Patient came in for RV substrate evaluation after prior failed #ablation. #HDGrid revealed fractionated, late potentials on the RVOT freewall and led to the discovery of a micro-reentrant VT circuit.

Omnipolar is game-changing for automated ILAM approach. New(L) vs. old(R) auto annotation display without any manual annotation. Yet another localized periaortic VT substrate from LMNA, with diastolic 🍽️ buffet during VT within sinus rhythm deceleration zone. @AbbottCardio
3 prior ablations (2 endo,1 epi-endo) flown from out-of-state ✈️ to our team @UAZmedphx, transmural inferior MI. Large macroreentrant epicardial circuit that required multiple ablations due to intramural component inferred by progressive slowing with each application. #ablateVT
Ensite X + omnipolar technology (HD grid) displaying a scar-related small reentry, StaMP-mapping... 36 channels on a single spot, full ATCL... more data 👇 #Epeeps@AbbottCardio@EF_Cardiaca@DrRoderickTung
First VoM ethanol ablation at Spectrum Health today! Flutter termination with alcohol (so cool!), with some RF touch up at annulus. Big thank you to @HiroshiAshikaga for proctoring, mapping support by @HankoRyan, and our EP lab staff. @AbbottCardio, @SpectrumHealth, #EPeeps
Focal #SVT easy to map/terminate with #HDGrid w/ -30 ms pre P ablation; but functional character of Crista anisotropic conduction fun to see for intracaval conduction, vs. 46 ms to go 6 mm transverse b/w splines in SVT #EPeeps#cardiotwitter@AbbottCardio Map @nmendoza529#MedEd
NICM EF 15 sent for recurrent VT, prior substrate ablation, Amio/Mexitil side effects. Unstable MMVT to PMVT in 4-6 beats with multiple defib. #ILAM to target deceleration zone elimination, which correlated to LPs-Low Voltage. 3 mo no VT off AAD #AblateVT#EPeeps@DrRoderickTung
