On Sunday, 30 Mar, during #EHRA2025

@HermansBJM & @Farnir_Florent & @NorupJulie will present translational data on #PFA from our group 🙂

In the first poster session: 08:00 - 18:00
- Tailored pathway for focal #PFA in complex AF cases
- Visualization of focal #PFA lesions in MRI

Moderated ePosters 1: 13:30
- Effects of epicardial #PFA on ganglionated plexi

Would be great to see you there! 🙏

🆕📰New paper online

A novel algorithm to visualize repetitive atrial activation patterns during AF validated using detailed 3D modelling of AF.

🔜 Clinical feasibility with real world human data

We introduce composite maps—a novel algorithm for visualizing atrial conduction activity, with a focus on #AFib. 💻🔬

[Dominik Linz @Dominik_Linz]

#EPeeps

Patient with moderate to severe atrial cardiomyopathy…
(See #EHRA_ESC consensus statement:
https://t.co/oRcGUZ3R6X)
- LA dilatation
- Left atrial tachycardia and “pre-AF” (short runs of irregular atrial activation)
- low voltage areas anterior/septal

First:
Ablation of the focal atrial tachycardia (one application of focal PFA (Galaxy/Cardiofocus, 25A) -> non-inducible

Second:
WACA and anterior line (to prevent atypical flutter as a result of ATach and to prevent the progression to clinical #AFib) -> first pass.

True advantage of combining powerful focal monopolar biphasic PFA with state of the art mapping systems!

[3/3]‼️A considerable interpatient variability in optimal IIR thresholds introduces an underrecognized clinical challenge!

A 'one-size-fits-all' IIR threshold may not be feasible as it could lead to overestimation or ablation scars in some patients and underestimation in others.

[Ben JM Hermans, PhD @HermansBJM]

🆕📰 Online now! 🧵 [1/3]

We systematically determined the optimal LGE threshold for detecting atrial ablation scar in dark-blood LGE CMR.

[2/3] Bipolar voltage maps were compared with IIR.

ROC analyses were employed to determine the optimal IIR threshold for LA ablation scar (≤0.15 mV).

Median optimal IIR threshold was 1.09, with an average sensitivity of 0.73, specificity of 0.75, and accuracy of 0.71.

🆕📰Our algorithm can automatically and reliably align pre-procedural cardiac images (CT/MRI) with anatomies acquired during ablation procedures.

This enables multi-modal characterization of the LA🫀

🆕📰 Online now!

Our study reveals that the supine-standing test does not outperform a baseline QTc in diagnosing LQTS.

However, it may still have value in arrhythmia risk assessment within individual patients.

New paper! Composite Mapping of Repetitive Atrial Activation Patterns during #AF by @ozanozgul ESR5 of the consortium, et al.

This paper emphasizes the potential of composite maps in analyzing RAAPs, highlighting the role they play guiding ablation procedures for #AF management.
