@peterkistler3 @drjohnm The problem is not the ablation method thermal or non-thermal, RF or PFA. As with WACA, the real issue is that you can’t truly demonstrate transmurality. Moreover, the posterior wall is particularly challenging due to the thick septopulmonary epicardial fibers.

What’s the obsession with PWI in AF ablation? It may appear “safe & easy” ⁦@drjohnm⁩ BUT no randomised evidence & there is downside #TWIC Oct 10

Great talk @DJ_Lakkireddy on important limitations of PFA outside of the veins. Single digit long term durability in La Fazia et al. Dual energy sources can’t come soon enough for redo ablations. There need not be discussions with current PFA iterations for VT.

PFA with the pentaspline catheter achieves acute CS, LAA isolation and MI block, but lesion durability is poor at 3-month remapping @luigidibiasemd @aalahmadmd @giuseppe.stifano @WeeBodeMD @_nicolapierucci @dogi84md #AHAJournals #Epeeps https://t.co/n6p6Ft2ki4

An ideal outcome. A single morphology with bigeminal burden. PVC with an ATV3 morphology, localized and ablated at RCC/LCC commissure (65 msec pre QRS). Credit: @Ashit_EPS @isabelmauckEP @AbbottCardio #EnSite #TactiFlex #ViewFlex

@JRWinterfield @AbbottCardio @BrysonTindal Awesome case and ILAM map narrowing our ablation target. From being induced with singles to non-inducible at triples, great outcome.

A life changed. Young adult debilitated with frequent syncopal events. 5 months, symptom free post Cardioneural Ablation @Ashit_EPS. #GridX with OT Near Field, Fractionation & Peak Frequency Emphasis overlay enhanced localization of GP's. #CNA #Syncope #EPeeps #CardioTwitter

Do you really wonder the best GP mapping strategy so far A combination of EGM characteristics by Ensite X @AbbottGlobal @AbbottNews and anatomy by @inheartmedical This is just a trailer Just follow our live case in #EHRA2025 @escardio @EHRAPresident @SergeBoveda

Case after case - Wavefront Direction is Key: Pacing perpendicular to WADLs is best for identifying fixed lines of block that perfectly match the VT isthmus lateral boundaries. @BIDMC_VT with star fellow Gabriel Odozynski, maps with @sarah_chomos #ablateVT

Incredible recent #ablateVT case, refractory to multiple outside epi-endo ablations and SBRT. Respect to @DrKatrapati for taking the lead as our new attending. Flawless, precise, elegant. Proud🙏 Spoiler alert: ILAM showed the isthmus between 2 fixed LOB on the epi.

The notorious papillary muscle PVC. Originating from lateral aspect of the pap, these bigeminal PVCs were eliminated during the first RF session with the help of the tried and true PDX method. Link to publication: https://t.co/oYeBQ5aC2O

An unstable VT. Mappable with #StaMP. Guided by S3 Protocol. @JeffHsingMD @EP_EmilyS - StaMP @DrRoderickTung - S3 Protocol @ivroca - PDX Technique @B_Naz_MD - #EnSite @AbbottCardio

A patient frequently burdened with these PVC's originating at an anterior lateral attachment network of trabeculae carneae. Elongated strands of muscles lining the LV that attach to the solid portion of the LV wall. Permanently suppressed by #TactiFlex at site of 99%

Cardioneural response at #EnSite Fractionation Map perivenular target during WACA. @Ashit_EPS @AbbottCardio #PMA

My PVC summer continues! 120 ms QRS PVC suspicious for fascicular origin near PM pap. 2 targeted exits and 2 morphology changes later finally got it-mapped earliest Purkinje 30 ms pre at the septal insertion of a LV false tendon. Great mapping @forkknifecab_EP #EPeeps

Abrupt V3 transition with V2 pattern break, and this time got it from R-L interleaflet triangle (ILT) within seconds. 27 ms pre-QRS. V2 pattern break so likely too close to pLAD from GCV/AIV, so didn’t waste time there. Great mapping @georgecrowell #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
