Development of neo-aortic root dilatation is a well-known entity among patients with congenital heart defects in whom the native pulmonary root is placed in the systemic position.1,2 Patients undergoing a Norwood procedure constitute no exception. Valve-sparing aortic root replacement, a procedure commonly utilized to treat aortic root dilatation among patients with connective tissue disorders, can be an effective form of therapy for this condition.
A 10-year-old patient status post-Fontan completion for hypoplastic left heart syndrome (HLHS) (aortic atresia, mitral atresia) demonstrated progressive neoaortic (native pulmonary) root dilatation during follow-up. A computed tomographic scan of the chest revealed an aortic root aneurysm with a diameter of 5.4 cm at the level of the sinuses of Valsalva (z-score 12, based on normative data for native aortas). Although the neo-aortic valve remained competent, near complete obliteration of the left pulmonary artery by the expanding aortic root was seen (Figure 1
