3D echocardiogram of the mitral valve (MV) from the parasternal long and apical four-chamber views

3D images of the mitral valve can be acquired from the parasternal long-axis view (A, C, E) and the apical four-chamber view (B, D, F). Multiplanar reconstruction can be used to obtain orthogonal views of the mitral valve (A-D). After careful alignment of these orthogonal planes, the third plane (solid blue line) can be used to cut through the leaflet tips to allow planimetry of the mitral valve orifice area (E and F). The resultant MVA can then be traced.
