Objective: To investigate the natural history of secundum atrial septal defects (ASDs) over
several years using serial echocardiographic studies. Methods: All patients with isolated …

Background Several reports in the past have described the natural history of atrial septal
defects, most dealing with a decrease in size or spontaneous closure of the defect. Some …

In summary, device closure of the ASD has become standard of care for secundum ASD.
ASDs as large as 40 mm diameter can be closed using the ASO devices [28]. Midterm and …

OBJECTIVES. The goals were to assess the frequency of spontaneous closure of isolated
secundum atrial septal defect in children and to identify predictors of spontaneous atrial …

To evaluate the feasibility of transcatheter closure of secundum atrial septal defects (ASDs)
associated with deficient rims (< 5 mm) using the Amplatzer septal occluder (ASO), 23 …

There are few studies providing information on the natural course of hemodynamically
insignificant atrial septal defect (ASD). To review the outcome of patients with secundum …

BACKGROUND: Percutaneous closure of atrial septal defect (ASD) is a valid alternative to
surgical approach. Current device has significantly improved the success rate also in …

Outcomes of device closure of large and small secundum atrial septal defects (ASDs) as
related to rim anatomy with the Amplatzer atrial septal occluder were compared. Rim …

Objectives: The aim of this study was to assess long-term results of percutaneous closure of
secundum-type atrial septal defect (ASD II) using Amplatzer septal occluders (ASO) …

The aim of the study was to assess the morphology of secundum‐type atrial septal defects
(ASD) with a view to percutaneous closure using Amplatzer septal occluders (ASO). One …
