Here is the video of PFA delivered near a LAA occlusion device

Nice example of [left-sided] AVNRT ablation from LA targeting left atrial slow pathway (SP)! 👉If no junctional rhythm induced with ablation at inferior ToK (targeting RIE) or CS roof (targeting LIE) ➡️ think left lateral SP. #EPeeps

🚨🚨🚨 New educational video!!! Temporary epicardial pacing wires after cardiac surgery - troubleshooting and other uses. Oversensing, undersensing, rising pacing threshold, proarrhythmia. Also SVT diagnosis and AT/AFL pace termination! youtu.be/dpVelE8gjOQ

By the way, as we learn about VT entrainment, we also discuss how understanding egm signals in scar helps us with substrate-based VT ablation strategies in sinus rhythm/pacing (!)

Young pt with refractory IST 🚫 RFA due to phrenic nerve proximity ✅ PFA of IST with the @Medtronic PulseSelect system Immediate ⬇️ in heart rate with inversion of P wave axis, chronotropy intact on Isuprel, no diaphragm injury No need for epi access or phrenic deviation!

Atrial functional MR was not taught during my medical school or residency. We need to characterize and understand pathophys collectively.

Hot off the press!🚨 Check out this important work on #VT_ablation post #LVAD: "Mortality in Recipients of Durable Left Ventricular Assist Devices Undergoing Ventricular Tachycardia Ablation" doi.org/10.1016/j.jace… @MihailChelu #EPeeps #AblateVT #MCS #HeartFailure

@chizhangmd Whoa! Congratulations 🎉

Last two VT cases to wrap up EP fellowship! 1. Endo/Epi RFA of lateral substrate in a pt with recurrent MMVT despite anti-arrhythmics 2-4. Bipolar PFA of basal RV/LV in a pt with prior failed VT ablations and intramyocardial substrate; VT termination with PFA!

Doctors don’t believe in extortion. They don’t like being a victim of it either. ABMS MOC has never been proven (independently) to improve patient care or safety, yet its strongman financial tactics are imposed annually on US physician educators solely for the ACGME’s benefit.

Is there any possibility that I could lose this Hyde Park soapbox session to #HRS2024 @EPrystowskyonEP, regardless of which side I take? 🤣

Contact force for the first few seconds at 90W is less important for lesion depth. Keep a light touch for posterior wall lesions when using these settings. @TheSteigasaurus @JorgeERomeroMD @paulzei @nauffal_victor

A new cardiac atlas from Cardiotext coming in May: Atlas of Interventional Electrophysiology. @shivkumarmd @DrRoderickTung Look inside the book: publuu.com/flip-book/3589… cardiotextpublishing.com/electrophysiol…

Nice work from the UC group led by @gauravaupadhyay on further defining LBB. Not just an exercise in academics. Imp for selection of CSP Time to notch in Lead 1 > 75msec looks the best discriminator in a clever analysis Wide QRS due to LBB not the same as wide due to IVCD jamanetwork.com/journals/jamac…

There are many ways to fix the intraseptal lead during LBBAP implant to achieve physiological pacing. Many use two hands. Tips and tricks for a single left-handed technique: 1) Sheath tents RV septum with contrast 2) Advance lead tip out slowly to the point of almost displacing the sheath 3) Right hand fixes the sheath torque using syringe of contrast 4) Rapid rotations to spin the lead between left thumb and index finger- palm up 5) Contrast injection to confirm breaking through the RV endo plane in LAO
