BREAKING: New #AtrialFibrillation patient resource now available. We have launched an #AFib patient website complete with AFib resources including overview, epidemiology of disease, and what to expect during catheter ablation animations. Check it out → AFanswers.com

“By doing the sense protocol, we improved the sensitivity...and the specificity compared to sinus rhythm mapping to critical regions of the VT Circuit,” said @CallMe_DrNeil on his experience using #HDGrid Mapping Catheter. Watch now and view safety info: bit.ly/3dS63Uy

Expanded #HDGrid data is now available. Check out these results, in which incidence and location of gaps following PVI was tracked across 500+ cases ⬇️. See more data from #EHRA2021: bit.ly/3xrevlj Safety Info: bit.ly/3xsA458

When indirectly compared to circular mapping catheters (CMCs) in 559 de novo #AFib ablation procedures, #HDGrid found gaps in 52.5% of patients, while CMCs found gaps in 36.7%. See more expanded data from #EHRA2021: bit.ly/3xqJM89 Safety Info: bit.ly/3eID6d3

PV isolation at RA to LA epicardial insertion via septopulmonary bundle John Ochsner Heart & Vascular Institute. After WACA, earliest egram mapped to posterior R PV carina. Isolation in <5s. Another successful #Tactiflex IDE trial case Abbott Cardiovascular. #EPeeps #EPfellows Images thx to Jessica Lunsford

#HDgrid mapped out this leak in lateral mitral line. Had to get out in the CS with #tacticathSE to terminate this one Vatsal Ladia Preston Segars Abbott Cardiovascular

Patient presented in atypical atrial flutter with two prior LA ablations a decade prior. #HDGrid Mapping Catheter was used to create reentrant LAT maps, quickly identifying the scar region and flutter activation patterns. See the case and safety info: bit.ly/3tvm9rW

Successful ablation of antegrade only peri-his AP in 34 yoM with cardiomyopathy from NCC by Daniel P. Morin John Ochsner Heart & Vascular Institute. Open-window mapping with #HDgrid revealed proximity of AP to His. Ablation at the continuous A-AP-V electrogram in NCC blocked AP in 6s. #EPeeps #EPfellows

Thanks to Dr Steve Jenkins of IC for collaborating on the 1st VOM EtOH ablation John Ochsner Heart & Vascular Institute. A VOM territory, B LAT #HDGrid map, C #Liveview termination w 1st EtOH injection, D post ablation voltage map. Cheers to teamwork! 🥂🍾 #epeeps #EPfellows Maps by Jessica Lunsford

Answer to the previous case: AT1-parahisian, AT2-CristaTerminalis. Challenging mapping due to alternating of ATs. Note how perfectly P wave correlation filter discriminates between 2 morphologies!.. #Epeeps Evgeny Lian Robert Pantlik Thomas Demming Abbott Cardiovascular #CardioTwitter

3D complete circuitry of ridge/VOM reentrant tachycardia. Yellow recorded within epi “sulcus” or “groove” and green on LSPV side of endo “ridge”. 🤝Ryan Burris, MD Nathan Shatz Andrew Beaser Gaurav A. Upadhyay Gregory Michaud @MiguelVldrbno

Double Loop Ventricular Tachycardia Activation Patterns with Single Loop Mechanisms: Asymmetric Entrainment Responses During “Pseudo-Figure-of-Eight” Reentry, by Roderick Tung and colleagues heartrhythmjournal.com/article/S1547-…

One slide to encapsulate what we have learned from epi-endo AF ablation, below: 1.) Grid epi, Abl with 30g across on endo 2.) Any far-field endo=non transmural isolation of PW 3.) Far-field bi voltage is 2-3x lower when sensing epi 4.) Epi mapping can inform where to ablate endo

Although these decisions may be out of our control, this is exactly why we need to stand together as a professIonal society Heart Rhythm Society. We need a voice in determining the future of our field, how we practice, and how we are valued. Please suggest how we can be heard CMSGov 👇

After more than a year of curveballs our guys once again step up to the plate! This is our Cardiology team staying at the hospital to care for you and your loved ones during these hard times brought by #hurricanida Thank you guys, we are very proud of you!

Multiple tachycardias in Classic Fontan pt John Ochsner Heart & Vascular Institute. Top- CW atriotomy loop with low lat delay anteriorly. Bottom- delayed area in tach #1 becomes critical isthmus for tach #2. Both blocked with atriotomy to IVC lesion set. #CardioTwitter #EPeeps #ACHD #HDGrid #EPfellows
