Use of a variable loop PFA catheter with integrated 3D mapping for paroxysmal AF ablation provided a clinical benefit success rate of >85%. #PFA #AFib @tomdepotter @VivekReddyMD @atulverma_md @anteanic4 doi.org/10.1161/CIRCEP…

Significantly less acute brain emboli among left ventricular catheter ablation patients randomized to a transseptal versus a retrograde aortic approach per our @PCORI-funded #TRAVERSE trial. Thank you to our patients who helped design and implement the study, my generous EP colleagues around the US, and for investigator-initiated, peer-reviewed, government-funded original research.

Reflecting on an incredible Advanced VT course last week with @Davilandre @TimothyMaherMD1 @DrGregMichaud and #AndyLocke and the @BIDMC_VT in partnership with @jjmt_ep. Looking forward to continuing this work and to see what’s in store in the VT space!

Used the new @jjmt_ep #CARTO #FARAVIEW software for #ZeroFluoro @BSCCardiology #PFA of #AF. As shown in the video, this advancement enables #dynamic visualization of the catheter in both the flower and basket configuration automatically. @Luiscarto3 @KyleHeath89

Our data shows the great benefit of AF ablation in HF patients irrespective of their HF subtype. This has huge implications especially in those with HFpEF, where lack of atrial contraction may be crucial. @aymanhusseinmd @omwazni @Dr_Santangeli @CleClinicHVTI @Chadi_97EP

Tug tests for Watchman! ICE is invaluable for assessment of tissue contact with the device. Third example done with 2D ICE shows minimal apposition on ridge and was repositioned. Other two images are Nuvison. #EPeeps #cardiotwitter

I love being involved with such a fun project to help spread the EP love - take a listen and let me know what you think! #epeeps @ndorms08

Infarct VT w/ U-shaped WADL in sinus w/ perfect match with a “dead-end” CT wall thickness channel (@inheartmedical). No surprise the VT isthmus was there. A substrate dead end doesn’t necessarily mean bystander! VT is in 3D! @BIDMC_VT @enricoferroMD @davilandre @DrRoderickTung

VT non-inducibility at PES is not a reliable procedural endpoint for high-risk patients with structural heart disease and VT @CleClinicHVTI @SroubekJ @omwazni @aymanhusseinmd @EuropaceEiC academic.oup.com/europace/artic…

ICE (👀) guided PFA can ⬆️ Catheter contact ⬆️ FPI ⬇️ Fluoroscopy use @Dr_Santangeli @josoriomd @DanielAlyeshmer @Drdevignair @MRazminia @omwazni @nakhla_s @ALFIEEP1 @CarinaHardy4 #EPeeps

The treatment of AF going into the future will likely be PFA. Now it is the time to explore further its utility and applications in the ventricles!! Thanks to @Dr_Santangeli, @omwazni, @CleClinicHVTI for mentoring and making this possible!

Comparative Efficacy and Safety of PFA Versus RFA of Idiopathic LV Arrhythmias - PFA outperformed RFA in challenging locations like Papillary, LV summit via distal CS and direct epicardium. jacc.org/doi/10.1016/j.… Congrats to star fellow @arwayounis2 @CleClinicHVTI @omwazni

Another nice example of successful VT-Ablation in ICM with incessant VT from today using #Carto_V8 and #OctaRay under hemodynamic support with #Impella demonstrating the powerful tools Ripple Map and Complex signals. Thanks to @Phiso_de @melhamriti @BiosenseWebster, @Abiomed

Another uneventful #Varipulse case @HdzNrw. 16 impulses for PVI, 7 more for a strange low voltage area at the posterior wall. Thanks to @BiosenseWebster, @MoneebKhalaph, @MBraunEP, @chris_sohns, @GuramImnadze, @melhamriti, @VanessaSciacca_ @AGEP_DGK @YoungDgk
