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

Cohort 3 of the ViewFlex X ICE First-in-Human study reflects what innovation should look like. Continuous evolution with meaningful clinical impact. With the updated EnSite X v6.1 software, we are seeing tangible workflow and imaging advancements: 1. Improved contour editing workflow 2. Auto geometry capture with continuous catheter rotation from both the right and left atrium 3. Automated structure labeling on snapshots 4. Pre–E-fields for voltage mapping, providing valuable guidance for catheter positioning prior to energy delivery These enhancements are not just incremental, they represent a step forward in integrated mapping and PFA with real-time imaging synergy. Proud to contribute to this work at @ARGJonesboro , & @StBernards , advancing imaging, integration, and the future of electrophysiology. @AbbottCardio @AbbottNews #Electrophysiology #PFA #CardiacImaging #Innovation #MedTech #EnSiteX #ICE #ArrhythmiaResearch

Speed is impressive… but simplicity might be the bigger win. HD Grid X pre → Volt PVI → HD Grid X post Volt PVI below ↓ #EPeeps #PFA #EnsiteX @AbbottCardio

Great tech and team! Check out booth 219!

Impressive safety & performance results for both #VoltPFA and TactiFlex Duo presented at #AFSymposium2026. Thanks to Prof. Deisenhofer & Dr. @atulverma_md for sharing these milestones. 🔗 Volt AF‑IDE: lnkd.in/g7B2hXAS Safety: bit.ly/44YCnzi #AbbottProud

First-in-Nation: Integrating ViewFlex X SE ICE with VOLT PFA This week started with a meaningful milestone at St. Bernards Healthcare (Jonesboro, AR) — first-in-nation combining Abbott’s ViewFlex X Sensor Enabled ICE with the VOLT PFA platform. This builds on our prior experience with: • FIH clinical trial use of ViewFlex X SE • Post-FDA VOLT PFA cases as part of the VOLT LMR What stood out was how well imaging + mapping + energy delivery functioned as one ecosystem in a zero fluoroscopy / zero contrast workflow . Key takeaways 🔹 ICE integrated into EnSite X for real-time anatomic confirmation during PFA 🔹 Safe ICE-in-LA workflow and transseptal planning that reduced unnecessary manipulation in small LA anatomy. Integration helped support transseptal decision-making up front—optimizing trajectory and reducing unnecessary catheter manipulation in small LA anatomy. 🔹 Quick LA shell creation to confirm ridge/posterior wall/carina geometry early 🔹 Small atria lesion strategy: integration helped us decide tighter antral lesions vs intentionally addressing a posterior “critical isthmus” when the posterior corridor was inherently narrow 🔹 During VOLT delivery: very low microbubble visualization on ICE and no clinical hemolysis observed VOLT workflow highlights: single-catheter mapping/pacing/ablation, impedance-based contact visualization, balloon-in-basket (8 splines), selective electrode delivery; PVI ± PVI+ as clinically indicated (GA used). Grateful for the St. Bernards EP Lab team and the Abbott clinical support team. #ViewFlexXSE #VOLTPFA #FirstInNation #ICE #EnSiteX #ZeroFluoro #ZeroContrast #EPWorkflow #Innovation #epeeps @StBernards | @ARGJonesboro I @AbbottNews I @AbbottCardio

Exciting start to the year with Dr. @DJ_Lakkireddy, @Drdevignair & Dr. @srissundaram completing the first U.S. cases with #VoltPFA. Thank you for your partnership, and to team #AbbottEP for your support of this milestone. Learn more: voltpfa.com #AbbottProud

Proud to share that we completed our first and some of the first cases in the nation post fda approval of the Abbott VOLT Pulsed Field Ablation (PFA) system at St. Bernards Medical Center in Jonesboro, Arkansas as part of the #VOLT LMR, following VOLT’s FDA approval in late December. What stood out in our early experience: - Zero fluoroscopy workflow in these cases
- PVI, with additional workflow as clinically needed
- Very low microbubble visualization on ICE, and no clinical hemolysis observed in any of our cases We also appreciate the platform design elements that support efficiency and precision:
- Balloon-in-basket design (8 splines) that conforms to anatomy and supports targeted lesion sets 
- Real-time contact visualization (impedance-based) for lesion tracking 
- Single-catheter , zero exchange workflow enabling mapping, pacing, and ablation while minimizing catheter exchanges 
- The ability to customize energy delivery by selectively delivering from electrodes in good contact Our cases were performed under general anesthesia, and it’s encouraging that PFA workflow characteristics may support future pathways that reduce reliance on GA in selected patients. Huge thanks to our incredible St. Bernards EP Lab team and the outstanding clinical support team from @AbbottCardio. Teamwork made this LMR launch a success.

A meaningful step forward for Abbott EP: FDA approves our Volt™ Pulsed Field Ablation (PFA) System for AFib treatment. Read more: lnkd.in/gYqbiXPX Safety: voltpfa.com #AbbottProud #RevoltAgainstTheOrdinary

Last week, I had the privilege of attending GIEPC in Munich. It was an honor to hear EPs across Europe discuss, debate, and demo their evolving PFA workflows (contact, conscious sedation, beyond PVI) and methodologies to tackle AF & VT. #AbbottProud

More Global IEPC highlights: excellent mix of EP leaders demonstrating their Volt PFA workflows & evolving VT science w/ advanced mapping. Thank you to the many physicians who made this such a meaningful educational program. #VoltPFA #AbbottProud #AbbottEP

Two dynamic days in Munich with global EP leaders exploring the latest in Electrophysiology—from Volt PFA workflows to VT mapping innovation. Grateful to our course directors, faculty, and Abbott Global Education team for making it all possible. #AbbottProud #AbbottEP #VoltPFA

Awesome first half of 2025 at Abbott EP. From elevating PFA workflows with EnSite Contact Index to launching Volt PFA in Europe, there is amazing momentum heading into the rest of year. Grateful to the many teammates & friends who’ve made these milestones possible. #AbbottProud

Thanks to Dr. @atulverma_md for sharing his knowledge on PFA lesion optimization for efficacy and safety. #ContactMatters #NotallPFAisthesame #HRS2025 #AbbottProud

As the conference wraps, I want to again credit this team. Since Friday, our clinicals have led nonstop demos across a huge variety of disciplines (EnSite Contact Index, Agilis 13F, Integrated ICE, Perclose, HDGX, etc) and have done so beautifully. Thank you for a great #HRS2025.

One of my favorite things about Abbott is the sheer number of life-changing solutions our teams offer. Today, there was no better demonstration of that than the joint presentation by @Drdevignair & @siddmann. #AbbottProud

Incredibly #AbbottProud to join a packed house for a live demonstration of our next-generation tech at today’s PFA Summit. A great start to what is sure to be a great #HRS2025.

Excellent PFA Summit finale by @josoriomd on how new tools expand the workflows possible with PFA. Thank you to the many #EPeeps who made this program a powerful kickoff to #HRS2025!

Day 1 at #HRS2025 off to a great start with our annual the EP Fellows program. Always one of my favorite examples of clinical collaboration, featuring hands-on learning btwn our mappers and future EP leaders. Next session at 2pm next to Rhythm Theater 2.

Bonus #EHRA2025 Highlight: After hours at the convention, David Smith used #EnSiteConnect to remotely map his team’s first Contact Index case back in the US. Best-in-class support from Vienna to Alabama. Amazing. #ContactMatters #AbbottProud
