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.

So I mapped this AT the other day, and I don't think I've ever seen a focal AT coming from this exact spot before. Patient had tons of PACs and runs of AT, all sharing the same morphology. Could it be Bachmann's Bundle insertion? @jacabreracardio @DrRoderickTung #EPeeps

Voltage with peak frequency >250hz and LOB seen in RV pacing ILAM map. @inheartmedical scan correlating wall thinning with our area of interest.

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

[Bishnu Dhakal MD FHRS @dhakalbish]

Great case of redo VT with investigational Tactiflex dual energy catheter on a patient with intramural substrate and previously failed 3 ablations including alcohol ablation. Patient was in incessant slow VT, entrained and terminated at the isthmus site with second PFA.

[Dr. Devi G Nair @Drdevignair]

First-in-Human cases  with ViewFlex™ SE + EnSite™ X v5 at #ArrhythmiaResearchGroup Group and St. Bernards Healthcare as part of ViewFlex SE Trial.

Pushing the boundaries of EP workflows with the first clinical use of the @AbbottCardio ViewFlex™ SE ICE catheter, now paired with AI-assisted map creation, Grid Mapping, and real-time Contact Assessment using Farapulse and PulseSelect PFA systems.

Some of the features that caught my eye:
    Physician-ready geometry with EnSite Echo
    Simplified ICE navigation to stay focused on therapy
    Single-handed deflection via auto-locking mechanism
    Color-coded deflection indicators for intuitive control
    Softer, more stable catheter with enhanced torque response
     Sterile tip-to-connector (no sterile bagging)
     Single catheter cable = less clutter, more efficiency
    Contact is critical in PFA — and the new Contact Index on EnSite X v5 lets you validate contact instantly and tag lesions appropriately.

Powered by AI. Backed by precision. Designed for EPs.
A simplified, smarter, and safer workflow is best workflow ever.

A mappable VT meandering through WaDLs / Lines Of Block.

Intuitive S3 Protocol discontinuities, 98% Correlation Score, and VT activation maps, supported a thoughtful ablation strategy.

First experience with Volt catheter in A Coruña, 2 PVI cases + CTI line made with PFA. Congratulations a everyone and thank you for the support to @AbbottCardio @ritmo_SEC @PabloFdezdeAspe @RVazGar

[Kevin Brady @Hapa_EP]

First time mapping a Farapulse PFA case with Abbott's new 3.1.1 Contact Index software. Petals 🌺 light up in blue 🩵 when making good contact with tissue and turn gray when floaty. Good adjunct to ICE! Worked well with a local impedance threshold 10-12% above baseline. #EPeeps

[Aaron Matthews @AMatthews0]

Dramatic RV paced ILAM. Multiple breakouts through diseased septum followed by activation of a narrow corridor within 2-3mm of WT on @inheartmedical imaging. Case by @dhakalbish of @MUSC_EP. More info in comments.

[Aaron Matthews @AMatthews0]

Multiple VTs produced by dense lateral scar. Procedure performed by @ChauVoMD of @MUSC_EP

[Kevin Brady @Hapa_EP]

Tough right anterior WPW case. Found a good fused egm, and got it multiple times from below, but contact was unstable and the pathway kept coming back. Finally we got IJ access, and take a look at the rooster head 🐔 ablation egm just before burn ❤️‍🔥. #EPeeps

#ContactMatters

Provide EnSite to your PFA delivery strategy with #EnSiteX. Contact index software allows for tissue contact feedback with intuitive visualization on each spline.

How would #ContactIndex impact your PFA workflows, #EPeeps?

VT storm ablated with a first burn term over the weekend thanks to @JRWinterfield. #GridX with OT near field algorithm allowed for quick and accurate mapping in complex substrate.

Fantastic mapping by @AbbottCardio partner @brysontindal9 on this past Saturday morning to assist a woman with remote anterior MI presenting with incessant slow VT and cardiogenic shock.
