SMURDEN is continuous, convenient, and patient-friendly, offering AF burden insights via smartphone Everyone already has a smartphone —> let’s use it to understand AF better. #DigitalHealth #AFib #SMURDEN Nassir Marrouche TulaneTRIAD

Did you know that #WomeninEP are only 10%(!) of arrhythmia #clinicaltrial PIs? We need to do better NOW: A summit to improve gender equity in clinical trials #leadership room 6C w/: Anne Curtis Andrea Russo Pamela Mason JaniceChyouMD Taya Glotzer And many others! #HRS2025

Women make up 54.6% of med students but only 6% of EP fellows. Women are being lost at every step ! #HRS2025 #WomeninEP #GenderEquity Nassir Marrouche TulaneTRIAD

Women are less likely to present at major conferences; not for lack of skill,but LACK OF OPPORTUNITY ! Let’s create space, not just awareness. #HRS2025 #WomeninEP #EquityInResearch TulaneTRIAD

Stratifying AF into paroxysmal vs persistent is outdated. Sinus rhythm doesn’t always mean safe. Digital health is everywhere, let’s use it. A single ECG strip, captured at the right time, can uncover what routine care might miss! Nassir Marrouche TulaneTRIAD #AFib #HRS2025 #EPeeps

PFA is fast and efficient , but stroke risk remains a major concern we don’t fully understand. Not all PFA catheters are the same. Be specific! What about the redos and how much ablation is enough ? Nassir Marrouche Vivek Y. Reddy TulaneTRIAD #HRS25 #Epeeps

Women with HFrEF and AF have a 57% higher risk of ischemic stroke, hemorrhagic stroke, and mortality compared to men! Outstanding work by Hadi Younes, MD! Nassir Marrouche TulaneTRIAD! #HRS2025

Paroxysmal AF patients with high scores stroke just like persistent AF patients. More data to move away from the binary classification! Work by Mario Mekhael from TulaneTRIAD! Nassir Marrouche #HRS25 #EPEEEPS

Great work by Joe Abi-Rached presenting the long-term incidence of AF and HFpEF! •21.6% incidence of AFib in HFpEF patients •4.3% incidence of HFpEF in AFib patients Important insights into this two-way relationship! #HRS2025 Nassir Marrouche Tulane Medicine

Amazing work by Christian Massad! Ablation density — defined by the number of ablation points per LA surface area — matters. Higher ablation density was associated with 35% lower atrial arrhythmia recurrence! #HRS2025 Nassir Marrouche TulaneTRIAD

AI is transforming AFib care from screening to management and monitoring. Using AI-driven scoring systems, we can better track patients after treatment. The future of MyAFib is bright: passive screening with a smartwatch that acts as a clinic on the wrist! Nassir Marrouche #HRS25

Remote monitoring cuts clinic visits and ICD shocks without increasing adverse events. But alert burden is high and varies by device. AI can filter out non-urgent alerts, easing workflow. Unified devices = better outcomes! Omar Kreidieh Nassir Marrouche TulaneTRIAD #HRS25 #EPEEPs

Remote monitoring lowers arrhythmia and death risk, but comes with alert burden. Strategies like filtering transmissions and proper staffing helps! Not any teamwork, but the right teamwork makes it easier and more effective! Monique Young Nassir Marrouche TulaneTRIAD #EP #HRS2025

With fibrosis guided ablation, higher ablation density (more ablation points per LA surface area) targeting fibrosis reduces recurrence risk by 30%! Work by Christian Massad! Nassir Marrouche TulaneTRIAD #HRS25 #EPeeps

CASTLE-AF —> ablate in HFrEF, but no outcome difference between PVI and PVI+. Focus on PVs, know when to stop! HFpEF remains the elephant in the room: Ablationists ablate HF docs treat with drugs CASTLE-AF II is needed to solve the dilemma! Nassir Marrouche TulaneTRIAD #HRS25

Traditional monitoring can miss AF episodes. Using one ECG strip and a 7-day window (3 days before and after), an AI model stratified patients into high vs low AF risk, capturing what ongoing monitoring might overlook! Yingshuo Liu Nassir Marrouche TulaneTRIAD #HRS25 #Epeeps

Couldn’t have a better team!!! Thank you Dr. Nassir Marrouche for the opportunity and the experience! TulaneTRIAD Heart Rhythm Society Tulane Medicine #WomeninEP #HRS25
