Can we use PFA selectively to treat the myocardium and spare the conduction system? #ablateVT #Epeeps

An excellent start to the Complex Mapping and Ablation Workshop at Karolinska University Hospital in Stockholm, with complex VT cases and practical insights shared throughout the day. Directed by Dr Finn Akerstrom (@finnakerstrom) with K’s great team, Dr Peter Karl Jacobsen and Dr Javier Moreno

Comparison with our SUPPRESS-AF trial (Nat Med. 2025;31:1661–7):
Single-procedure arrhythmia-free rates
(LVA ablation vs PVI alone):
✔ SUPPRESS-AF: 61% vs 50%
✔ IDEAL-AF: 62.7% vs 31.8%
Why was the recurrence rate so different in the PVI-alone arm between the two trials? 🤔
🧵 Presented today at #ESCCongress:
Among patients with persistent #AtrialFibrillation and significant low-voltage zones identified by electroanatomical mapping, adjunctive low-voltage zone ablation added to pulmonary vein isolation improved arrhythmia-free survival at 12 months vs pulmonary vein isolation alone.
Benefit was observed after 1 or 2 ablation procedures and without antiarrhythmic drugs, supporting a substrate-guided ablation strategy in this population.

Free read at @JICE_EP. There are many variables to consider for PFA. We examined one parameter (interpulse delay) and found that lesions were larger when the time between pulses was increased, regardless of total energy delivered.

RCT: Intracardiac echocardiography is non-inferior to transesophageal echocardiography for thromboembolic prevention in atrial fibrillation ablation, with added benefits in safety, efficiency, and patient comfort.

Periaortic VT substrates are increasingly common amongst NICM patients, yet extremely hard to diagnosis with imaging. Congrats @NaohikoSahara on leading our group, showing yet another value proposition for ICE. @JACCJournals. #ablateVT

#AbbottProud to see the first-in-human use of our #ViewFlexICE, Sensor Enabled* and #EnSiteEcho technology!
Thanks to @Drdevignair for your valuable insights and partnership.

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.
