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

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

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.
