer Support is more pronounced than what we see in the
diagnostic; Have to be stiff to sit and hold position because we're going to be in for a
while; Last thing we want is for a guide catheter to slip out and move
Characteristics of the guide catheter tip - answer soft, atraumatic, radiopaque, and
non-tapering; has to be soft because it will be sitting in the ostium, but radiopaque so
that we can see it
Catheter Body Construction--inner: - answer lubricious material (Teflon), to reduce
friction; we want the inner portion to be incredibly slippery, not stick, we want everything
to glide through it as easy as possible
Catheter Body Construction--middle: - answer composed of a wire/plastic braid for
torque response and support
Catheter Body Construction--outer: - answer smooth, nonthrombogenic, composition
allows for further support
nonthrombogenic outer coating of catheter body - answer So we don't have to worry
about clots while we're up there working
What sizes do guiding catheters come in? - answer 5—9 french size with some
specialty catheters in a 10 french size
What is guiding catheter selection normally based upon? - answer the type of
diagnostic catheter that was successful in obtaining the angiograms during the
, catheterization; Ex: If JL4 diagnostic catheter worked, we'll try a JL4 guiding catheter; If
we had a problem we might try a different kind
T/F: Besides the normal configurations: JL, JR, AL, AR, IM, MP, there are also many
shapes specific to guiding catheters. - answer True
What are 4 of the shapes specific to guiding catheters? - answer EBU, VODA, HS
(hockey stick), FL (femoral left)
V. - answer Additional Features
What are some additional features for guide catheters? - answer SH (side hole); ST
(short tip); SH/ST
SH (side hole) - answer Allows blood to flow through so we don't completely block
ostium
ST (short tip) - answer If the tip of the catheter is getting pulled into the ostium we
might want to try a short tip
Guider Selection Criteria - answer The size and shape of the aorta; The location and
position of the coronary artery ostium; Lesion location and morphology
The location and position of the coronary artery ostium - answer Is it sideways,
anterior, posterior, inferior, superior, etc
Angioplasty Guidewires: purpose of them - answer To transverse coronary anatomy
safely without damaging the vessel, and to support the balloon catheter
what does failure to cross the lesion do to the procedure - answer Failure to cross
the lesion terminates the procedure; If we can't get a wire across the lesions, 99.9% of
the time we will cancel the procedure
flexibility - answer Can't be rigid and straight; has to bend safely without causing
damage to vessel
visibility - answer If you can't see past lesion you can't see where you're going
support - answer For catheter to go on it
trackability - answer Through course of vessel
What is the physician guide wire selection based on? - answer personal preference,
lesion type, and past experience
