Surface geometry developed in Rapidform. (A) Epicardial contour lines (imported from FindTags) and surface and (B) mitral valve leaflet and annulus contour lines (imported from Find Contours), along with the IGES surface (IGES is an internationally accepted standard protocol for transferring the information of a two-dimensional or three-dimensional model between different CAD/CAM software).

Mitral valve in the undeformed configuration. (A) Atrial view of the mitral valve with coordinate system defined. (B) The underside of the mitral valve showing the chordal insertion points. Note the edge chordae attachments along the free edge and the strut chordae attachments at the midsection of the leaflets. The anterior leaflet is green and yellow, and the posterior leaflet is blue.
