Electrophysioloic mapping - NOGA vs CARTO ?

[LarsChristian]

Hi,
I am not sure if this is the correct forum for this kind of question, but here we go:

I am currently working on a paper and i need som background information on electromechanical mapping of the activation sequence of the heart. As for now i interpret the papers i read as follows (1):

Innvasive electromechanical mapping:

"evolution of electrophysiologic mapping":
1. echo and angio mapping - before the 1990s
2. Non-fluroscopic catheter based procedures - 1990s - current
- CARTO - the first - allows intracardiac detection of voltages - Uses magnetic fields beneath patient to navigate the different percutaneous catheters in the chambers of the heart
- NOGA - similar to CARTO - also allows for "drawing" inner borders of endocardium.

Noninvasive electromechanical mapping:
Currently only experimental set-ups available? Are there currently any clinicaly available noninvasive techniques for electromechanical mapping?
As for now I've only found Electromechanical wave imaging (EWI) studies from Columbia university (2,6)

And can someone elaborate the terms electrophysiological mapping vs electromechanical mapping? Can you use CARTO for both?
And the review article seems to differentiate between electrophysiological mapping, electromechanical mapping and "acitvation-motion mapping".

Which of these systems are most commonly used in the clinics/electrophysiology lab today?

And finally, whats the difference between CARTO and NOGA ? (Is NOGA software which utilizes CARTO?)
- It seems that NOGA XP is used only for electromechanical mapping, while CARTO XP also can be used for ablations etc. (3,4) - same company which produce both units.
- It seems that determination of position of the catheters are based on the same technology. With a "stationary" navigation patch beneath the patient with ultralow magnetic fields, and corresponding in the catheter tips which allows for accurate visualization of the catheter position. (5)

That beeing said, Are there any other vendors offering similar technology? or similar results?


Any help would greatly be appreciated!
Thanks in advance!

Finally found a great review article on the topic. It should rather be NOGA vs NavX electroanatomical mapping. (7)

Now, I have to say that I am a little disappointed with the response rate here, >900 views and not one reply. I was hoping for some response. But for now, I found what I was looking for. Maybe this forum is not as relevant for this topic as I thought.
