Captured a beautiful mid-diastolic signal during VT mapping with #HDGRID There’s nothing more satisfying than pinpointing the critical isthmus in real-time. 🎯 #ablateVT #EnsiteX #AbbottEP #EPeeps

7/10 – PFA for Ventricular Arrhythmias Using Pentaspline Catheter @Dr_Santangeli @EP_mom1 *⃣Cleveland Clinic’s first U.S. series of VT/PVC ablation using the FARAWAVE pentaspline PFA catheter. 🌟Key findings: ➡️11 patients (mostly ischemic scar VT). ➡️PFA used for large-footprint substrate modification or after acute RF failure. ➡️100% acute non-inducibility; no procedural complications. ➡️Recurrence modest over 6 months. 🧑‍🎓This early U.S. experience shows PFA is emerging as an alternative/ supplemental VT Ablation tool. heartrhythmjournal.com/article/S1547-…

So I mapped this AT the other day, and I don't think I've ever seen a focal AT coming from this exact spot before. Patient had tons of PACs and runs of AT, all sharing the same morphology. Could it be Bachmann's Bundle insertion? @jacabreracardio @DrRoderickTung #EPeeps

It’s amazing how far technology has come, but I’m sure that anatomy and ECG will never go out of fashion in electrophysiology. Very didactic images in this month’s @JACCJournals Understanding Cardiac Anatomy and Imaging to Improve Safety of Procedures: 12-Lead Electrocardiographic Anatomy. Bradfield et al. jacc.org/doi/epdf/10.10…

Paraseptal focal ATs arise from diverse but closely related anatomical locations. There is no site from which ablation is consistently successful. Although some are indeed perinodal & accessible from the NCC, others arise from adjacent structures. jacc.org/doi/10.1016/j.… #JACCCEP

We published a novel AT mechanism: localized re-entrant atrial tachycardia involving the coronary sinus (CS-AT). Rare (~1%), mimics focal AT, requires CS mapping. Therapy: LA–CS ablation or VoM ethanol infusion. 🔗jacc.org/doi/10.1016/j.… #EPeeps #CardioTwitter #JACCEP

Maybe we can try "Reset AT" to localize the circuit and minimize ablation lesions😀 ↓ link.springer.com/article/10.100…

Atropine unmasks functional EGM fragmentation in GPs areas, refining targets for selective cardioneuroablation in vagally mediated syncope #AHAJournals #Epeeps doi.org/10.1161/CIRCEP…

Great case of redo VT with investigational Tactiflex dual energy catheter on a patient with intramural substrate and previously failed 3 ablations including alcohol ablation. Patient was in incessant slow VT, entrained and terminated at the isthmus site with second PFA.

The #UHF-ECG overlay with the averaged 12-lead ECG signal has become a popular tool lately - generating numerous "aha" moments with question mark morphologies.

By unmasking slow conduction gaps, nearby and overlap pacing do much better than left appendage pacing for roof line block validation @EPBordeaux #AHAJournals #Epeeps ahajournals.org/doi/10.1161/CI…

Periaortic VT substrates are increasingly common amongst NICM patients, yet extremely hard to diagnosis with imaging.
