Transcatheter closure of secundum atrial septal defect (ASD) and patent foramen ovale (PFO) is now widely accepted as an alternative to surgical closure. With currently available devices and techniques, approximately 80-90% of secundum ASDs and all PFOs can be closed percutaneously. While many devices are available, the use of any particular device is dictated largely by individual defect anato...

BACKGROUND Use of the Amplatzer septal occluder (ASO) for the closure of secundum atrial septal defect (ASD) has recently become the procedure of choice, while earlier the only treatment for ASD was surgical closure. This study compares the right ventricular indices of the ASO group with the surgical closure group one year after intervention in adults. METHODS From January 2008 to February 20...

Aim. To identify dysmorphic features and cardiac, skeletal, and urogenital anomalies in patients with congenital hypothyroidism. Patients and Methods. Seventeen children with congenital primary hypothyroidism were recruited. Cause for congenital hypothyroidism was established using ultrasound of thyroid and (99m)Tc radionuclide thyroid scintigraphy. Malformations were identified by clinical exa...

Case: A 36 year-old woman without significant past medical history was admitted with left-sided hemiparesis. Imaging studies confirmed a right middle cerebral artery (MCA) stroke with normal carotid arteries. Transesophageal echocardiogram (TEE) showed right heart enlargement and a large secundum atrial septal defect (ASD) (Figure 1). Using TEE guidance, an ASD occluder device was placed withou...

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). BACKGROUND Only immediate-, short-, and intermediate-term results of ASO implantation are known so far. METHODS Between September 1995 and January 2000, 151 patients underwent a successful percutaneous closure of ASD ...

BACKGROUND Although various synthetic materials and pericardium have been used for atrial septal defect (ASD) closure, investigators are continuing to search for an ideal material for this procedure. We report and evaluate a case in which autologous right atrial wall tissue was used for ASD closure. CASE In this case, we closed a secundum ASD of a 22-year-old woman who also had right atrial e...

Nowadays transcatheter closure of atrial septal defects (ASDs) is a reality in the vast majority of countries; this procedure can be done safely and effectively in skilled hands and with the appropriate devices. Accurate and precise knowledge of the anatomy of the secundum atrial septal defect and the nearby structures is essential for the effectiveness and safe performance of ASD closure. Impr...

The goal of this chapter is to review data regarding the current prevalence estimates for secundum type atrial septal defect (ASD) and to give the reader a sense as to how these prevalence data compare relative to other common cardiac defects. This chapter will also review the current understanding of cardiac and non-cardiac findings known to be associated with secundum ASD. It is recognized th...

Atrial septal defect (ASD) is one of the common congenital anomalies of the heart in humans. Its complications depend on the size of the defect and can manifest at any age. The common symptoms of ASD include dyspnea and fatigue. Most of the ASDs are associated with morbidity and mortality, Earlier the treatment, it is better to the patient. I saw a large ostium secundum defect in the heart of a...
