Delayed aorto-right atrial fistula following percutaneous closure of atrial septal defect.

We present the case of a 27-year-old man who underwent percutaneous atrial septal defect (ASD) repair using the Amplatzer(®) (St Jude Medical, St Paul, MN, US) septal occluder (ASO). Six weeks later, he presented with heart failure and was found to have an aorto-right atrial fistulation. He required urgent surgical device explantation and repair of the existing ASD using a pericardial patch repair technique. This is the first case to be reported from the UK describing a delayed aorto-right atrial fistula following percutaneous closure using ASO.
