“…Important information for evaluation and selection of patients for percutaneous or surgical intervention of atrial septal defect (ASD) includes defect size, shape, location, and characterization of the surrounding atrial septal tissue 1 . In imaging, the most valuable view of an ASD to provide this information and reproduce the “surgeon's view” for planning of surgical repair or percutaneous closure is an en face image.…”

“…Two‐dimensional transthoracic echocardiography (2D TTE) is often inhibited by parallel conformation between the atrial septum and the ultrasound beam in traditional views and from drop‐out when the ventricular septum is imaged in‐line and proximal to the atrial septum, creating poor ultrasound signal unless viewed from the right parasternal, modified apical, or subcostal locations. Multiplane transesophageal echocardiography (2D TEE) has been validated and widely utilized prior to either percutaneous or surgical intervention in order to facilitate accurate evaluation of ASDs 1 . By 2D TTE and multiplane 2D TEE, the diagnosis of ASD can be made and one or two dimensions can be measured; however, one cannot be certain that the maximum dimension has been delineated 2 .…”

In this report we present 12 adult patients in whom surgical or percutaneous intervention was considered for repair of atrial septal defect (ASD). Location, size, and surrounding atrial anatomy of the ASD were assessed prior to intervention in all patients with standard and live three-dimensional transthoracic echocardiography (3D TTE). In the four patients in whom intraoperative three-dimensional transesophageal echocardiographic reconstruction (3D TEE) was done, 3D TTE measurements of maximum dimension, maximum circumference, and maximum area of ASD agreed well with 3D TEE. In the seven patients who underwent transcatheter closure device insertion, live 3D TTE measurements of maximum dimension, maximum circumference, and maximum area of ASD agreed well with the sizing balloon. Additionally, since the sizing balloon measures a stretched diameter and area, a live 3D TTE stretched ASD diameter and area (derived from the actual live 3D TTE maximum circumference) were calculated and demonstrated improved agreement with the sizing balloon measurements. In all patients, > or =5 mm of atrial tissue was visualized surrounding the ASD. Further, with the addition of contrast enhancement, characterization of a small patent foramen ovale (<5 mm) was possible in one patient. Live 3D TTE accurately defined ASD location, size, and surrounding atrial anatomy in all patients studied by us. ASD characterization by live 3D TTE agreed well with 3D TEE and sizing balloon measurements.

“…The superior and inferior vena cava rims were measured in the subcostal biatrial view, which clearly displayed the superior vena cava and inferior vena cava in the same image. Anterior and posterior rims were measured in the short-axis plane, displaying the aortic root [6]. The distance from the margin of the defect to the coronary sinus, atrioventricular valves and the right upper pulmonary vein was also measured.…”

Objective: The aim of this work was to evaluate the feasibility and safety of transcatheter closure procedures for the treatment of atrial septal defects (ASDs) with insufficient rims. Methods: A total of 507 secondary ASDs were divided into two groups based on whether they had deficient rims or not (152 vs. 355 cases,respectively). Any complications, including residual shunt, heart arrhythmia, occluder translocation, etc., were followed up for 1-3 years. Results: There were no differences in gender, weight, exposure time, ECG states, pulmonary pressure, the intervention success rate, occurrence of residual shunt, the operation time and occurrence of residual shunt during follow-up between the two groups (p > 0.05). However, the occurrence of rhythm disorders was significantly different between the two groups; ASDs with deficient rims were at an elevated risk (p < 0.05). Specifically, there was a significantly higher incidence in the occurrence of arrhythmia in the deficient rims group at 24 h postoperation, but no differences in arrhythmia incidence at any of the other follow-up time points (1, 3, 6, 12 and 36 months; p > 0.05). Conclusions: Patients with deficient rims experience a high success rate of ASD intervention and low rate of complications when the procedures are performed by experienced operators.

“…All 2‐dimensional transthoracic (TTE) or transesophageal (TEE) echocardiograms performed prior to and during device implantation, as well as intracardiac echocardiograms (ICE) performed during the procedure were reviewed on Syngo Dynamic station (Siemens, Erlangen, Germany). The following structures were evaluated and measured in ASD patients: superior and inferior ASD rims (longitudinal view on TEE [∼90 degrees], subcostal short axis view on TTE), and anterior/retroaortic as well as posterior rims (short axis view on TEE [30–45 degrees], parasternal short axis view on TTE) . Rim lengths were evaluated both, as continuous and dichotomous variables with a rim length of <5 mm defined as deficient .…”
