Abstract:
A 9-month-old infant presented with transposition of the great arteries and intact ventricular septum. His left ventricle was thin and deconditioned. He underwent an arterial switch operation and was electively supported with a left ventricular assist device for 8 days. He subsequently made a full recovery. Elective use of left ventricular support allows an extension of the age limit for the arterial switch operation.
