EchoNext, a DL ECG model trained on 1.2M ECG–echo pairs, prospectively identified previously undiagnosed SHD (PPV>50%) and exceeded cardiologist performance across 11 hospitals. Public weights + 100k-labeled ECG set released. doi.org/10.1038/s41586… #AIinMedicine #CardioTwitter…
🚨 Introducing ECGFounder, a foundation model trained on over 10 million annotated ECGs, achieving expert-level performance across 150 diagnoses. Validated across diverse datasets, it generalizes well, even with single-lead inputs. @NEJM_AI Link: ai.nejm.org/doi/abs/10.105……

🧠💓 Deep learning meets congenital heart disease. This AI-ECG model predicted future LV dysfunction months before echo. You need to see this. #AIinMedicine #Cardiology #MedEd @jmayour #CardioTwitter #CardioTech #ACHD #CHD #EchoFirst #HeartFailure2025 #HeartHealth…
🚨 Can AI assess tricuspid regurgitation severity from a single echo view? EchoNet-TR, a deep learning model trained on >2M echo videos, accurately detects moderate/severe TR (AUCs up to 0.98) — all from one A4C clip. Full manuscript link: jamanetwork.com/journals/jamac……
🚨 New CardioTechX Journal Club Episode 🚨 Can an AI-enabled ECG detect diastolic dysfunction as well as echo? 📉 A novel deep learning model identifies LV filling pressures & diastolic grades with impressive accuracy (AUC up to 0.94) — even in echo-indeterminate cases.…
Nice work @jmayour pushing peds AI-ECG forward. Check out improved prediction of WPW and QTc 💪🏼
Honored to have this AI-ECG work published in JACC EP: authors.elsevier.com/a/1kn5K,siTgod… AI-ECG outperforms GE MUSE software for pediatric ECG interpretation. During readjudication, expert pediatric EPs were more likely to agree with AI-ECG classification than the original ECG reader!
Can we personalize stroke prevention for patients with #AFib ? Check out the latest @CardioTechx episode covering a novel #ML model identifying patients likely to benefit from #LAAO vs DOACs. Full manuscript from @JACCJournals: acc.org/Latest-in-Card…
🚨 CardioTechX Journal Club Episode🚨 In this episode we're highlighting a novel #MachineLearning model that identifies #AF patients that benefit most from #LAAO vs. #DOAC. Full manuscript found here: jacc.org/doi/full/10.10… #CardioTwitter #MedEd #Cardiology…

📢 New Study in @JACCJournals TAVR in high-risk patients with native AR: Dedicated devices (JenaValve/J-Valve) deliver: ✔️ Lower 30-day mortality ✔️ Higher device success ✔️ Fewer complications (residual AR, valve migration, PPI) Read more: sciencedirect.com/science/articl…
Really proud of this paper with @scott_anj and the rest of the @MayoClinic team. Looking forward to collaborating more to use these algorithms in different clinical settings to hopefully enhance pediatric care @Mayoclinicpress ahajournals.org/doi/10.1161/JA…
Check out the exciting work Dr. Samimi is doing with the Cardiology department @MethodistHosp. @TCTMD. @SaharSamimii @CardioNerds tctmd.com/news/dedicated…
@SaharSamimii crushes her oral abstract presentation at #NYvales Great new science on TAVR for pure AR. This publication will matter. @SachinGoelMD @HMethodistCV @crfheart
Incredibly proud of our stellar SHD research fellows! ⭐️ @SaharSamimii matched at @bcmhouston @BCM_InternalMed & ⭐️ @Taha_Hatab1 matched at @ClevelandClinic @CCF_IMCHIEFS! Their MATCH results are a testament to their phenomenal skills, knowledge, and dedication! 🥇 🥇
Abstract 19083: AI-Enabled ECG Detection of Atrial and Ventricular Septal Defects in Pediatric Patients | Circulation . ahajournals.org/doi/10.1161/ci… Getting very excited about the future of AI-enabled ECG screening for pediatric congenital heart defects. @scott_anj
I am so so fortunate to have completed pediatric residency at Mayo Clinic, where I was fiercely supported to complete a one year Artificial Intelligence in Healthcare Certification! What an amazing experience and opportunity. Thank you🙏 @MayoPedsRes @SiobhanPittock
This is only the beginning- Watch this space! @SaharSamimii 💫
Honored to be highlighted as a rising star in the Cardio-oncology special focus by @fsgfca . Together with Dr. @GSanadgol, we explore RV function post-cancer therapy, echocardiography limits & advanced imaging.
Accio residency !!!!
