Figure 28. Echocardiographic images in subcostal echo projections of the atrial septum illustrating an atrial septal defect (ASD) (arrow in A) before ASD occlusion (A) and placement of a buttoned device across the ASD several hours (B) and 3 months (C) following device deployment. The long arrows in (C) identify the occluder (O) on the left atrial (LA) side and the shorter arrows point out the counter-occluder (Co) on-end in the right atrium (RA). The left ventricle (LV) is marked. Reproduced from Ref.^[27].
