Today @TheLancet published our AMIE study with @BIDMC_Medicine, the first prospective study of patient-facing conversational diagnostics in a real clinic.
AMIE is a research system people can chat with before doctors appointments. Testing AMIE outside the lab with real urgent care patients showed how technology can help gather medical histories safely. Clinicians reported that the summaries helped them prepare for visits in 75% of cases and influenced their approach to care in more than half. AMIE’s differential diagnoses also matched the doctors’ final diagnoses 90% of the time giving clinicians more time to focus on patient care.
It’s Google’s first-ever paper in The Lancet’s main journal!

Today we launched Kolibri. On German National Day.
A new LLM aleph-alpha.com/en/kolibri/ from Aleph Alpha available under Apache 2.0.
Its been an intense few months across pre and post training to make this real. Look forward to getting adoption and feedback!

I built an interactive echocardiography tutorial with Claude Code.
Chapter 07: a 3D heart, the standard imaging views, the probe position, and simulated ultrasound video.

TOF pt with anomalous RCA from mid LAD with typical pre-pulmonic course. It’s a “benign” finding , but surgeons should be made aware. As opening the superior sternum can potentially lead to RCA injury. #ACHD ❤️🩹
Excited for our #CABA-MiTRA-AFNET12-DZHK34 Kick-off Meeting at the #DGK #2026Herztage in Hamburg!
📅 Date & time: 25 September 2026, 09:45–11:45

Dr. @Garedg23, et al observed high rates of cardiometabolic risk factors in Mexican #ACHD pts & risk profiles varied by #CHD lesion complexity. Results highlighted the need for ongoing metabolic health surveillance in the ACHD population. bit.ly/3RyFdF2 #JACCAdvances
Just tried out the new Vsan Air SL. Impressed by the image quality for its size. Attached is a video comparing its #echofirst images with a state-of-the-art machine. Worth a look #ESCCongress #POCUS @ASE360

Mit minimal-invasiven Verfahren können undichte #Herzklappen ohne Operation am offenen Herzen wieder "abgedichtet" werden. Spezialist*innen im UKM-#Herzzentrum implantieren die #Mitralklappenprothese einfach per Herzkatheter. | #EMAH

Apical sparing on strain echocardiography in patients with severe aortic stenosis is not specific of cardiac amyloidosis, and the pattern usually disappears after aortic valve replacement

I found another med mystery
(Another) Non-random obs study finds left atrial appendage closure w a device associates w LOWER mortality
ahajournals.org/doi/10.1161/…
The mystery: device= no reduction of stroke, more bleeding, but it associates w lower death rate w/in 6 months

I asked #ChatGPT (AI based chat tool) to write a poem about the mitral valve. Impressive!
