Percutaneous closure of an uncommon aortic pseudoaneurysm after arterial switch repair: a case report.

ABSTRACT: Background:The development of an aortic pseudoaneurysm is a rather rare but potentially fatal complication after cardiac surgery for aortic valve and aorta disease. If a pseudoaneurysm is left untreated, it carries a substantial risk of rupture, thrombosis with subsequently systemic embolization, and compression of the surrounding structures. Case summary:We describe a case of a transcatheter repair of a more complex and uncommon pseudoaneurysm following aortic valve replacement in a patient with a history of arterial switch repair for transposition of the great arteries. The pseudoaneurysm originated from the aortic wall and connected to the left ventricular outflow tract (LVOT). The connection to LVOT was closed with a duct occluder, the neck to the aortic wall with an atrial septal defect occluder. After 1 month, the complete pseudoaneurysm was successfully thrombosed. Discussion:Percutaneous closure of a complex pseudoaneurysm after arterial switch repair is feasible and safe. However, lifelong follow-up is needed to determine the late results after transcatheter interventions.
