Profound anatomical knowledge about the three-dimensional orientation of cardiac skeleton, including interatrial septum (IAS), interventricular septum (IVS), and each valvular annulus is important to perform safe interventions. The inferior pyramidal space is the extracardiac fibro-adipose tissue extending between the atrial and ventricular musculatures. Many important structures are concentrated around or inside the inferior pyramidal space. The aims of the presentation are: 1, to demonstrate a series of clinical structural images of the IAS, IVS, each valvular annulus, and inferior pyramidal space reconstructed in combination with the cardiac contour using multidetector computed tomography; and 2, to discuss the clinical implications of findings based on accumulated insights made by pioneers.
