One data point at a time, the “hospital on the wrist” is moving closer to reality. The evidence is getting harder to ignore! Important #HEARTBEAT work by @MassadChristian, presented by @mabou_khalil at #AHA2026. Proud of our @TulaneTriad team! @PrashSanders @TinaBaykaner @gautamsand @S_NarayanMD @netta_doc @Phiso_de

Honored to present @MassadChristian ‘s exciting work from the HEARTBEAT study at #AHA2026! 🫀

Smartwatch burden (“SMURDEN”) is a scalable, readily available metric associated with increased hospitalizations, opening new doors for CV risk assessment!

Honored to welcome a force in EP @lamajebbawi to @Tulane as the newest member of our #EP team. Her expertise in experimental and clinical electrophysiology will further strengthen our program. Looking forward to advancing research, education and patient care together!

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

@peterkistler3 @DrJeremyWilliam Very interesting study! We found quite similar findings in our DECAAF-II subanalysis, where LA volume and AF burden were correlated with a similar R² of 0.12. However, we also found a significant difference in AF recurrence rates between patients with low versus high LA volumes.

Proud to be part of this work led by @PrashSanders . Pooling all 3 sham-controlled RCTs (SHAM-PVI, PFA-SHAM, PVI-SHAM-AF): AF ablation beats sham. QoL +13.5 AFEQT points, 94% probability of a clinically meaningful gain. #AFib recurrence cut in half (RR 0.49), 99% probability of benefit.@DrJasonAndrade @Mel_Gunawardene @peterkistler3 @lamajebbawi

The future is here! Excellent lecture by Dr. Youngjin Cho at #APHRS2026 on using AI to identify patients at risk for #AFib and guide targeted screening. Earlier detection opens the door to timely intervention and more personalized care. #AI #DigitalHealth @TulaneTriad @TulaneHeart
