Tile view of an atrioventricular septal defect (AVSD). The upper left tile shows an image comparable to that of an apical 4-chamber view. In the upper right tile, the red plane perpendicular to the green plane forms the neighboring 4-chamber view, a posterior to anterior orientation is shown at the same level, at the atrioventricular junction. The lower left tile shows a cross-section of the single atrioventricular orifice, where left and right atrioventricular valve leaflets can be seen. The lower right tile shows an unusual orientation of the 3D echo, from the apex rather than the more usual view towards the atrioventricular valve, through a part of the intact interventricular septum (IVS) into the right ventricular outflow tract (RVOT).
