Looking back over this case and had to share these signals. #ILAM #decelzone @JRWinterfield @DrRoderickTung

Paying about $7,500 a year into social security from age 18 to 67 gets you roughly $3,200 a month in retirement.
If you invested that same amount in low-cost mutual funds, you could end up with around $32,000 a month instead.
about 10 times more.
Social security is a scam.

Cardioneural ablation continues 🫀
Roderick Tung reviews a sustained heart rate response, then tests SNRT after one treated region to assess the next step.
Real-time physiology guiding ablation.

Cardioneuroablation for Ictal Asystole new in JACC EP- Our international multicenter case series of 12 patients who underwent CNA for ictal asystole. Grateful for @andresenriqueza mentorship on this project and to all our coauthors who made it possible! jacc.org/doi/10.1016/j.jacep…

Can balloon technology do more than PVI?
Case led by Arian Sultan and discussion with Roland Tilz.
Selective electrodes, controlled overlap, and targeted energy delivery help extend ablation strategies beyond the veins.
Here they highlight a smarter way to personalise lesion sets.

is EPICARDIAL ABLATION for flutters unnecessary in PFA times?... unfortunately we don´t think so... here we show an epicardial bridging after an anterior mitral line despite stacking RF (red) PFA (blue) below. Epi RF ablation worked
(PVI PWI were performed right before, for persistent AF)

In Chicago for #HRS2026 and I couldn’t be more excited. This year’s conference marks the first time that HRS attendees will get to fully experience the next generation of PFA: #VoltPFA System.
Come see it for yourself tonight at the Field Museum! tinyurl.com/bdd2hu2a

Superb #VoltPFA symposium at #EHRA26! Thank you, panelists, for covering PVI procedural workflows, first-gen limitations, concomitant strategies, and the benefits of integrated tools like EnSite Echo. Great session.

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.

Add EnSite to your ablation approach with EnSite Echo on #EnSiteX.
Immediate visualization and model creation with #ViewFlexICE allows for identification of key structures prior to mapping catheter introduction.

🧵Our scar-related VT ablation today!
#ILAM lines of block (LOB) mapping with Ensite. Beautiful substrate definition. Ablation targeted deceleration zones & LOB in basal/lateral LV.
✔ No VT induction attempted
✔ Substrate-only strategy
✔ Mapping entirely in sinus rhythm
#Epeeps #Cardiotwitter! Always grateful to work and learn alongside @epdocwidguitar⚡

#EPeeps — can @AbbottCardio #VoltPFA be used safely in the RVOT?
Following PVI/PW #AFib ablation, PVCs were mapped to the RVOT. The Volt catheter tracked easily into the RVOT from the Agilis sheath left in the RA and safely and successfully ablated the focus. @martinezcarl3D
