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.

Transthoracic echocardiography (TTE) images of an atrial septal defect (ASD) in the subcostal view (A), four chamber view (B), and parasternal short axis view (C). The ASD indicated by a white arrow (A, B) and shunt flow demonstrated by the red color (A) were proven by TTE. RA, right atrium; LA, left atrium; RV, right ventricle; LV, left ventricle; AO, aorta.

The ASD indicated by a white arrow (A, B) and shunt flow demonstrated by the red color (A) were proven by TTE. RA, right atrium; LA, left atrium; RV, right ventricle; LV, left ventricle; AO, aorta.

Mentions: Two-dimensional (2D) echocardiography is an excellent method of evaluating ASDs. TTE has been used effectively and conveniently for ASD screening (Fig. 1), and TEE has been accepted as the best method for a complete evaluation of the defect for the purpose of device closure14) (Fig. 2). Nevertheless, the evaluation of the posterior-inferior rim may be incomplete in some patients13). TEE is uncomfortable for patients, and necessitates the use of sedation or anesthesia.
