Excellent read: “Epic was never built to ingest or learn from this scale of data. It was built to satisfy billing requirements, regulatory checklists, and documentation workflows. That is the beginning and end of its architecture. It is not a learning system, much less an AI
I recently took @tszzl and @RichardHanania (true story lolz-and both advisors to my new venture in full disclosure) to one of the countries largest academic medical centers. @tszzl has since wrote a viral X thread thats worth reading again https://t.co/8kKnSDObh2 It speaks for

Presented at #AHA25: In patients with atrial fibrillation and a drug-eluting stent placed at least 1 year earlier, monotherapy with a non–vitamin K antagonist oral anticoagulant was noninferior to combination therapy with clopidogrel for net adverse clinical events. Full ADAPT

Great to see momentum in this space. Important to consider proper shielding mechanisms. Keep up the great work @PWesslyMD !

#echofirst detection of LAA thrombus can be very challenging…even in TEE 👉 I usually use multiplane imaging, looking at LAA in different planes 👀 A 🇩🇪 expert proposal⬇️ https://t.co/JBDASNsa5a 👉 intraop TEE case example
Question for #echofirst folks. I have not seen this before. TEE performed prior to cardioversion. LAA before and after UEA. Why are post UEA images without a filling defect? If someone can educate me on why this is the case here? @WvuCvFellows @CASivaram1 @argulian @iamritu
