Nice case of Ischemic VT-done by Dr. Azlan-IJN. #EnsiteX -OTNear Field-helped to identify HighFreq Isthmus,Nice correlation between SP Map-VT Isthmus and Corridors delineated by @ADAS3D, special thanks to @Callme_DrNeil for sense protocol & @ivroca for ADAS O/L webinars teachings

Atypical AFL from earlier this week w/ @MBarakatMD and 2nd time trying OT Near Field! I had always used Abs Peak when mapping these, but I feel the annotation w/ Near Field is cleaner and adds a crispness factor to the map, especially in the isthmus zones. Where to ❤️‍🔥 #EPeeps?

[Matthew Melcher @MattMelcherPA]

First Isch VT case using OT Near Field. Combo of low voltage & high peak frequency added specificity to substrate/functional map in SR, as well as during VT (like described by @Arritmias_HRC). LV + high PF area co-localized to isthmus of 3 VT’s and lead to 1st burn termination.

Over 500ms of fractionated EGMs across #HDGrid, capturing entirety of TCL during this left atrial flutter. Hx cryo PVI.

#HDGrid + #EnsiteX + #OT. This AAFL was induced on a De Novo AFib patient while gathering our initial CS Pace ILAM map. Gorgeous signals were found on the posterior wall of the LA. Flutter was induced while mapping and we knew just the spot to go🎯. #EPeeps @JohnSummers_MD

[Kevin Brady @Hapa_EP]

Pesky focal AT originating from Bachmann's bundle. Mapped with #HDGrid and OT on Voxel mode. Even though it was earlier by 10 ms on the left, tachycardia did not terminate until RF was delivered on the RA side. How many #Epeeps have seen this before? Case performed by @Maeskander

Left lateral accessory pathway during RV pacing with an epicardial jump into the LA. First burn termination in 1.2 sec by @dskumarmd

First ischemic VT on #EnsiteX w/ full magnetic Voxel mode. Incredible stability for a conscious sedation case, including one CV when VT degenerated to VF. After a few burns in the critical isthmus, no VT inducible on isuprel and triple extra-stimuli! Case performed by @Maeskander

[Megan Malladi @MeganMalladiEP]

Epicardial jumps are not only for the ventricle! LAFL with TWO epi jumps. Ablation resulted in 30msec jump at the posterior wall exit and termination at the roof. Easy mapping with #EnSiteX and #HDGrid! #EPeeps @AbbottCardio Map: Dr. Stuart Adler

[Glen Schoenbeck @GS_EP23]

ARVC VT is no match for HD Grid & TactiCath SE ! High density mapping allowed for a quick map showing multiple circuits with one common isthmus. TCSE in the isthmus gave us accurate CF data and terminated VT ! @RyanZimberg @AbbottCardio #AbbottEP #HdGrid #TCSE #HighDensity

#4: Mapping Unstable Ventricular Tachycardia

This case by @PraveenRao_EP from August 2022 highlights the importance of carefully analyzing electrograms and substrate maps prior to induction of VT: https://t.co/G9akjFRYFN

[Julia Beckerle @BeckerleJulia]

Fantastic VT ablation done by @jonascooperEP! By utilizing #HDGrid, we collected over 20,000 points in 13 minutes providing a detailed map of the VT circuit. VT termination at the site of the green ball. Check out those signals on Grid C4-B4 & D4-C4 🤩 @AbbottCardio #EPeeps

[Kevin Brady @Hapa_EP]

Double loop AAFL (CW MA + Roof around LPVs). All PVs were confirmed to be isolated before induction (LIPV was the only vein reconnected from prior PVI and we touched up with RF anteriorly beforehand). Should we perform a lateral mitral isthmus line? #EPeeps #Flutter

Mapping Unstable VT: Video demonstrates sinus rhythm sparkle map overlayed on top of the omnipolar voltage map, showing the conduction is delayed over the low-voltage channel.

[Kevin Brady @Hapa_EP]

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?

[Kate Seigle @kate_potentials]

It’s been a fun couple of weeks at @MUSC_EP with Ensite X v2.0. First burn termination of atypical flutter #EPeeps #OnlywithOT @JRWinterfield @ChauVoMD

[Aaron Matthews @AMatthews0]

Interesting PVC at @MUSChealth with @JRWinterfield. PVC was quickly mapped to lateral wall near ALPM insertion. A False Tendon was seen on ICE connecting from PM to basal Septum. LAT there was earlier than rest of septum. Are we seeing the FT activation?#Epeeps @AbbottCardio 1of3

WPW pattern on EKG and wide complex tachycardia termination with adenosine in ER. Orthodromic or antidromic tachycardia? 👀 #HDGrid and Omnipolar Technology (OT) rapidly discovered the truth. #TrueEGMs @RajeevJoshi400 @AbbottCardio

[Tyler Hunt @EP_TylerHunt]

Antero-lateral papillary (ALP) PVC mapped on #EnsiteX’s magnetic primary (Voxel) mode. ICE and #HDGrid was used to map and locate the target 🎯. Earliest point was -52 early on the medial side of the ALP. @JohnSummers_MD
