EP Mappers - Bay Area

@AbbottCardio #EPeeps in the Bay Area. Highlighting interesting cases and signals! ❤️🩺

[EP Mappers - Bay Area @EPbytheBay]

Had a great AF Redo case with Dr. Rajan Shah. We mapped two simultaneous flutter circuits using HD GRID: one around the left pulmonary veins, utilizing the posterior and anterior wall, and the other counterclockwise around the left atrial appendage.

Young patient w/ HCM/hypertrophic cardiomyopathy, recurrent VT despite 3 AADs: Amiodarone, Sotalol and Mexiletine. Endo (sinus) & epi (S1) ILAM mapping showed matching isthmus locations. Targeted using bipolar ablation. Active ABL= epi, ground = endo. #AblateVT @atrialappendage

Three for one! Very fun case with Dr. Matt Cain at Adventist St. Helena Hospital

[EP Mappers - Bay Area @EPbytheBay]

AT mapped to the lateral mitral isthmus (Rachel Willis). Distal CS signals preceded all LA signals. Notice signal change as the ablator subselects the vein of Marshall (imp. to 200+ ohms). VOM alcohol ablation terminated rhythm. Case performed by Dr. Cain at St. Helena Hospital

Recurrent septal VT targeted with bipolar radiofrequency ablation, 0.45 NS. NICM, existing CRT, three prior unipolar ablations. Active ablation catheter = RV, ground = LV. VT term with transition to paced QRS

Our inaugural REFINE meeting in South America was an absolute delight! I relished connecting with new friends and had an unforgettable time in Colombia. 🌟🇨🇴

[Natalie Tuck @NatalieTuck8]

87 y/o patient had been in AF for years with several failed DCCVs. After PVI, rhythm converted in to a 330ms mitral AFL using an epi CS connection. Endo HD Grid signals show block, ablation signal in CS shows missing CL. Termination in CS by @MRazminia — finally in sinus 🙌🏼💥

It was great hosting @mike_lean and @Austin_in_EP in Fort Worth to share our PVI workflows!

Right WACA approach can provide opportunities for septopulmonary connections… Observe the reverse 3 with Dr. T in this #MedinboxMonday.

What approaches are you taking for #AFib, #EPeeps?

Successful ablation of this posterior medial papillary PVC! With delivery of RF we induced a flurry followed by suppression. The video in the comment shows post ablation echogenicity, proving lesion formation on the pap! @atrialappendage

[W2 Mappers @GoldenStateEP]

AT originating from the NCC, just a little too close to the His to burn from the RA. Check out the EGMs that show RA and LA dissociation in tach! PAC from HRA fails to change CS and V activation and timing. Sinus rhythm restored after a few burns to this area💥@atrialappendage

[EP in the OC @EPintheOC]

Great morphology match on this LV PVC. What to do when the Pap is in the way? Map it! Earliest spot was at the base of the inferior septal pap. #hdGrid made quick work of it. Mapped and ablated in under 45 min! #OT #EnsiteX #Voxel

[Rajan Shah @atrialappendage]

The very 1st #AblateVT for the @SHC_TriValley community 🚩 @StanfordHealth. Dual-arrhythmia NICM: LsPeAF & >25% mono PVCs/VT refractory to Sotalol/Amio. Epi #HDGrid mapping of PVC via VATS port at time of #HybridAF. EF 20 📈 60% cMRI without AAD at 8 months, ICD avoided #EPeeps

[Rajan Shah @atrialappendage]

@AbbottCardio was so close when they chose a name for their mapping catheter… next time. How we #EPeeps walk out the lab after diastolic buffets and termination #HDGriddy when you get it

[W2 Mappers @GoldenStateEP]

Couldn’t afford to induce so we didn’t! EF drop -> 10% after recurrent hypotensive VT > 22 shocks. Refractory to Sot, Prop, Amio, Lido, Proc. Targeted abnormal Purkinjes + functional substrate (#ILAM). Now home >3 months, Metop only w/o rec #EPeeps #AblateVT @atrialappendage

[W2 Mappers @GoldenStateEP]

Anterior LA pinwheel flutter, spinning around scar from prior ablations. Vectors helped to quickly define lines of block and the path of the circuit! Mapped by @C_Harrison_EP w/ Dr. Raj Shah @atrialappendage! #OT #HDGrid #Fluoroless

[W2 Mappers @GoldenStateEP]

First chance getting to map a concealed LL Pathway with #Omnipolar, #HDGrid, #OWM, #ZeroFluoro! Young Pt in their 20’s now cured with no recurrence of palpitations! Great case by @cbrodt and @50wattdoc Mapping credit to the fabulous Priya!!

[EP Mappers - Bay Area @EPbytheBay]

Very active posterior wall with some activation leakage into the left PVs in this redo AF patient. A successful first pass isolation with roof/floor lines at #StHelenaEP! Abbott mappers: @nschraderEP @RachelWillisEP

[EP Mappers - Bay Area @EPbytheBay]

@Hapa_EP @Hapa_EP we lost pre-excitation after ablating the first pathway, but then had eccentric activation when V pacing!

[EP Mappers - Bay Area @EPbytheBay]

What’s better than one pathway…? THREE pathways! Patient presented with WPW and sustained ORT. We mapped to find a left posteroseptal AP. Following ablation, we still found 2 more pathways all 1.5cm apart! After ablating all 3 APs, we were unable to induce AVRT. #EPeeps

[EP Mappers - Bay Area @EPbytheBay]

Bay Area's finest!

Interesting 4th re-do from OSH for incessant AFL

Peri-mitral flutter utilizing isthmus between previously isolated LAA and mitral annulus

Great maps by @mmccormickhinds
