The value of transesophageal echocardiography in transcatheter closure of atrial septal defects in the oval fossa using the Amplatzer septal occluder

Abstract

Transesophageal echocardiography is indispensable in the evaluation of patients undergoing transcatheter closure of atrial septal defect.

Catheter closure of atrial septal defects with deficient inferior vena cava rim under transesophageal echo guidance

“…Imaging plays a critical role in all these steps. TEE and more recently ICE are now accepted as standard imaging modalities to guide catheter closure of ASD [12][13][14][15]17,18]. The advantage with the latter modality is that it avoids the need for GA.…”

Atrial septal defects type II: noninvasive evaluation of patients before implantation of an Amplatzer Septal Occluder and on follow-up by magnetic resonance imaging compared with TEE and invasive measurement

“…At present, TEE is considered the gold standard for preinterventional planning of atrial septal defect occlusion in adult patients [7][8][9]. Both the measurement of defect diameters and the evaluation of shunt volume and shunt ratio can be performed successfully by experienced investigators [8,[10][11][12][13].…”

“…Both the measurement of defect diameters and the evaluation of shunt volume and shunt ratio can be performed successfully by experienced investigators [8,[10][11][12][13]. TEE-induced complications are described in 1 in 1,000 cases [14].…”

Usefulness of cardiac computed tomography in transcatheter closure of atrial septal defect with amplatzer septal occluder

“…Even though TEE can show the entire anatomy of an ASD and facilitates monitoring of transcatheter procedures for implantation of ASO [1,11] it is associated with some inconveniences. Ko et al reported that there were no significant differences between cardiac CT and TEE in measurement of ASD size.…”

“…An accurate evaluation of the ASD is crucial for successful transcatheter closure. Transesophageal echocardiography (TEE) has been accepted as an excellent method for the complete evaluation of an ASD in transcatheter closure [1], and balloon sizing to decide the appropriate size of the device during the procedure has been generally accepted [2,3]. But these are tricky procedures because the balloon sizing technique can be inaccurate and troublesome in some circumstance [4] and the TEE, which should be performed under general anesthesia with intubation, is associated with various potential risks [5,6].…”
