Steps taken in 3D acquisition of mitral valve. A: The image sector is focused on the mitral valve. Note that a one beat full volume acquisition has been performed. B: The image is then rotated towards the viewer. Once part of the mitral annulus is in view, the green plane is extended so that the entire mitral annulus can be viewed. C, D: The image is then rotated to position the aortic valve at the 12 o clock position. Here the mitral valve is seen from the left atrial side. E: The image can also be rotated so as to visualize the mitral valve from the LV side. This view can be useful to identify mitral clefts.
