1 | INTRODUCTION
Atrial septal defect (ASD) is the most common congenital heart disease. Percutaneous closure of ASDs has become increasingly common. Device embolization is one of the major complication. The device can be retrieved percutaneously when the event occurs some hours after deploy, surgical removal is necessary when the device was deployed for long time, it is diffificult to remove the device without damage to the valvar apparatus. We herein performed a safe procedure to retrieve the migrated device by deploying from a sheath, which could minimize valve and conduction system complications.
