WebWithin the left ventricle, the aortic root interposes between the mitral valve and the interventricular septum. The left ventricular outlet has a partially fibrous and partially muscular wall. Two of the leaflets which guard the outlet or aortic root are in fibrous continuity with the anterior or aortic leaflet of the mitral valve. WebFurthermore, the mitral leaflet lengths reported here by CMR are virtually identical to the ex vivo measurements of valves excised from HCM patients postmortem or after surgical mitral valve replacement. 6 In addition, those morphological studies demonstrated that mitral leaflet length was representative of total valve tissue area.
