The CHAMPION trial does not forward the story of LAAO. No difference for major bleeding. No difference in all bleeding when procedural bleeding is included. Numerically worse for stroke. About 60% are CHADSVASC 2/3 WHO DON'T NEED OCCLUSION if ablation successful. #OCEAN

Who is HRX for? 
As part of the production team of the #HRXInnovation Summit alongside @JonPicciniSr , I’m often asked this question—and my response is simple: HRX is built for the changemakers. It’s for those who believe that the future of arrhythmia care isn’t a distant vision—it’s taking shape now, and they want to be part of building it. Whether you're: •A cardiac electrophysiologist exploring new models of care •A researcher turning data into insight •An engineer translating innovation from concept to clinical impact •An entrepreneur or investor searching for the next leap in digital health •A nurse, tech, or allied team member driving care transformation on the ground •A patient advocate pushing for better access, outcomes, and equity HRX is your platform. For me, the invitation from HRX Producers @drsuneet & @JonPicciniSr to be part of this summit was a no-brainer. Innovation and emerging technology have always been central to my work, and HRX offers a space where bold ideas and real-world applications collide. This isn’t a traditional conference. It’s a bold space where tech meets care delivery, and science meets scalability. From digital tools to device-based therapies, from AI to actionable data—you’ll experience where cardiovascular innovation is headed and who’s leading the way. Atlanta is the backdrop. Innovation is the mission. Collaboration is the engine.

@PrashSanders @JonKalmanEP @HRSonline @peterkistler3 @drlouisesegan @thecsanz @APHRSOfficial Congrats Well deserved

Amazing and deserved recognition of an outstanding mentor, colleague and friend - congratulations @JonKalmanEP on the the Distinguished Teacher Award from @HRSonline

From EnSite X's Open Architecture w/ Contact Index to Integrated ICE, Agilis 13F, Perclose, & Amulet, I am proud of our ability to comprehensively empower physicians to treat their patients. Come by our booth and experience it for yourself at #HRS2025.

One of my favorite things about Abbott is the sheer number of life-changing solutions our teams offer. Today, there was no better demonstration of that than the joint presentation by @Drdevignair & @siddmann. #AbbottProud

What a start to HRS 2025. Stunning views 40th floor Grand Hyatt SD #epeeps

Look forward to hearing about the advancements Cara medical has made in LBBP “Recent Understanding of 3D Anatomy of the CS. Insights from Imaging” HRS satellite symp and LBCT presentation “Hierarchical Physiologic Pacing to Enhance Clinical Outcomes in CSP #HRS2025 #epeeps

Finally got an opportunity to hang out with Professor Sanders at his home turf. An impressive facility indeed. Lovely time. Thankyou @PrashSanders and @Medtronic for their hospitality #epeeps

@Drdevignair @drsuneet @Mel_Gunawardene @atulverma_md @JonPicciniSr @DrBradleyKnight @Nishaki1 @NTrayanova @jskoruth @aalahmadmd @HanyDemo Great job as always directing this summit

What an amazing two days of learning and collaboration at the 2025 Cardiac Ablation Summit!! It was an honor to serve as co-director alongside @drsuneet and to be moderating faculty panels discussing the latest innovations in AF workflows, understanding AF mechanisms, and most importantly — keeping patients at the center of care. Over the past year, we’ve seen remarkable advancements — from refining pulsed field ablation strategies to optimizing mapping and dual energy approaches. The discussions were insightful and practical, highlighting: ✅ How new workflows are improving patient outcomes ✅ Lessons learned about individualizing PFA for different patients ✅ How these insights are reshaping conversations with AF patients A huge thank you to the outstanding faculty for their expertise and insights — and to @MDT_EPAblation for hosting such an impactful event. Looking forward to continuing this momentum! #epeeps #EPInnovations #AFWorkflows #PatientCenteredCare @MDT_Cardiac @khaldountarakji

@nmarrouche @westernAFib @TulaneTriad @EPLabDigest One of my favorite meetings of the year. Thanks again for your hospitality @nmarrouche #epeeps

Another fantastic #WAFib2025! Grateful to the exceptional and enthusiastic faculty for their remarkable contributions. We look forward to seeing you all from February 26th to 28th, 2026, for #WAFib2026! @westernAFib @TulaneTriad @EPLabDigest

Thrilled to be part of #WAFib2025 in Salt Lake City—one of the most insightful & forward-thinking AFibmeetings! Honored to join world-class faculty, engage in roundtables, and be part of Thursday’s live & recorded case sessions as an operator & moderator. Big thanks to @nmarrouche & team for their hospitality & for creating a space where science meets patient care. Incredible discussions on PFA, AI, stroke prevention & EP innovations—bringing science from bench to bedside! @TulaneTriad #epeeps @StBernards

Efficiency in PFA ablation - modeling and preclinical data from Prof. Pierre Jaïs. Another great presentation at #AFSymposium2025. CAUTION: This product is under investigation and is not available for sale in any country. #AbbottProud #PFA

@atulverma_md Very interesting findings indeed

What's important about this publication is not just that contact matters, but that the overall level of hemolysis is very low with PulseSelect. De Smet et al in Europace published that hemolysis is same between Farapulse and Varipulse - about 2X more than PS. Details matter.
