3 illustrative points from a complex epi VT ablation:
1) Sinus wavefront discontinuity lines form fixed lines of block contributing to VT circuit boundaries. Here, pacing across the WADL ~5 mm away from a perfect VT pace map creates an entirely different QRS and stim-QRS

PVC with CARTO V8 bracketed in a septal perforating branch of AIV. Multipolar mapping with the OPTRELL shows earliest site in LVOT displayed with LAT Velocity Vectors. @Davilandre@TimothyMaherMD1@rdangeloMD @BiosenseWebster #epeeps
First EU 🇪🇺 cases yesterday with Carto V8 @CHURennes 🇫🇷!
- New Automatic Pattern Aquisition for PVC ablation
- Lat Velocity Vectors for VT ablation
- AI is now in Carto with automatic Fragmented annotation tools
Thanks @BiosenseWebster @TachyDestroyer@adebost
Successful launch day at @SIUHhospital of the #Optrell mapping catheter. Grey Discs on isolated posterior wall for a Persistent Afib then next case showed power of Real time LCVs during focal activity in an AT! Thanks to @ValayParikhMD !

New research from the VT Center at @BidmcCvi in collab with @BIDMCRad:
Does LV wall thinning found on cardiac CTA predict functional substrate mapping targets for patients undergoing VT Ablation?

Nice scar VT with Jon Waks at @BidmcCvi. Crisp extreme late potentials and split LPs using the smaller Optrell 36 in an area of septal scar during RV-pacing using Late Activation Mapping in a patient with non-infarct cardiomyopathy. #ablateVT
Open window RA septal pathway with #OPTRELL. A fun use of the local conduction vectors to localize this accessory pathway with #CARTO @BiosenseWebster

Congratulations to winner of the Mark E. Josephson Abstract Competition & Innovation Award @TimothyMaherMD1 from Beth Israel Deaconess Medical Center for his abstract Testing the Safety and Behavior of CIEDs During Cremation @VTSymposium#Epeeps#cardiotwitter
Great @PennMedicine EP grand rounds with @Davilandre - voltage independent substrate modification approach with no VT induction and same day discharge @PennEPFellows
