[MEP-03] Repair of the Cardiac Erosion Because of the Occluder Device, A Challenging Situation.

Atrial septal defect is the most common congenital heart disease in adults. Atrial septal occluder devices are popular for treating secundum atrial septal defects. However, it has risks of complications such as cardiac tissue erosion, thrombus, and effusion. A 63-year-old female patient with atrial septal erosion who underwent intervention for secundum atrial septal defect three years ago presented to the clinic. We removed the occluder device and successfully repaired the atrial septum with bovine. While intravascular techniques have been developed for the closure of atrial septal defects, surgery remains important in treatment. Furthermore, occluder devices have important risks. This case demonstrates a successful repair after cardiac tissue erosion due to the occluder device.
