Hand-on wet lab session during today’s Biosense VT Principles and Biophysics course in Chicago. Jeffrey Winterfield Tim Larsen @BiosenseWebster Rush Arrhythmia Center RUSH Internal Medicine Parikshit S Sharma, MD, MPH, FACC, FHRS Hemal Nayak William H. Sauer, MD Usha Tedrow #Epeeps

ICE made all the difference today in this #3DCTI—our final CTI line was almost as tall as it was long due a pouch! Real time visualization helped improve safety and efficiency. Careful mapping creds to our fellow Aalap Narichania! University of Chicago Cardiology Fellowship UChicago Pritzker School of Medicine #Epeeps

Another good LA flutter case around the mitral annulus. Wouldn’t terminate with mitral isthmus line, but got successful block at site of scarred slow conduction (coherent) with nice fractionated EGMs. Kevin Iverson comes through again! #EPeeps @BiosenseWebster

Nice experience with the CARTOSOUND ICE catheter across the septum in the left atrium to help guide and assess WATCHMAN deployment (before and after samples shown). Thanks to Kevin Iverson & Eric DeShazo RDCS for the nice images. #LAAO #EPeeps @BiosenseWebster NM Cardiovascular

Looks nice! Kevin Iverson when do we get ours!? #EPeeps

Nice atypical atrial flutter case. History of previous PVI for #AFIB. Coherent clearly shows area of slow conduction through the Coumadin ridge (thanks Kevin Iverson, @BiosenseWebster). #EPeeps Bradley Knight

De novo perimitral flutter mapped with #octaray with amazing efficiency... 49000+ points in <10 min :) #epeeps @BiosenseWebster

Very nice sarcoid #VT case. Initially mapped in sinus rhythm with late activation pointing to scar on the basal lateral RV free wall. [Excellent maps and videos by Allie Buck, @BiosenseWebster] #EPeeps #CardioTwitter NM Cardiovascular Alex Chicos

From the Rush Center For Congenital and Structural Heart Disease. ICE for Amulet deployment. Will ICE become the dominant imaging technology for Amulet procedures. #abbottstructural #scai

🚨 Hot off the press. New #freeread in #JICE Authors Tom De Potter Andrea Sarkozy Richard Schilling investigate the feasibility and safety of the OCTARAY catheter to successfully map complex arrhythmias in a multicenter study. ⬇️⬇️⬇️ rdcu.be/cJ5Pz #EPeeps #CardioTwitter

#Epeeps 1/6 - We are happy to see our study "High-Frequency, Low-Tidal-Volume Mechanical Ventilation Safely Improves Catheter Stability and Procedural Efficiency During Radiofrequency Ablation of Atrial Fibrillation" published. Allyson Varley, PhD Heart Rhythm Clinical Research Solutions ahajournals.org/doi/10.1161/CI…

Nice case in patient with AVR, C3 maze, LAAO with incessant flutter. Initial activation map and entrainment demonstrate perimitral flutter. The C3 mitral line had just a small gap near the MV annulus. Endocardial ablation produced bidirectional mitral isthmus block.

Happy to have early access to OPTREL. Used for Ventricular and Atrial cases. Great maps. Local activation vectors are very helpful. Looking forward to making it the go to catheter, especially for VT. Seth Sheldon MD rhea pimentel @BiosenseWebster Jacob Koruth Sandeep Gautam Dr. Devi G Nair

It is with great honor on behalf of all co-investigators I present the #SURPOINT COA Study, which confirms the reproducibility, safety, and effectiveness in paroxysmal AF Link ⬇️ Montefiore Health System Montefiore Heart #JACCEP #EPeeps @BiosenseWebster JACC Journals  authors.elsevier.com/sd/article/S24…

Posterior wall scar mediated flutter mapped with #Octaray 3-3-3 by Dr Mike Porter. Full CL observed near early meets late area. #BiosenseWebster #CartoPrime #EPeeps See comments for EGMs

First ablation procedure in our newly renovated NM Cardiovascular EP lab - an incisional flutter that terminated with the first burn! Alex Chicos Graham Lohrmann Kevin Walker.

Another beautiful lateral RA flutter. Previous cardiac surgery history. Terminates with connection to the IVC. These are satisfying. [Map is handy work of Kevin Iverson] #EPeeps, #CardioTwitter @BiosenseWebster
