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.

Enjoyed assisting with some workflow and technology improvements in FIH trials of novel Viewflex X ICE catheter from @AbbottCardio -- we performed ablation of PVC from suspected intramural site with RF to septal RVOT and adjacent ASOV. Will be curious to see what @dhakalbish

Monday started with First-in-Human Use of “ViewFlex X SE” ICE Catheter with @AbbottCardio I've always loved using the ViewFlex ICE for its exceptional image quality, but now with seamless ICE integration into Ensite X, this is a total game-changer that enhances precision like

Patient Hx 3 yrs post Cryo PVI & CTI. 3 months post PFA of posterior wall. Presented in 340 ms tachycardia. #HDGrid showed scarring with slow conduction through left atrial roof and floor. Termination at isthmus, confirmed with entrainment, with #TactiFlex. @LydTrautEP #PMA

Prior to start of the case we predicted critical isthmus to be originating from anterior scar in LA based on morphological similarities w/ NCC AT. ICE nicely shows relationship between flutter term and cusps @forkknifecab_EP #PMA

Weren’t able to achieve block with a non irrigated catheter so switched to #TactiFlex. Satisfying when you map a leak and get it right away. Even on JUST a CTI line. #PMA

Hypnotizing local reentry in a stable post-maze tachycardia, with full CL seen on HD Grid. What is the cause/substrate for this type of AT after a maze procedure? @AbbottCardio #EPeeps Case with Dr. Smriti Banthia in Sarasota, FL.

Always wary when EKG shows right anterolateral for WPWs, but even with challenging stability, we were able to successfully ablate this AP with #TactiFlex. Antegrade map on left and V pace map on right in both images. #PMA

Combo VT and PVC case. NICM-fascicular (non-Belhassen)) VT exiting from LAF, non indicible after targeting earliest exit. Also summit PVC successfully sandwiched between RL ILT and LCC. Great mapping @georgecrowell #EPeeps
