Successful Coil Embolization of a Large Ascending Aortic Pseudoaneurysm Following Explantation of the EXCOR Pediatric Ventricular Assist Device in a Patient With Acute Fulminant Myocarditis

Mechanical ventricular assistance has become a reliable tool for the support of children and infants with heart failure. The devices have shown efficacy both as a bridge to transplantation and as a bridge to recovery. The potential complications that may occur with long-term support have not been fully described. This article reports the occurrence of a large pseudoaneurysm associated with the ascending aorta following explantation of the EXCOR Pediatric ventricular assist device. A management strategy for this potentially lethal complication is described.
