Valve-sparing neoaortic root replacement late after the Norwood and Fontan procedures.

Neoaortic root dilatation is a significant and inevitable late complication in patients after the Norwood operation. In this report, we describe a patient who had left pulmonary artery compression and severe neoaortic regurgitation from a severely dilated neoaortic root 11 years after the Norwood operation and subsequent Fontan procedure. We performed successful valve-sparing neoaortic root replacement in this patient.
