Assessment of aortic morphology and compliance in children and adolescents with Ullrich-Turner syndrome (UTS) using magnetic resonance imaging (MRI)

J Pediatr Endocrinol Metab. 2014 Sep;27(9-10):915-22. doi: 10.1515/jpem-2013-0332.

Abstract

Aim: The aim of this study was to evaluate the morphology and elastic properties of the aorta in children and adolescents with Ullrich-Turner syndrome (UTS) treated with growth hormone, by using magnetic resonance imaging (MRI).

Methods: Thirty-seven conscious UTS patients were examined using a 1.5-T whole-body MRI. Contrast-free three-dimensional (3D)-MR angiographies were performed, including 2D cine MRI, to calculate the aortic compliance (C) and cine of the aortic valve.

Results: Changes of aortic morphology were evident in 40% of the patients, whereas six had more than one alteration. A bicuspid aortic valve was identified in three patients that were missed by previous echocardiography. The aortic compliances in UTS patients were similar to those in healthy persons.

Conclusion: This study shows that aortic morphology and compliance can be assessed by MRI without using contrast agents and without sedation in children and adolescents with UTS.
