Use of an atrial septal defect occluder for the closure of an ascending aorta pseudoaneurysm after coronary artery bypass grafting.

An aortic pseudoaneurysm is a rare, but serious condition which can result in life-threatening complications. It is usually caused by previous cardiac surgery, trauma, or infection. Due to the high likelihood of rupture with primary surgical intervention, endovascular closure may be performed as the standard of care in eligible cases. In this article, we present a case of a huge aortic pseudoaneurysm with a wide neck which could safely be closed using an atrial septal occluder.
