The #VoltPFA insights keep coming!

Late-breaking results on Volt PFA System PVI durability and patterns help answer the question: does the pulse field ablation system matter?

Day 2 poster sessions at #HRS2026 truly showcased Abbott Science and innovative uses of our tools from A(trial) to V(entricular), and from imaging to mapping to #ablation.

Challenging 3D VT ablation where pt had previously undergone two ablations including bipolar RF and dual energy on another mapping system. Extensive endo and epicardial mapping and long endocardial lesions resulted in VT termination and noninducibility. #3DVT #intramuralsubstrate

I tried to tell you

[Jhan carlos Altamar @jhan791004]

@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.

[peterkistler MBBS PhD FHRS @peterkistler3]

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

[Roderick Tung @DrRoderickTung]

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

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).

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

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

[Roderick Tung @DrRoderickTung]

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. Diastolic buffet EGMs shown to feast on. 1s term.
