Key result
The proposed echo-segmentation deep learning architecture predicted left ventricular ejection fraction from echocardiography videos with a mean absolute error of 4.27 and an R2 score of 0.73.
Why the study?
Assessing left ventricular ejection fraction from echocardiography videos remains a manual and time-consuming task in clinical workflows.
Does a two-stage deep learning architecture using pre-trained masked autoencoders improve the automated prediction of LVEF and left ventricular segmentation from echocardiography videos?

Marie-Luise Grausenburger (2026) studied Cardiovascular diseases (LVEF assessment) (n=10,030). echo-segmentation (two-stage deep learning architecture with VideoMAE) vs. State-of-the-art methods was evaluated on Mean Absolute Error for Left Ventricular Ejection Fraction (LVEF) prediction. The proposed echo-segmentation deep learning architecture predicted left ventricular ejection fraction from echocardiography videos with a mean absolute error of 4.27 and an R2 score of 0.73.
