Figure 3: Live/real time three-dimensional transesophageal echocardiographic demonstration of encroachment of the aorta by the atrial septal defect (ASD) closure device. Multiplanar rendering mode: Upper panels. Top arrowheads point to the left atrial disc, lower arrowheads to the right atrial disc. D1 represents the measurement of the radius of the left atrial disc from the middle of the central marker band to the outer edge of the disc. D2 represents the measurement of the radius of the right atrial disc from the middle of the end screw to the outer edge of the disc. The arrow in the top right panel points to the area of contact of the left atrial disc with the aorta (AO). Lower panels. Arrowhead in the right lower panel points to the left atrial disc covering the ASD. Reproduced with permission from Bhaya M, Mutluer FO, Mahan III EF, et al. Incremental utility of live/real time three-dimensional transesophageal echocardiography in percutaneous closure of ASD. Echocardiography 2013;30:345-53
