5 years ago this case would probably have been abandoned. Not with the #HDGrid. A. Typical AFL -> B. Functional reentry in LAA -> C. CCW perimitral AFL -> D. Roof AFL -> E. CCW perimitral AFL with gap in anterior line -> termination. #EPeeps #ProudtobeAbbott Andres Enriquez

our first ethanol ablation for mitral annular flutter, previous failed ablation, block achieved after endocardial, CS ablation and OH, done with my friend Waël Abuzeid with tips from @MiguelVldrbno

Unedited Omnipolar Technology (OT) LAT Map vs unedited Standard Bipolar LAT map for a left lateral pathway utilizing the open window mapping technique. Who doesn’t love a one burn term? Amin Al-Ahmad, MD Abbott Cardiovascular #EPeeps #TrueEGMs #OnlyWithOT #EnsiteX

1st Epi-Endo AF case UAZ Medicine - Phoenix in 3-do: Direct evidence of human epi-endo asynchrony during persistent AF using McGriddle sandwich on dome- superimposed bipoles 3mm across wall. Nice extension of work from deGroot, Allessie, Schotten, Federov Edward Gerstenfeld Benedict Glover #QSQ

A classic VT model: Scar-based Reentry

Even something as simple as CTI block looks beautiful with #OT on #EnsiteX. Patient was a redo PVI + CTI and block was confirmed on the CTI with the #HDGrid. Andres Enriquez Jason Baley Abbott Cardiovascular #AbbottProud #EPeeps

Sometimes it’s the subtle differences with #OT. Comparison of unedited bipole (left) and OT (right) paced LAT map in a redo PVI. Tachycardia was both induced and terminated with ablation in the anterior wall gap. Andres F. Miranda-Arboleda Damian Redfearn Abbott Cardiovascular #EPeeps #AbbottProud

Recent ischemic VT case with large inferior scar... do #EPeeps try changing the voltage below conventional thresholds to visualize potential channels in the scar?

Better AF freedom at 1 yr (90% vs 65%; HR 0.26) with HPSD compared to standard power ablation, at the expense of a trend in increased ACE by brain MRI, in our international prospective randomized trial. Nice work Adam Lee Alex Voskoboinik Chris Cheung jacc.org/doi/10.1016/j.…

Had the opportunity to use the new ESI Omnipolar Near Field system this week! Exciting new technology to help differentiate far field vs near field signals based on frequency. Check out a couple representative images for our de novo PVI and redo PVI! #EPeeps #AFib

Far field signals (LAA, RSPV) auto-annotated. Reconnection sites delineated according to frequency. Thank you to Abbott Cardiovascular for the opportunity to pilot this new tech!! #FirstinCanada Excited to see how we can use this for future AF & VT cases!! # AblateVT #EPeeps

Great VT case to share #EPeeps! Ischemic VT with large inferior scar. Found an exit site - epi/mid-myocardial circuit? Termination with first ablation! Expert mapping & ablation by Eduardo Sanhueza Interesting EGMs to follow... #AblateVT Edward Gerstenfeld Joshua Moss MD Paul Zei Alexios Hadjis
