Figure 17: A 3D reconstruction of a CT scan of a waxed heart specimen with CTGA and ventricular septal defect. The right - sided right atrium (RA) is aligned with the right - sided left ventricle (LV) via the mitral valve (MV) and the left - sided left atrium with the right ventricle (RV) through the tricuspid valve (TV). The pulmonary artery (PA) is aligned with the LV and there is mitral - pulmonary fibrous continuity (white arrow). The aorta (Ao) is aligned with the RV and is separated from the tricuspid valve by subaortic conus (bracket). There is a large ventricular septal defect (*) in this specimen.
