Atrial septal device embolization within transcather structural heart disease although rare is life threatening. We present a case of a 15-year-old female who presented with a large 17mm septum secundum atrial septal defect associated with a left to right shunt and right heart dilation. The closure with atrial septal occluder (ASO) embolised into the left ventricle and couldn’t be retrieved by percutaneous methods. This otherwise healthy young female underwent emergency retrieval of the ASO via minimal access surgery with a right anterolateral mini thoracotomy. It’s important to highlight the role of minimal access surgery for retrieval of embolised percutaneous devices.
