Congrats to @drsjdan & @NagibChalfoun on their JACC publication of the MANIFEST-US registry! Corewell ranked 8th among 100+ centers in this landmark study on pulsed field AF ablation using Boston Scientific’s Farapulse catheter. Huge thanks to our EP team! doi.org/10.1016/j.jacc.2025.…

Very proud of our entire team at Corewell Health West/Frederik Meijer Heart and Vascular Institute for reaching this incredible milestone of performing 1000 Atrial fibrillation pulse field ablations with Farapulse since its short release just last year!

Another OT win! Post atypical AFL ablation, patient had continuous PACs and the #HDGrid was used to quickly map the LA. The tails of the OT vectors led to the earliest activation at the base of the LAA resulting in a one burn termination. @mdahu @ShowMeYourMaps #MidAmericaEP

More than just a PVI… Ablated WACA lines and floor/roof lines for PWI but still did not have isolation of the right carina. Remapped right veins with #HDGrid and utilized OT vectors to localize two epicardial connections in that area! @drAAlbano #OnlywithOT #MidAmericaEP [1/2]

Great Redo AF case with @NagibChalfoun that resulted in a one burn reisolation of the RSPV after less than 15 minutes of mapping with #HDGrid and using OT vectors to localize the leak #OnlywithOT #MidAmericaEP Check below 👇🏻 for termination

Redo AF case with @NagibChalfoun using #HDGrid and #EnsiteX magnetic mode. Clear difference when comparing Omnipolar and Bipolar voltage in the RSPV, giving us a clear target for a one burn reisolation. #TrueElectrograms #OnlywithOT #MidAmericaEP

Great aAFL/VOM case with @AndreGauri. 14.5 minutes and 30K points later - confirmed mitral flutter with #HDGrid. VOM extended CL 5-10MS and left us with an easy #OneBurnTerm on lateral mitral line. Under 3 minutes of RF to complete line. #MidAmericaEP

Atypical AFL with @drsjdan - - When traditional LAT mapping doesn’t tell the whole story… trust OT! Began by mapping RA with #HDGrid and #EnsiteX, and OT arrows confirmed previous CTI line still blocked.

LA mapped quickly showing roof dependent flutter. OT gave us clear electrograms and real time arrows that showed prior mitral line block, and roofline block after the roof lesion set was done. #OnlywithOT #AbbottAF #MidAmericaEP

Mapping of this redo AF showed vein isolation, which means we do PWI! #HDGrid and OT came to the rescue. Arrows ➡️➡️ and LAT mapping easily revealed leaks in PW. Loving what @AbbottCardio did with #EnsiteX. #AbbottAF #MidAmericaEP #OnlywithOT #EPeeps @NagibChalfoun
