Percutaneous transvenous closure of atrial septal defects (ASDs) has become feasible in
recent years, as later‐generation devices have largely overcome initial difficulties in device …

The Sideris buttoned occluding device10 is made of a polyurethane foam occluder with a
Teflon coated wire skeleton, which is positioned in the left atrium, and a polyurethane foam …

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 …

Transcatheter closure of secundum atrial septal defect (ASD) has become an alternative to
surgery. We present a patient with hemodynamic collapse secondary to cardiac perforation …

OBJECTIVES The purpose of this study was to assess safety and effectiveness of the fourth
generation buttoned device in closing atrial septal defects (ASDs) and to test the hypothesis …

Objectives: We set out to study the effect of transcatheter closure of atrial septal defect (ASD)
on right ventricular (RV) and left ventricular (LV) function assessed by myocardial …

several years using serial echocardiographic studies. Methods: All patients with isolated …

Atrial septal defect (ASD) is one of the two most common congenital heart diseases in
children and adult. After the application of catheter intervention for ASD, this became an …

Percutaneous closure has evolved to become the first-line treatment strategy for most cases
of secundum atrial septal defect (ASD) in both adults and children. Its safety and efficacy …

Objectives: This study sought to compare the safety and efficacy of the HELEX septal
occluder (HSO) with surgical repair of atrial septal defect (ASD). Background: The HSO is a …
