What fluid is used to perfuse Room temperature heparin saline (flush)
irrigated tip ablation catheters?
Compared to plain RF ablation, Less char and thrombus formation
irrigated tip catheters have the Higher power delivery to cardiac tissue
advantage that they can maintain
lower tip temperatures with: (pick 2)
-less pain
- more accurate temperature
regulation
-higher tissue interface temperature
-Less char and thrombus formation
-higher power delivery to cardiac
tissue
During typical AFL ablation it is best Cool, pulmonary embolism
to use _______RF catheters to prevent
_________.
30 seconds of a successful 7F, 4 mm Small burn lesions 2 to 3 mm deep
RF catheter ablation typically
typically causes:
,The main mechanism of RF ablation Tissue heating/burning
is:
With standard saline closed irrigated Increase flow to 10 to 30 mL per minute
tip ablation catheters, to avoid
endocardial burning and char
formation when more than 30 W are
being delivered:
What type of pump is usually cooled Peristaltic (roller)
or open irrigated ablation catheters?
When ablasion comes on with open Increases flow to 8 to 30 mL per minute
irrigated tip catheters the irrigation
pump:
With cool or open irrigated ablation In-line bubble detection
systems all infusion pumps contain
alarms for "open door" and:
The cryo-ablation balloon for PVI is N2O (nitrous oxide) The same as regular cryo-
inflated with: ablation
The cryo-balloon (arctic front) has Inflated with N2O, senses any leak in the inner

The inner balloon is _______the outer
balloon _______.
How should you prep the cryo- Never pull the balloon sheath off the catheter,
balloon prior to use? prior to insertion, place the balloon in saline flush
and dislodge any adherent bubbles.
, The main precaution while the cryo Never pull back on the catheter, as it may damage
balloon is inflated during a PVI cryo- adherent tissue.

requires a _____ inner diameter sheath:
What ablation Method is least Cryo-ablation
painful?
At what catheter temperature and -30°C for less than 60 seconds
time is cryo-mapping performed?
When using cryo-ablation in AVNRT, AV block is reversible by thawing the region
if AV block develops:
In cryo-ablation, formation of an ice Distal electrodes show electrical noise

would be best for a young person
with AVNRT?
