Figure 10: This is a live 3D transesophageal echocardiogram immediately following device closure of a fenestrated atrial septum with a cribriform Amplatzer septal occluder. The viewer is ‘virtually’ placed inside the left atrium, looking rightwards and posteriorly. The entire left atrial disk of the device is seen, with its central umbilication and the meshwork of metal that constitutes its frame. Part of the inferior portion of the right atrial disk (RA disk) and the tricuspid valve apparatus (TV) are also seen. I, inferior; L, left
