May warrant closer monitoring for aortic and LV dysfunction post-ASO in adolescents; hypothesis-generating without longitudinal data.
Does the arterial switch operation affect aortic elasticity and LV function in adolescent patients compared to healthy controls?
Patients who have undergone the arterial switch operation frequently exhibit aortic root dilatation, reduced aortic elasticity, minor aortic regurgitation, and impaired LV systolic function on MR imaging.
Grotenhuis et al. (2008) studied this question.
