QDOT
Where is QDOT indicated for use? Must name at least 3 types of procedures.
Everything except AVNRT
How many thermacouples does TactiFlex have vs QDot?
Tactiflex has 1 thermacouples
QDot has 6 thermacouples
What are the V8 Base enhancements?
LAT Velocity Vector
Stability+ (VISITAG)
General Enhancements
What is the only other irrigated temperature control catheter in the market besides QDOT?
Sphere 9
Dr Rasmi said, QDOT has 3 things to remember...
3 Microelectrodes
6 Thermacouples
OI - Optimized Irrigation
Versus TactiFlex, how many microelectrodes does QDot have and what's the distance between them?
Qdot has 3 Microelectrodes at 1.5mm
TactiFlex doesn't have microelectrodes
Complex Signal Acquisition
Automatic Point Acquisition
Enhanced CONFIDENSE
Multipolar Mapping (OPTRELL)
What is the ideal EP strategy when using QMode+ and why?
To be stable and confident in point by point ablation
You only have 4 seconds to create the durable lesion so you need to be very stable.
What is QMode+?
What power (wattage)?
What duration (# seconds)?
What stable irrigation rate?
QMode+ is vHPSD (very high power, short duration).
90 Watts, 4 seconds, and 8ml/min
What's our 1st pass isolation rate vs TactiFlex?
89% for QDOT
80% for TactiFlex
What is stability+? And how does it work?
It works by separating the movement due to respiration to produce a Stability+ Compensated Motion.
What catheter also has 6 thermocouples?
DiamondTemp (DT) has 6 thermacouples and is an irrigated catheter
Name the 4 "bullseye" heat distribution readings/colours and what does this mean?
Blue = Mapping / Lost your contact
Red Bullseye = Catheter is perpendicular
Red at the bottom = Catheter is parallel
Orange = Embedded / Inside pouch/etc
SAFETY vs TACTIFLEX
What's the comparative major complications rate for QDOT vs TACTIFLEX?
QDot = 0 complications
TactiFlex = 4.3%
What are the 2 catheter locations to collect contours for the LA with CARTOSOUND FAM?
1. RA with transducer directed into the LA
2. RV with transducer superiorly directly into the LA
Name 3 competitive contact force catheters?
StablePoint (BSX)
TactiFlex (ABT)
TactiCath (ABT)
a) Fill in the blanks. QDot is the 1st _______ control, irrigated catheter?
b) What is the difference between power control mode and temperature control mode?
a) Temperature Controlled Irrigated Catheter
b) WATT is the cut off for power control mode. Whereas TEMPERATURE (reading) is the cut off for Temperature Control Mode.
Using at least 3 efficiency claims, do a 30' elevator pitch to Dr Rasmi.
Dr Rasmi is a big TactiFlex user but cares deeply about operational efficiency.
•Procedure time ~105–130 min ~12.5% shorter
•Total ablation time ~46–67 min ~ 9% shorter
•RF application time ~8–34 min ~60% shorter (QMODE+)
•Fluoroscopy time ~6–9 min slightly longer
•Fluid Volume ~380–570 mL ~13% less
What is the LAT Velocity Vector used for?
1. Used to give a representation of the ventricular activation over a substrate map during normal sinus or pacing
Name the main difference between AGILIS and VIZIGO?
VIZIGO is integration with CARTO, AGILIS not
VIZIGO can deflect 180 degrees clockwise and counter-clockwise.
AGILIS is 180 degree clockwise and 90 degrees counter-clockwise.
