@dkenigsberg @NDalladas @martinezcarl3D @AbbottCardio Nice case. What do you target specifically during AF with you peak frequency maps.

Conversion of #PersAFib to atrial flutter to a micro-reentrant atrial tachycardia and finally to #NSR by employing an experimental stepwise #ablation protocol relying on peak frequency mapping and OT nearfield to identify target substrate.

Great atypical flutter map with #EnsiteX @AbbottCardio @AlexandriaSaban Previous CTI ablation. RA was activated passively with clear block at CTI. Then mapped LA - TCL delayed slightly on TSP, and identified focal reentry around septum. PPI-TCL 0 and got #oneburnterm

@PVC_on_HERS @senthil_dorai Nice. Showing far field SVT signals with the activation superior to inferior in the vein.

Fireworks celebrate Independence Day, and independent firing showcases independence from the LA 💥
Fun proof-of-concept with #LiveView and #OTNearField on #HDGrid showcasing activation sequence within this active RSPV following isolation by @senthil_dorai with #TactiCathSE.
#LiveView allows for beat-by-beat identification of activation sequence independent of LA activation.

Interesting AT - atypical flutter on ECG but no previous ablation or surgery. Small focus of re-entry corresponding to discrete scar on LA PW. Beautiful #HDGrid signals, terminated with catheter pressure here. #EnsiteX @AlexandriaSaban @JamesEP14 @ProfDConnelly @JubileeHospital

An enjoyable case and nice to use the new software OT near field. Great result for the patient @AbbottCardio #EPeeps #abboutproud

Nice redo PVI using #nearfieldOT #HDGrid, gaps in WACA clearly highlighted resulting in efficient workflow @AbbottCardio @JamesEP14 @AlexandriaSaban @claire_doole @JubileeHospital @ProfDConnelly

Really enjoyed this Focal AT at the Golden Jubilee National Hospital with @richardjdobson1 Using OT technology. Sporadic bursts of AT during the case. Lovely warm up response during ablation. Great result for the patient. #abbottproud #HDgrid

Nice crista atrial tachy with @JamesEP14 @AbbottCardio. OT allowed us to hone in on critical area despite stop-start nature of tachy and variable cycle length #HDGrid
English
@Callme_DrNeil @richardjdobson1 @AbbottCardio Because it was focal as well we managed to put the CL out and collect data during brief periods of tachy. Had a lovely warm up response burning as well.
English
@richardjdobson1 @JamesEP14 @AbbottCardio That's a good point
It's independent of cycle length right ?

Second WPW more challenging. Post VF arrest; posteroseptal pathway (very short ERP) in a big CS diverticulum. Eventually put a circular (PV) mapping catheter in there, tagged the best site with @abbott mapping system, then ablated there with Tacticath. Should prevent further VF!

Brilliant day in the EP lab today - in addition to a couple of parox AF cases, I managed to slay 2 dangerous Wolffs!
First one easy - pre-excited AF, SPERRI 240ms. Straightforward L sided pathway that blocked on the first burn @epeeps

First atypical flutter mapped on Ensite X! A bit late to the party with the new system, but seemed to work quite well using Omnipolar technology on NavX mode. Map stability was solid during the whole case, so we did not switch to magnetic Voxel mode. Where would you burn #EPeeps?

I do like a full colour propagation map. #Epeeps #Abbottproud

We love to see the discussions #EPeeps are having on #CardioTwitter over great threads like this one from @Hapa_EP. Thank you for continuing to collaborate for these complex case presentations. Safety Info: cardiovascular.abbott/us/en/hcp/prod…

Great day in the EP lab today.
Three AVNRT ablations in the morning - then a 20 ♀️ with incessant L posterior fascicular VT.
Thanks to @JamesEP14 @AbbottCardio - lovely Purkinje potentials on #hdgrid, linear lesions delivered perpendicular to the bundle

Ischemic VT Case - PT w/ recurrent Monomorphic VT hemodynamically unstable & unmappable. Opted to use #ILAM to identify decel zones. Based on ILAM & substrate, what would be your #ablation strategy? #EPeeps #AblateVT #Mapping @brysontindal9 @DEEPmapping | youtu.be/Tk3sk9VbmEU
