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.
