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/10.1111/jc… #AF #PFA

Proud to share our new publication in @JACCJournals EP Grateful for the mentorship of @nmarrouche , @chanholim , @HanFengGHD . Thanks @DrJasonAndrade for the great input in the editorial Does SMURDEN correlate with Qol and Symptoms after ablation ? jacc.org/doi/10.1016/j.…

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

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 @MassadChristian @HRSonline

Can’t wait to be in Utah in February for yet another @westernAFib #wafib2026 @PrashSanders @chris_sohns @QMarashly @drjohnm @omwazni @S_NarayanMD @TinaBaykaner @SinusAtria @HRSonline @DrRoderickTung

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

Wonderful presentation at #AHA25 by @TulaneMedicine @TulaneTriad former fellow & current #IM #resident @BidaouiGhassan on using #AI on risk of reoccurrence after ablation for #Afib. @nmarrouche @HanFengGHD @chanholim @AHAScience

Obstructive sleep apnea (OSA) raises mortality in patients with AF. Our real-world study of >18K patients shows catheter ablation reduces death by 74% and major CV events by 40%. @BidaouiGhassan #AFib #SleepApnea #Ablation Check our new paper: doi.org/10.1111/jce.70…

Obstructive sleep apnea worsens AF outcomes, but ablation may change that! Out study shows catheter ablation reduces MACE, stroke, heart failure and mortality in AF + OSA patients. Published in @JCardioEP doi.org/10.1111/jce.70…

@YingshuoL presenting a novel #AI algorithm defining high risk vs low risk #AFib from sinus ECG @ Great Wall meeting in Beijing! @TulaneTriad @TulaneMedicine

It was a tremendous honor to speak at the #StructuralHeartSummit2025 in New Orleans on AI in structural heart disease. Loved connecting with brilliant cardiologists. I firmly believe AI's role is that of a partner, and I'm excited to see this collaboration deepen in future.

I add posterior wall ablation to my PFA #AFib ablation procedure when:

Congratulations to #Yunsung presenting at #MICCAI2025! Our AI uses ablation & MRI data to learn scar formation and recommend optimal ablation parameters for less AFib recurrence, trained on the DECAAF II cohort. @nmarrouche @chanholim @MICCAI_Society @MiccaiStudents @TulaneTriad
