Three-dimensional echocardiography (3D echo) parametric models of the mitral valve

Color-encoded parametric models of the mitral valve obtained from 3D echocardiographic images in four different patients demonstrating (top, from left to right): normal anatomy, P3 flail scallop, P2 and P3 prolapse, and Barlow's disease. Shown below is the improvement in the diagnostic accuracy gained by the addition of the color-encoded models by readers with different levels of experience. Note that the models mostly improved the interpretation by novice readers, bringing them to the level of intermediate experience.
