The percutaneous closure of a large pseudoaneurysm of the ascending aorta with an atrial septal defect Amplatzer occluder: two-year follow-up.

Pseudoaneurysm of the ascending aorta is a high-risk complication following cardiac surgery. The present report describes excellent two-year follow-up results after the percutaneous closure of a very large pseudoaneurysm with an Amplatzer atrial septal defect occluder. The original cavity in the anterior mediastinum with maximal diameter 15 cm remained as only a small scar. The patient was without serious health problems both early and after two years.
