Abstract:
Percutaneous closure of multiple atrial septal defects can be more challenging. It is often discussed whether a single or dual device closure is appropriate for two or more large atrial septal defects with insufficient distance between defects. In this case, we used radiofrequency energy-assisted wire atrial septostomy to break intervening tissue between two adjacent oval fossa defects, thereby combining them into a single hole and facilitating device closure using a single device. This technique could be considered in patients with multiple adjacent secundum defects separated by intervening tissue.
