Percutaneous closure of pseudoaneurysm in the left ventricle in a young child.

Pseudoaneurysm in the left ventricular outflow tract is a rare complication occurring after cardiac surgery. We report on the successful percutaneous device closure of a pseudoaneurysm in the left ventricular outflow tract, which developed in a 23-month-old girl after resection of a subaortic ridge. The pseudoaneurysm was closed using an Amplatzer Vascular Plug II.
