Honored to have this AI-ECG work published in Lancet: Digital Health.
In this study, we show AI-ECG detects current & future risk of LVEF ≤ 40% across a wide range of congenital heart lesions in kids & adults.
Thankful for our team at BCH and collaborators at CHOP & UT Austin

🫀✨ Really exciting AI-echo work in congenital heart disease.
EchoFocus-CHD is a multitask model built from ~3.6 million echo videos across ~58,000 studies, with data spanning 58 countries and 6 continents 🌍
The model showed:
🔹 Excellent internal performance for critical CHD
🔹 Important real-world testing across outside referral studies
🔹 Better international performance after retraining on broader data

🫀 Proud of this collaboration led by @jmayour: AI-enhanced infant #ECGs can accurately detect #critical #congenital #heart #disease (CCHD).
This low-cost tool could complement pulse oximetry screening, reduce late diagnoses, & improve care globally.

🧵1/Today, we published a key milestone towards AI based cardiac screening in Nature. doi.org/10.1038/s41586-025-0…
EchoNext outperformed cardiologists and found thousands of high-risk patients missed in routine care. We also made a version available to the world.

🧠💓 Deep learning meets congenital heart disease.
This AI-ECG model predicted future LV dysfunction months before echo. You need to see this.

Excited to have presented our experience with multicenter AI collaboration at @cards_lab @YaleCardiology during this #HRS2025 session chaired by @JohnTriedmanMD and @zachia5.
Outstanding talks by @Bravo__MD @jmayour and Dr Madhavan and a very engaging discussion to close the session. The future of #AI in cardiology is bright.
Thanks for highlighting the session.
Hope this is the first of many selfies!

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!
Thankful for our wonderful collaborative team

AI-ECG analysis shows promise to predict mortality in rTOF. This externally validated model complements prognostic imaging biomarkers & may serve as an inexpensive risk stratification & surveillance tool in rTOF. jacc.org/doi/10.1016/j.jacep…

Sharing our editorial @ehj_ed on the excellent work by @jmayour et al using #AI ECG to predict 5y outcomes in congenital heart disease.
We explore the potential, challenges, and future steps for AI in understudied populations and conditions.

Off the press. New Mortality Risk Score in ToF from the INDICATOR cohort.
5 independent predictors (>4 high risk):
▪️Older age at CMR
▪️Obesity (BMI ≥30 kg/m2)
▪️ToF repair type
▪️Higher RVESVi
▪️Lower BVGFI (biventricular global function index)
