What actually "looks good" on ICE:

#ViewFlex Left Atrial imaging @EPS_PDX

Training @MRazminia

Sponsored @AbbottCardio

Complemented #EnSiteX PFA Visualization & Contact Index software.

A post PFA induced tachycardia, entrained at downstream electrogram, with long upstream capture (>75%, seen on splines) confirmed #Reentrant mechanism & circuit participation.

[Jordan Hemmen @jordinarymaps]

Despite multiple PFA applications, unable to achieve anterior block for mitral flutter. Epicardial voltage with peak frequency emphasis highlighted RF target. Lateral splits seen after first TactiFlex application.

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.

The notorious papillary muscle PVC. Originating from lateral aspect of the pap, these bigeminal PVCs were eliminated during the first RF session with the help of the tried and true PDX method.

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 never before.

Some features that stood out to me

🔹 ICE Integration with Grid and FAM Mapping - Real-time visualization that aligns perfectly with 3D GridX and FAM maps. This precision ensures more efficient targeting of critical anatomy, improving procedural accuracy.

🔹 Smooth Transition to the Left Atrium
Despite its softer shaft, the ViewFlex X SE provided excellent maneuverability and control, allowing smooth navigation to the left atrium while maintaining consistent imaging quality.

🔹 Maintaining Outstanding Image Quality
For those of us who’ve always trusted the ViewFlex ICE platform for its superior imaging, this new catheter doesn’t disappoint—it adds seamless integration without compromising clarity.

Premature His Bundle Complexes distinguished AVRT and AVNRT with 100% Specificity and Sensitivity irrespective of location.

A simple & intuitive maneuver.

PHC delivered 42 msec ahead of HIS, perturbed A1-A2 by 15 msec = AVNRT.

Prior PVI and PWI. Narrow channel of slow conduction on the roof identified by #HDGrid. Entrainment yields a return interval of 0 ms; the roof is in this atypical flutter’s circuit. #Entrainment #PMA @bmetzlerEP @madiwcEPdrop @EPS_PDX

Clinical PVC mapped to moderator band via continuous score mapping with a correlation of 96%. The PDX technique was employed to project points to endocavitary structures, enabling precise identification and visualization of the ablation target. #PMA

Hx PVI + PW, presenting with typical AFL.

CTI & re-isolation of LPV performed.

During left atrial post mapping, induced 230 msec tachycardia.

Inadvertently terminating during left atrial mapping, though incomplete, passively activated.

Unable to reinduce.

Right Atrial, S3 Protocol was performed.

Increased ectopy during ablation at this AT’s site of earliest activation, demonstrating irritation of the tachycardia’s focus @JaylynnMariePDX @EP_EmilyS #PMA

S3 protocol, once again proved valuable in identifying ablation targets within this complex ischemic substrate.

Impressive decoupling of EGM's, otherwise missed with fixed S1 mapping.

The novel S3 whole-chamber protocol for assessing the ventricular functional substrate is feasible in 85% of patients, allows better identification of targets for ablation, and might improve VT ablation results. https://t.co/GNP772RseM

An untouched atrium, presenting with concordantly positive p-waves.

A Reset ExtraStimulus Map helped limit ablation beyond PVI, despite multiple areas of deceleration and potential participating circuits.

[Isabel Mauck @isabelmauckEP]

Alternative form of entrainment with a sensed extrastimulus beat from a site of late activation. The paced wavefront travels orthodromically, captures atrial EGMs upstream, and resets the tach. The RA lateral wall is within the tach circuit. #PMA #REM
