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…
Just 5 years ago, HFpEF was described as the “stepchild” of HF with no approved therapies. Today, there are 5 US FDA therapies: ✅ Empagliflozin (#EMPEROR) ✅ Dapagliflozin (#DELIVER) ✅ Sotagliflozin (#SOLOISTWHF) ✅ Sacubitril/Valsartan (#PARAGONHF) ✅ Finerenone (#FINEARTSHF)
Indexed RV volumes can miss dilation, esp at extremes of body size. In JACC Advances📊, we show that relative RV size (RV/LV volume ratio) improves detection of RV dilation & predicts mortality in TR🫀. 🔗jacc.org/doi/10.1016/j.… @JiwonKimMD @zfalk13 @Tsay_What @WeillCornell
📢 New #EHJ study! Our AI screening tool for echo — EchoGo® Amyloidosis — detects cardiac amyloidosis, a life-threatening condition, with high accuracy. Developed with @MayoClinic @UChicago, tested with 18 global sites. See paper & release: ultromics.com/press-releases… #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……

Poster presentation @SCAI Our study compared Tricuspid TEER versus GDMT in patients with severe TR. Findings suggest: ✅Reduction in Mortality rate ✅Reduction in Heart Failure Hospitalisation Many thanks to Dr. @SachinGoelMD for his guidance and support. #MedTwitter #MedX
JUST OUT! @US_FDA just approved @EdwardsLifesci Sapien 3 #TAVR for asymptomatic severe AS!!! businesswire.com/news/home/2025…
🚨 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.…
Thrilled to have presented my poster on T-TEER in Orthotopic Heart Transplant Recipients at #ACC2025! @HMethodistCV @SachinGoelMD
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…
Engaged in insightful discussions at #CRT2025 on TAV-in-SAV outcomes across various degenerated heart valve types. Grateful for the opportunity to share our findings and connect with experts in the field! @CRT_meetings @crfheart
