Little is known about the efficacy and safety of the 40 mm Amplatzer septal occluder (ASO).
Thirty‐three patients (22 female, 11 male) with a large secundum atrial septal defect (ASD) …

Background: Selecting the device size using a sizing balloon could oversize the ostium
secundum atrial septal defect (OSASD) with floppy margins and at times may lead to …

Immediate and medium-term experience with transcatheter closure of a secundum atrial
septal defect by the “buttoned” device in seven patients is reported. Complications occurred …

OBJECTIVE: Since 1976 a number of similar transvenous atrial septal defect occlusion
systems have been developed and applied to prevent surgical intervention with …

Objectives: The goal of this study was to report the early and late complications experienced
in atrial septal defect (ASD) transcatheter closure. Background: Atrial septal defect …

BACKGROUND: The Amplatzer septal occluder (ASO) allows the percutaneous closure of
small to very large atrial septal defects (ASDs). The CardioSEAL/STARflex (CS/SF) can be …

Aims: To evaluate the safety and efficacy of the new Cera septal occluder (CSO) for atrial
septal defect (ASD) closure as compared to the AMPLATZER Septal Occluder (ASO) …

The aim of this study was to evaluate the feasibility, safety and efficacy of transcatheter
closure of secundum atrial septal defects (ASD) in patients with complex anatomy. From …

Transcatheter closure of atrial septal defects using a double-umbrella (clamshell) device can
now be performed during an overnight hospital stay with little morbidity and no mortality. The …

Objective To report on a new technique that increases the safety of percutaneous atrial
septal defect (ASD) closure using a goose‐neck snare system. Background ASD …
