Amazing VT case done by @KoerberScott! By utilizing #HDGrid, we were able to collect over 14,500 points in under 16 minutes. Grid highlighted beautiful mid-diastolic potentials and lead to VT termination in 4 seconds of coming on RF! @AbbottCardio #EPeeps

Hey #EPEEPS How's this for a circuit?!? Atypical Afl with a long narrow channel in a very low voltage area. EGMs spanning the full TCL were imperceptible on the recording system, but not on Grid with Nearfield-OT. Frequency based mapping annotates the critical isthmus with almost-perfect accuracy. Less than a handful of bad points in an 18k point map, voltage cutoffs of 0.1 mV would've hid the majority of this isthmus on the map. The propagation map below has voltage cutoffs of 0.02 mV. Voltage, however, is still useful in conjunction with frequency mapping. The whole channel lights up with low voltage, high frequency emphasis giving us a discreet target. Flutter termination when putting the catheter on the channel. AML to follow. EGMs and other associated images in the comments #EnsiteX #Abbottproud @AbbottCardio

Going...Going...Gone! LCC PVC perfectly ablated by @KoerberScott! #HDGrid pairs great with #PDXmapping method for cusps identification! First burn term with TactiCath SE 🔥 @AbbottCardio

Research Medical Center @researchmed and @HCAMidwest is excited to partner with @abbottcardio in performing the first US commercial AF ablation case using the #TactiFlex ablation catheter. @HCAhealthcare @DJ_Lakkireddy @JoeProvost7 @SarahElsener1 @rajeshkabramd

Awesome WPW case with @Jose_Phlin and @EPCatLady11 using Emphasis Map and #OTNearField on #EnSiteX. The timing Emphasis Map was set up to highlight V-A fusion. You can see activation crossing the valve & OT vectors even show the oblique nature of the AP. 🤤 @AbbottCardio #EPEEPS

We had an interesting case with @djdardenMD using #EnsiteX and #HDGrid. We mapped #OnlyWithOT and found this AAFL in a De Novo AF!

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

Another #AblateVT case to end the week. 67 y/o male ICM EF 17%, recurrent sustained VT refractory to meds, recurrent shocks. Entered lab in sustained VT. Mapped 3 clinical VTs. After 6hours, now in sinus. Thx to @RobP1999 for mapping. @MidAmericaHeart @saintlukeskc #EPeeps

Beautiful case of AVNRT with @KoerberScott! Performed low voltage bridge mapping to define the slow pathway. Safely ablated with #TactiCathSE 🔥achieving a slow junctional response! @AbbottCardio #AbbottEP

Correlation between sinus rhythm deceleration zones and critical sites for localized reentrant atrial flutter: A retrospective multicenter analysis, by @EPWoodsShop and colleagues heartrhythmopen.com/article/…

Great Micro-Reentrant AFL with @KoerberScott on #EnSiteX ! #OnlywithOT helped identify the critical isthmus with over 65% of TCL just below the LIPV! This entire LA map only took 13 minutes with over 33k points and led to a one burn term 🔥

Endo-Epi flutter termination guided by #ILAM #CCEP @omwazni @EPWoodsShop @50wattdoc @DanielAlyeshmer @MicheleB_MD @OCanoPerez @MonicaKorzon #ACES #EPeeps

Great first Voxel LA #EnSiteX case on a redo AF/AFL with @KoerberScott! Pt had previous CTI, convergent and surgical MV repair. Induced a mitral AFL, by utilizing #HDGrid, this channel was highlighted and we were able to achieve first burn termination 🔥 @AbbottCardio

Ended a long week with a nice left atrial flutter. @KaitlinG_EP

Had an interesting roof-dependent LAFL, #EPEEPS. We placed HPSD lesions at our suspected critical isthmus with no effect on the TCL. Switching to a longer RF application at a lower power terminated the tach. Did #OT show us an epicardial connection? #HDGrid #TrueEGMs #AbbottAF

@Segarspr and @subparsonsmaps using new technology to push the boundaries of what has historically been impossible. Innovative use of Omnipolar Technology for NoREF Mapping of a PW leak in AFib. #AbbottAF #OnlyWithOT #EPeeps

Great AFL case report by @KoerberScott! Initial mapping and signals led us to believe this was a left-sided AFL. By utilizing De Ponti Method and #HDGrid we were able to quickly see this was a CTI-dependent AFL! #EPeeps @AbbottCardio

Great #AbbottAF case on this redo pt. with @KoerberScott! By utilizing #HDGrid we were able to map both pre and post LA in 16 minutes with over 20,000 points collected. A total ablation time of 32 minutes was taken to re-isolate all 4 PVs! @AbbottCardio #EPeeps

There’s A LOT more to a Chest X-Ray than just the lungs! Via @radiologistpage #FOAMed

Three tachs gone thanks to @AlexBaherMD. First typical AFL, then atypical LAFL, and finally AT. #HDGrid lead the way to a 1 burn LAFL term and a 3 burn AT term. Grid signals > half the TCL at the LAFL termination site. 👀 #GridalisTotalis #EPEEPS @AbbottCardio
