CT multiplanar reconstruction showing the short-axis plane at the annular level (A), the derived four chamber (B), two chamber (C), and volume rendering of the right chambers (D). The annulus septal-lateral diameter is measured in septal to lateral direction (A, blue line) and coincides with the annulus measurement in the four-chamber view (B). The anteroposterior diameter is orthogonal at the previous one (A, orange), and coincides with the measurement in the two-chamber view (C) (3mensio Structural Heart; Pie Medical Imaging, Maastricht, The Netherlands). AP, anteroposterior; SL, septal-lateral.
