Day 2 of #HCM9 covered the full spectrum of HCM care: imaging, surgical myectomy, myosin inhibitors, and a packed panel on translating novel drug therapies into practice. 🫀
Tagging just a few of those pictured… Drs. Dearani, @MKIttlesonMD, Khan, Quintana, @IacopoOlivotto, Saberi, @MartinMaronMD, @harry_rakowski, @MasriAhmadMD, Sherrid & @SteveOmmen.
So many more faculty made it a great day. Thank you all!

Big ideas, lots of laughs. Friday’s Imaging & AI in HCM Care panel was a #HCM9 highlight.
Drs. @MartinMaronMD, @JccmoonMoon, @DesaiMilindY, @medtmaddox, @rohan_khera, and #RaymondChan dug into how advanced imaging and AI are changing the way we diagnose, risk-stratify and follow patients with HCM, and where the field goes next. Dr. Marty Maron kept the conversation moving (and the room laughing).
Thank you to our panelists for a terrific discussion.

The final morning of #HCM9 (Sun, Oct 25) starts with an Industry Product Theater by #Lexeo Therapeutics.
Jennifer White of Lexeo will talk about how Friedreich ataxia cardiomyopathy (FA-CM) often presents with left ventricular hypertrophy that HCM specialists will recognize, but its biology, disease course and unmet needs are very different. This session explores FA-CM and Lexeo’s investigational AAV gene therapy program (LX2006), which is designed to target the root cause of the disease.
📍 Mezzanine & Livestream | 7–8 AM ET | Sun Oct 25
Open to all HCM9 registrants. Not part of the accredited program. #HCM #FriedreichAtaxia #Cardiology
Fabry disease is an under-recognized cause of HCM, and high-risk testing shows it’s more common than we thought.
Join @SanofiUS Medical Affairs at #HCM9 for “Two Organs, One Disease: Unifying the Cardio-Renal Approach to Fabry Disease” with @danmassera (NYU Langone) and Ankit Mehta (Baylor Scott & White Health).

Drs. @IacopoOlivotto and Staci Kallish will look at Fabry disease through the lens of the HCM specialist: how it overlaps with and differs from sarcomeric HCM, the diagnostic red flags, and how cardiologists and geneticists can work together to reach a definitive diagnosis. Case studies and live Q&A, moderated by Jason Babby.

Registered for #HCM9? Spend your Saturday lunch hour on a question you see in clinic every week: what does treatment look like for patients with symptomatic oHCM?
@Tikuowens walks through the evidence: trial results, safety profile, who’s a good candidate, and the practical part — how to get patients started and keep them on therapy. Bring your questions.
