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. 👇https://t.co/l2RbCVsaRe

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.

[Han Feng @HanFengGHD]

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.

[Han Feng @HanFengGHD]

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

[Amitabh C. Pandey @AmitabhCPandey]

⭐️@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

[Han Feng @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.

[Han Feng @HanFengGHD]

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 👇

[Han Feng @HanFengGHD]

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 🙏

[Han Feng @HanFengGHD]

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

AF+HFpEF are vicious twins, feeding symptom burden, worsening outcomes, and often under-detected. Can systematic screening and targeted care finally break the cycle?

Stronger Normalization-Free Transformers – new paper.

We introduce Derf (Dynamic erf), a simple point-wise layer that lets norm-free Transformers not only work, but actually outperform their normalized counterparts.

Important work by @MekhaelMario detailing the use of #AI to further analyze data from clinical trials! #AI algorithm studying #DECAAFII found that targeting atrial myopathy/fibrosis in younger #afib population led to significant reduction in burden! @omwazni @PrashSanders @AmitabhCPandey @chris_sohns @Phiso_de @NazemAkoum @Drdevignair @S_NarayanMD @DrRoderickTung @TinaBaykaner

[Nassir Marrouche @nmarrouche]

Enjoyed having @chris_sohns as a visiting professor @TulaneMedicine @TulaneTriad! Our team learned a lot and looking forward to continuous building of discovery platforms! P.S. also enjoyed best sandwich in #US @SteinsDeli @chanholim @maxmoersdorf @BidaouiGhassan @SinusAtria

Both #OCEAN and #OPTION show strong evidence supporting the role of #afib #ablation in lowering the risk of stroke in #afib! Agree with “most important finding” statement by @kaulcsmc ! @atulverma_md @omwazni @drjohnm @DrRoderickTung @PrashSanders
