Bottom Line: Both the anatomy and morphology of the defect should be precisely evaluated before the procedure.Three-dimensional (3D) echocardiography and cardiac computed tomography are helpful for understanding the morphology of a defect, which is important because different defect morphologies could variously impact the results.During the procedure, real-time 3D echocardiography can be used to guide an accurate closure.

ABSTRACT
Transcatheter closure of atrial septal defects has become a popular procedure. The availability of a preprocedural imaging study is crucial for a safe and successful closure. Both the anatomy and morphology of the defect should be precisely evaluated before the procedure. Three-dimensional (3D) echocardiography and cardiac computed tomography are helpful for understanding the morphology of a defect, which is important because different defect morphologies could variously impact the results. During the procedure, real-time 3D echocardiography can be used to guide an accurate closure. The safety and efficiency of transcatheter closures of atrial septal defects could be improved through the use of detailed imaging studies.

Images of balloon sizing (A) and successful device implantation (B) from intracardiac echocardiography during transcatheter closure of an atrial septal defect (ASD). The balloon occlusive diameter (two-way arrow) was 14 mm (A) and a 16-mm Amplatzer septal occluder (arrow) was positioned appropriately on the ASD (B). LA, left atrium; RA, right atrium.

Figure 7: Images of balloon sizing (A) and successful device implantation (B) from intracardiac echocardiography during transcatheter closure of an atrial septal defect (ASD). The balloon occlusive diameter (two-way arrow) was 14 mm (A) and a 16-mm Amplatzer septal occluder (arrow) was positioned appropriately on the ASD (B). LA, left atrium; RA, right atrium.

Mentions: Echocardiography can be used for monitoring during ASD catheter closure. In most cases, 2D TEE or intracardiac echocardiography (ICE) has been used during the procedure even though TTE can be used in some cases. The efficacy and safety of ICE have been demonstrated32,33,34) (Fig. 7). Although it necessitates other venous access and a biplane image is not obtainable, ICE can be conveniently used by the same operator simultaneously. In particular, ICE provides a more accurate image of the posterior-inferior rim that is superior to a TEE image. An accurate size evaluation for adequate device size selection during the procedure can be performed by ICE. Rigatelli et al.35) reported their experience with ICE during ASD device closure, achieving a good outcome even without the use of balloon sizing methods.
