[Perforation of the aorta after percutaneous closure of an atrial septal defect with an Amplatz prosthesis, presenting with acute severe hemolysis].

We report a case of aortic perforation three weeks after transcatheter occlusion of an atrial septal defect (ASD) by an Amplatzer device. Revealed by acute hemolysis, this complication needed an emergency surgical operation. The fistula between the no coronary Valsalva sinus of the aorta and the left atrium was repaired. The ASD was closed by patch. This serious accident should consider a short antero-superior rim as a risk factor for aortic perforation in transcatheter closure for ASD.
