A 7-year-old girl was presented for an evaluation of her small stature when compared to her peers. She was evaluated by an endocrinologist and diagnosed with Turner syndrome. Due to the association of Turner syndrome with cardiovascular abnormalities, an echocardiography was performed. The echocardiography showed a discrete aortic narrowing, consistent with an aortic coarctation. The peak pressure gradient estimated by echocardiography was 50 mmHg. In order to decide between endovascular treatment with angioplasty and stenting versus surgical repair, a CT angiography of the chest was performed to define the length and narrowness of the coarctation, its distance to the cervical arteries, and any stenoses in these arteries. The coarctation was surgically resected and the aorta repaired with an end-to-side connection.
