Up next at #EPLive2026: Dr. Wendy Tzou is presenting a recorded case on Bipolar Ablation! ⚡️🫀

When standard unipolar RF energy isn't enough to cross thick or deep intramural tissue substrates, switching to a bipolar configuration can be a game-changer for procedural success.

An excellent first in US experience with Volt 2.0 with ICE integration. Having used this technology in trial, LMR, and now 2.0, the newest version adds excellent maneuverability to a refined, effective, and safe platform. Bravo @AbbottCardio @uyaron @JoeProvost7

Unique case by @ChauVoMD at @MUSC_EP where two separate depth boundaries were identified by #HDGridX in a complex VT circuit with a one burn term at the site of mid diastolic signals. #Epeeps Have you seen multiple epi jumps mapped this clearly? #AblateVT

I’m proud to share lessons learned from the first in human report of sequential colocalized PF/RF lesions, delivered during the @AbbottCardio FlexPulse IDE trial to treat mitral flutter. @srissundaram @Nicky_P_MD #EPeeps https://t.co/3vGCZNcw9P

[Daniel Alyesh @DanielAlyeshmer]

Flex Pulse dual energy redo lessons learned:

1. PFA first pass PVI/PWI durable.
2. Can terminate mitral flutter during PFA.
3. Sequential PFA/RF safe and effective. Turn up irrigation if RF second lesion.
4. Very versatile catheter.

Caution, investigative not FDA approved.

Bipolar VT ablation across the PSP (inferoseptal process) and crux of heart with zero fluoro and ICE guidance. “Kissing catheters!” Enjoyed doing case with our newest partner Luke Cerbin:

[Daniel Alyesh @DanielAlyeshmer]

The first of its kind application of bipolar ablation across the inferoseptal process for refractory VT, proud to share this novel technique with @srissundaram @Nicky_P_MD

[Heart Rhythm Case Reports @HRS_CaseReports]

New Case for Education in the March issue!
Bipolar ablation from the right atrium and basal inferoseptal left ventricle to treat ventricular tachycardia arising from the inferoseptal process

Enjoyed assisting with some workflow and technology improvements in FIH trials of novel Viewflex X ICE catheter from @AbbottCardio -- we performed ablation of PVC from suspected intramural site with RF to septal RVOT and adjacent ASOV. Will be curious to see what @dhakalbish thinks with his @PennEPFellows based ICE approach in trials tomorrow. Contouring of key structures including pap muscles and ASOV shown below:

First focal PFA in the Mountain West using #TactiPulse! Psyched to be using this new technology! @srissundaram @DanielAlyeshmer

[Joe Provost @JoeProvost7]

Proud of Abbott EP’s significant presence here at #AFSymposium2025. Grateful to the physician investigators and innovators pushing the next generation of PFA tools forward.

[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.

[Daniel Scherr @DanielScherr3]

Exciting day with @AbbottNews @MedUniGraz ! 1st case of point-by-point PFA PVI in the FOCALFLEX trial in central Europe. Great update to an excellent mapping+cath platform. Congrats to @ManningerMartin+entire EP Team #UHC_Graz!

What a great meeting #RIO, what an honor to contribute. Fluoroless PFA is straightforward and worth it. Thank you for the invite @Drdevignair @RIOCongress @radcliffeCARDIO @drjohndayMD

[Vanessa Pittar | EP ABBOTT @VanPittar]

Happy to share our progress at Abbott Electrophysiology!

We've reached three significant milestones today:

* Enrollment for the global IDE of Abbott's Volt™ PFA System has been completed ahead of schedule.
* The global FOCALFLEX trial is now in progress for Abbott's TactiFlex™ Duo Ablation Catheter, Sensor Enabled™.
* The Advisor™ HD Grid X Mapping Catheter, Sensor Enabled™, has received clearance from the U.S. Food and Drug Administration.

Congratulations are in order! Every year, AdventHealth Porter honors a well-deserving physician with the Physician of the Year award. This year, Dr. William Choe, one of our world-class electrophysiologists, was given this title. Salute!

The value of ICE in epicardial VT ablation.

1. Ensure epicardium dry before ablating to ensure optimal lesion delivery.

2. Understand scar and substrate in three dimensions.

3. Monitor for complications during access (visualize wire course) and throughout case (bleeding).

[Daniel Alyesh @DanielAlyeshmer]

Fluoroless PFA #Farapulse pearls (after achieving optimal safety and efficacy):

1) ICE guidance key for contact, left sided ICE especially for right sided veins.

2) Wire tracking.

3) Mapping visualization of catheter confirmation.

4) Projection mapping.
