RCES Part 3 Exam Review Questions with
Verified Correct Answers
Room temperature heparin saline (flush)
What fluid is used to perfuse irrigated tip ablation catheters?
Less char and thrombus formation
Higher power delivery to cardiac tissue
Compared to plain RF ablation, irrigated tip catheters have the 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
Cool, pulmonary embolism
During typical AFL ablation it is best to use _______RF catheters to prevent _________.
Small burn lesions 2 to 3 mm deep
30 seconds of a successful 7F, 4 mm RF catheter ablation typically typically causes:
Tissue heating/burning
The main mechanism of RF ablation is:
Increase flow to 10 to 30 mL per minute
With standard saline closed irrigated tip ablation catheters, to avoid endocardial burning and
char formation when more than 30 W are being delivered:
Peristaltic (roller)
What type of pump is usually cooled or open irrigated ablation catheters?
Increases flow to 8 to 30 mL per minute
When ablasion comes on with open irrigated tip catheters the irrigation pump:
, In-line bubble detection
With cool or open irrigated ablation systems all infusion pumps contain alarms for "open door"
and:
N2O (nitrous oxide) The same as regular cryo-ablation
The cryo-ablation balloon for PVI is inflated with:
Inflated with N2O, senses any leak in the inner balloon
The cryo-balloon (arctic front) has two balloons one inside the other. The inner balloon is
_______the outer balloon _______.
Never pull the balloon sheath off the catheter, prior to insertion, place the balloon in saline
flush and dislodge any adherent bubbles.
How should you prep the cryo-balloon prior to use?
Never pull back on the catheter, as it may damage adherent tissue.
The main precaution while the cryo balloon is inflated during a PVI cryo-ablation is:
12 F
The arctic front cryo-balloon requires a _____ inner diameter sheath:
Cryo-ablation
What ablation Method is least painful?
-30°C for less than 60 seconds
At what catheter temperature and time is cryo-mapping performed?
AV block is reversible by thawing the region
When using cryo-ablation in AVNRT, if AV block develops:
Distal electrodes show electrical noise
In cryo-ablation, formation of an ice ball at Catheter tip and adherence to the myocardium is
indicated when:
Cryo-ablation
Parents want their child to have the safest ablation to preserve the AV conduction. What
ablation method would be best for a young person with AVNRT?
