Heart failure & cardiomyopathies

Automated Assessment of Right Atrial Pressure From Ultrasound Videos Using Machine Learning

JACC AdvPublished Diagnostic accuracy study

Authors' conclusion

Machine learning is capable of accurately and robustly interpreting RAP from echocardiogram videos.

Study context

Population
Echocardiogram studies with IVC ultrasound videos; subset with right heart catheterization15,828 IVC videos
Comparison
Deep learning model vs cardiologist estimates of right atrial pressure (RAP) from IVC ultrasound

  • RAP estimates vs right heart catheterization (subset): statistically indistinguishable vs catheterization gold standard
  • RAP estimates vs right heart catheterization (subset): 319 RAP measurements from right heart catheterization
