#EPeeps how can we recognize,if the potential in LSPV is LAA farfield,or a signal from PV?Look at the separation of potentials during distal CS pacing! @evgeny_lyan @ThomasDemming #fellowsfirst #CardioTwitter #FOAMed

Check out our #EP_Kiel published case report in @HRS_CaseReports on RA- to LV Access Guided by CT merged with 3D Mapping for VT Ablation in patient with mechanical aortic and mitral valves!

Right Atrium-to-Left Ventricle Access Guided by Computed Tomography Merged with 3D Mapping for VT Ablation in a Patient with Mechanical Aortic and Mitral Valves @veramasloo @evgeny_lyan @CKuehl2015 heartrhythmcasereports.com/a…

Bipolar ablation for VT does not have to be on the septum… @veramasloo ablating between endo and epicardium. @HRS

Always wondered how to map VT by stimulation? Very nice example by @ivroca on s1s2s3. Sucessively shorter coupled stimuly that lead to slower conduction and uncover functional block. See how both the absolute and relative delay increase depending on substrate.

📢LBCT ASCEND CSP #HRS2026 ( Simultaneous pub @hrs_journal) @rdschaller @Drdevignair @pvijayaraman1 @HRSonline #SciComms *⃣Another step toward true physiologic ICD therapy: 👉 A purpose-built, stylet-driven CSP ICD lead by Abbott for LBBAP ➡️Prospective, global IDE trial (n=205) • Implant success: 98.5% • LBBAP achieved: 99% (86% true/likely LBB capture) • Primary effectiveness: 94.6% (exceeded 80% goal) • Stable thresholds sensing at 3 months ➡️Defibrillation performance (critical for ICD adoption): • 100% DFT success • 92.5% terminated with single 20J shock 👉 No compromise in shock efficacy despite septal lead position ➡️Safety signal: • 97.5% complication-free at 3 months • Events included: – 2 lead dislodgements – 1 septal perforation (LV entry, required lead removal) – 1 helix mechanical failure – 1 drop in R-wave amplitude ➡️Clinical Implication: ✴️This is the first dedicated, stylet-driven bipolar ICD lead engineered for CSP, specifically modified for septal/LBBA implantation ✴️Potential to enable physiologic ICD or LOT-CRT ⚠️ Caveats: • Single-arm (no RV lead comparator) • Short follow-up (3 months) • Operator-dependent CSP success • Unknown long-term durability, extractability, and TR impact heartrhythmjournal.com/artic…

Happy to be invited to discuss the Proton late breakers with Dr. Lloyd and @KarimBenali42. It’s different to photons as it delivers right to the spot. Looking forward to more proton data.
