Percutaneous device closure of atrial septal defects has evolved significantly over last 20 years. Currently transcatheter closure has replaced surgical closure for the treatment of most secundum atrial septal defects. A major reason for this is lower morbidity after transcatheter closure procedures. Clinically challenging situations, such as larger atrial septal defects, atrial septal defects with deficient rims and multiple atrial septal defects, are increasingly being addressed using transcatheter approach, with improved results. This case has demonstrated that ostium secundum atrial septal defect with small lower rim can be successfully treated by the endovascular method.
