Proud of @MekhaelMario for leading this DECAAF-II analysis! Our findings echo @peterkistler3’s work on AF burden, with an important distinction: LA volume also independently predicted arrhythmia recurrence after PVI. LA enlargement offers a window into atrial remodeling. In our cohort, larger atria had more fibrosis, suggesting more advanced structural disease—a substrate that may sustain #AFib despite #PVI Understanding the underlying atrial disease is central to understanding ablation outcomes. Actual current priority focus of @TulaneHeart and @TulaneTriad @Phiso_de @chris_sohns @PrashSanders @gautamsand @S_NarayanMD @TinaBaykaner @Siddmann @drjohnm

Been working my whole life for this moment; officially applied to General Surgery residency! #Match2027 From graduating from @AUBMC_Official to my current postdoctoral research fellowship @Tulane, I’m excited to take the next step toward becoming a surgeon-scientist. Incredibly grateful to everyone who has supported and guided me along the way. Looking forward to connecting with colleagues and programs throughout the interview season! #MedTwitter #GeneralSurgery AAMC ID: 14997886

AF recurs in up to 50% post-ablation, what's next is often just operator preference. Our study in Europace of 3,100+ patients: redo ablation cut death/stroke/HF by 35% vs. cardioversion (NNT=14). 🫀⚡ @nmarrouche @HanFengGHD @QMarashly 📄 doi.org/10.1093/europace/eua… #AFib #EPeeps

Excited to share that the HEARTBEAT study design is out! Let’s see where PPG assessment in a real-world setting can lead us to in Cardiovascular medicine! @nmarrouche @MassadChristian @HanFengGHD @chanholim @AlaAssaf3 @BsoulMayana @TulaneTriad @QMarashly academic.oup.com/ehjdh/advan…

A major step toward understanding what continuous, real-world wearable monitoring can tell us beyond the clinic. Proud of the team behind #HEARTBEAT — and even more excited for the clinical outcome findings coming next. Stay tuned! #DigitalHealth #CardvascularDisease #Wearables

Excited to share new work in @JACCJournals #Advances by ⭐️ @TulaneMedicine #grad & soon to be July1 #IM #residents Drs. Cecile McGarvey & Emma Lunn with great guidance from @HanFengGHD @nmarrouche. Read more about #OAC differences for #Afib in #females. 👇jacc.org/doi/10.1016/j.jacad…

Excellent work from @MassadChristian and the team! Extra-PV ablation using the VARIPULSE catheter appears to be safe and effective, with high success rates and a favorable complication profile during medium- to long-term follow-up. Exciting progress in AF ablation strategies.

Huge congratulations to @YingshuoL, our AI leader at TRIAD, for presenting the team’s work and vision for AI in cardiology at Grand Rounds at Tulane School of Medicine! Exciting to see how AI is transforming both research and clinical care in arrhythmia at Tulane.

Congrats to @mabou_khalil Great work from HEARTBEAT study, a prospective smartwatch cohort in Louisiana with high cardiovascular risk. Lower income was associated with greater comorbidity burden and higher risk of death, stroke, or hospitalizations. More to come. #ACC26

⭐️@TulaneTriad Yingshou Liu sharing his innovative work on #AI using #PPG for risk prediction of #Afib. Amazing work and more to come from #Heartbeat study! The future is exciting. @nmarrouche @TulaneMedicine @TulaneDDoM @MassadChristian @SamsungHealth @chanholim @HanFengGHD

Congrats to Dr.@BsoulMayana on her impactful work 👏 AF patients treated with amiodarone show higher mortality risk, consistent across CHA₂DS₂-VASc strata (≥2 and <2). Important signal that risk persists regardless of baseline stroke risk. #ACC26 @TulaneDDoM @TulaneTriad

Great session on AI in cardiology. Thank you @lamcardio and Dr. Seinath Adusumalli for putting it together! Incredible insights from @rohan_khera and @zachia5 on translating AI into clinical practice and trials at Yale and Mayo Clinic. Excited about the future medicine. #ACC26

Big Saturday at ACC 2026 Scientific Session 🚀 Tulane Cardiology & TRIAD across AF, ablation, health equity, prevention, CVD, PAD & HF. A full day of science. Proud of the team and excited. @JoseWileyforNYC @AIrimpen 
@AmitabhCPandey @nmarrouche #ACC26 See schedule 👇

My most favorite session at #WesternAFib. Since I first attended, @netta_doc always follows every session and gives the final wrap-up with highlights of the whole symposium. Refreshes all the remaining controversial topics and makes me think deeper every time. Really grateful 🙏

Congratulations to @montaser4k and @QMarashly on this outstanding work. 🎉 Concomitant PFA + LAAO may represent a safer, streamlined strategy for AF patients： • Lower leak
• Shorter procedure
• Comparable complications/recurrence Read more: onlinelibrary.wiley.com/doi/… #AF #PFA
