Imaging technique for the presence of the oval foramen with the echocardiographic retrograde shunt.


Quadruple apical imaging recorded in a 30-year-old patient with a recent event. The contrast was injected into a vein that opacified the right atrium and right ventricle. A small amount of contrast is seen in the left atrium and left ventricle consistent with the foramen oval including the right-to-left shunt.
