Various 3D functions utilized to assess mitral valve disease. A: 3D zoom function was utilized to obtain this image. The advantage of the zoom mode is that the entire data set can be acquired with one beat. However, the disadvantage is the low frame rate. In this example, the frame rate is 8 Hz. B: 3D full volume was used to create this image Note the frame rate of 24 Hz. C: Color 3D showing the origin of the jet, which is central, and throughout the coaptation line of the anterior and posterior leaflets.
