Risks Factors for Atrial Septal Defect Occlusion Device Migration.

Atrial septal defect (ASD) is one of the most common congenital heart defects requiring procedural intervention. In such cases, transcatheter closure of secundum ASDs has been demonstrated to be safe and effective in both children and adults, with similar success and complication rates to surgery. However, appropriate patient selection and an accurate device selection is mandatory to prevent serious complications such as ventricular arrhythmias, outflow tract obstruction of the left and right ventricle, or ischemic events secondary to the obstruction of blood flow due to device embolization.
