Modality: Anatomic specimen

Orientation: Basal short axis view

Description: This heart has been sectioned in a similar manner to the previous short axis views (A010100-141a, A010100-142a, A010100-143a, A010100-144a and 010100-145a) with the muscular interventricular septum (red dots) further dissected toward the base of the heart. This view demonstrates nicely how the right ventricular outlet wraps around the outlet of the left ventricle, and shows well the deeply wedged position of the aortic valve between the mitral valve and the septal components. The double-headed red arrows show the portion of the interventricular septum that separates the inlet component of the right ventricle from the outlet of the left ventricle. The tricuspid valve is clearly septophilic, while the mitral valve is septophobic, lacking any cordal attachments to the muscular ventricular septum. The anterior, or aortic, leaflet of the mitral valve is in fibrous continuity with the aortic valve (yellow dots).
