#EHRA25 was again a great meeting in Vienna. Proud of the good representation of Maastricht with even people missing on the photo… @MaastrichtUMC @CARIMMaastricht @UyenChauNguyen1 @Dominik_Linz @EHRAPresident @BetzKonstanze @GawalkoMonika @UliSchotten

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! 🙏 @kvernooy @JLuermans @UliSchotten @JacopoImberti @BA_Mulder @veramasloo @micaela_ebert @DrAnthonyLi @HenrikeHillmann @netta_doc @nlcabanillas @karl_thien @ChristianHeeger @GiulioConte9 @FraSantoroMD @AndyZhangMD @DavideMei93 @marcovitoloMD @Mel_Gunawardene @jongichun @atulverma_md @PrashSanders @chris_sohns @jskoruth #EHRA_ESC @simovicst @EHRAPresident @DavidDuncker @ManningerMartin @StavrosStavrak1

@UyenChauNguyen1 @MirekNavratil1 @edobressi @JLuermans @kvernooy The sample frequency should be 250Hz for these routine ECGs

@MirekNavratil1 @edobressi @HermansBJM @JLuermans @kvernooy Conventional 12 lead (clinical) ECGs from three centers. We will have to check in Matlab, but I think usually <200 Hz.... always wondered to what extent UHD dyssynchrony measures are affected when incorporating normal frequencies

Our Europace paper is now online <3 LBBAP leads to a more synchronous repolarization acute and permanently and avoids the acute increase of dispersion of repolarization as seen after BiVP. @edobressi @HermansBJM @JLuermans @kvernooy academic.oup.com/europace/artic…

🆕📰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 tinyurl.com/yuy27zst @Dominik_Linz @CARIMMaastricht #EPeeps

#EPeeps Patient with moderate to severe atrial cardiomyopathy… (See #EHRA_ESC consensus statement: academic.oup.com/europace/advan…) - 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! @MaastrichtUMC @CARIMMaastricht @kvernooy @JLuermans @Farnir_Florent @BiomedUCPH

[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.

[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.

🆕📰 Online now! 🧵 [1/3] We systematically determined the optimal LGE threshold for detecting atrial ablation scar in dark-blood LGE CMR. @MirandaBijvoet @Dominik_Linz @kvernooy @CARIMMaastricht @MaastrichtUMC #EPeeps tinyurl.com/3cs3256p

🆕📰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🫀 @Dominik_Linz @UliSchotten @MirandaBijvoet @kvernooy tinyurl.com/ycycmjj4

🆕📰 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. 🧐tinyurl.com/32j5ysua @JAHA_AHA @Dominik_Linz #epeeps
