Annular modeling, with intercommissural (A) and transvalvular (B) views of a real-time three-dimensional derived mitral annular model. The 36 annular data points (white spheres) have been included. The least squares plane has been superimposed on the annulus in both views. (A) The graph illustrates the manner in which the septolateral diameter (SL) is determined for each valve. (B) The graph illustrates the manner in which the intercommissural width (CW) and the mitral transverse diameter (MTD) are determined for each valve. (AC = anterior commissure; AL = anterolateral point; L = lateral annulus; PC = posterior commissure; PM = posteromedial point; S = septum.)
