Case 6—2003

Surgical extraction of an embolized atrial septal defect occluder device into pulmonary artery after percutaneous closure

An atrial septal defect is the most common type of congenital heart disease among adults. Surgical repair or percutaneous closure of the defect is the treatment options. Even though percutaneous closure seems to be less risky than surgical repair, it may result in fatal complications like device embolism, cardiac perforation and tamponade. Herein we report a case of the embolism of a device into the pulmonary artery after one hour of percutaneous closure in which the embolized device was surgically removed and the defect was closed with a pericardial patch.

Left-sided migration of Sideris button atrial septal occluder device

We report the case of a left-sided migrated 'Sideris button' atrial septal defect occlusion device 6 years post-implantation with a residual secundum atrial septal defect and left atrial mass. The aims of this case report are to highlight an uncommonly seen atrial septal occlusion device, the importance of a complete echocardiographic examination of the path traversed by the device to assess for local trauma to structures, and the additional anatomical information gained and diagnostic use of intraoperative 3D transoesophageal echocardiography.
