Omnipolar technology
T or F: Omnipolar technology can be used with any Abbott SE catheter?
F
must be done with the grid due to electrode configuration
How can we rebuttal docs who like NavX (impedance) mapping?
its "non-linear" and impedance based which could cause map-shift or drift due to local impedance changes (e.g. sweat, irrigation, grounding pads). Doc cannot easily go from NavX to VoXel and vice versa
How many electrodes does HD Grid and Optrell have?
HD Grid is a 4x4 grid of electrodes with 16 total electrodes. Optrell is a 8x6 grid with 48 total electrodes.
What is a Ominpolar Technology
Ability to see signals in 360 - overcoming bipolar blindess to show a wavefronts direction, speed, and "true egm".
rebuttal to: Ensite X is easier to set-up than CARTO
- 12 patches
- real estate on small patients
How is electrode spacing measured between HD grid and Optrell? Bonus - what is the electrode spacing between the catheters
Abbott/HD Grid often measures electrode spacing as edge-to-edge, and Optrell measures center-to-center. The HD grid spacing is 3mm (e-e) or 4mm (c-c); Optrell is 2.4 mm (c-c).
How would you rebuttal "I really like using the HD grid because I can see OT vectors and avoid bipolar blindness"
- OT vectors do not show speed and are hard to see on the map
-Optrell vectors show speed, direction, and timing!
-CARTO can show local optrell vectors, but also has ripple and coherent to show global depolarization
-Dr. Anter published that high-density mapping with a roving catheter minimizes the impact of bipolar blindess
How would you rebuttal a doc saying "I really like LiveView dynamic mapping to find gaps"
Possible responses:
- Able to map gaps, assess data to find gaps
- Reverse mapping/Escape Mapping for single TS, minimal cath exchanges
-Optrell LCV to view breakthrough, directionality, and speed of wavefront!
What is the electrode size of the HD Grid and Optrell
HD Grid has 1mm length electrodes; Optrell has 0.46 mm electrode size
-optrell is atraumatic and has tighter and smaller electrodes for improved signal quality
-new LAM software can annotate late potentials for timing and/or substrate - option to show highest voltage amplitude
-We provide ICE integration, sheath visualization, LAM software, ripple, pattern matching/PASO, quick-map, and other tools to drive an efficient accurate VT workflow
A fellow says "Abbott can do ILAM, and is better for VT cases". How can we rebuttal this claim?
Possible responses:
-We have a new software that lets us annotate consistent late potentials automatically, in real time, with minimal user guidance to create late activation maps
-We can perform dynamic window of interest
-Our optrell catheter is atraumatic, flexible, has 48 electrodes with small spacing, to allow for fast and high quality Ventricle maps
- Optrell can show real time directionality and speed of conduction, possibly helping delineate slow zones
- Ripple shows raw data, irrespective of LAT, to show wavefront propagation, slowing, and even fractionated areas (i.e. ripple bars linger with varying amplitude over an area)
-If patients convert to VT we can use our QuickMap feature to map in seconds.
How can we reply to a physician that says they want lots of accurate points?
Optrell can take up to 42 points, whereas HD grid can only take up to 36 points per beat. Optrell also has smaller electrodes, tighter spacing, and TruRef which all improve signal quality. Optrell and Octaray also have a large coverage area
For a million dollars - describe how Ominpolar Technology calculates omnipoles, wavefront direction, and velocity
A physician asks if CARTO has s
oftware similar to Peak Frequency. Define
WaveFront annotation is able to annotate the sharpest unipolar slope which corresponds to when wavefronts are under the electrode. We have truRef technology to help sharpen signals and reduce impact of far-field signals. In combination with high density mapping, small tight electrodes, and visualization tools we can get a great sense of near-field depolarization
Optrell is bi-directional and comes in DF and FJ options, whereas HD grid comes in only DF curve. The tip of the Optrell is also atraumatic and can flex to conform tissue
