Thanks to all faculty and attendees who navigated some significant travel challenges to participate today!

Was another fantastic Epicardial Training course hosted by @UChicagoMed for the first time. Hopefully was a valuable learning experience.

For those that missed out on attending the training course this time - we will be announcing a second course
this year soon… stay tuned!

🧵1/ Trigger vs Substrate in Purkinje VF — which strategy wins?

#HRS2026 data comparing trigger vs substrate-based Purkinje de-networking provides first direct answer.

Purkinje-mediated VF arises from:
🎯Discrete PVC/fascicular triggers
🌐Diffuse abnormal Purkinje substrate

👉 Key question: target the trigger… or the network?

Excited to share this new book on Cardiac CT!
Forever grateful to Dr. Braunwald who asked me to write this and for his guidance and mentorship along the way. While we are mourning his recent passing, I will treasure all the conversations I had with him on #CCT and #Prevention

🧵1/ Another #HRS2026 #JACC data on Purkinje De-Networking (PDN) for recurrent VT/VF!

MMVT patients + prior polymorphic VT/VF, adding PDN during VT ablation improves outcomes.

Results at 12 months: VT/VF-free survival:
🔰81% PDN+VT vs 49% VT ablation alone
🔰Absolute difference: 31.6%
🔰HR for recurrence: 0.29 (p=0.02)

Multicenter data on Purkinje de-networking for VF

⚡️Substrate-based ablation → greater freedom from VT/VF
⚡️Trigger-based ablation → lower risk of conduction injury

Balancing efficacy and safety remains key.
