Overview
Prenatal ultrasounds may show a left-sided cardiac defect, renal anomalies, growth retardation, relatively short limbs, fetal edema, cystic hygroma, polyhydramnios and brachycephaly. Echocardiographies and renal ultrasounds help detect structural defects.
Echocardiography/Ultrasound
- Turner syndrome may be diagnosed or suspected prenatally because of an ultrasonography showing a left-sided cardiac defect, renal anomalies, growth retardation, relatively short limbs, fetal edema, cystic hygroma, polyhydramnios and brachycephaly.
- Echocardiography for cardiac structural abnormalities especially aortic dilation that predisposes the individual to aortic dissection and sudden cardiac death. [1]
- The aortic severity index is a useful prognostic indicator when assessing for the risk of aortic dilatation. [2]
- It is the aortic diameter corrected for body surface area and a score of more than 2.3cm/m2 indicates a high risk of aortic dissection (2-2.3cm/m2 is considered as moderate risk).
- The advice offered to moderate risk patients is restriction of activities and that offered to high risk patients is that they should completely avoid competitive sports and intensive weight training. [3]
- Echocardiography is helpful in screening the following cardiac abnormalities: [3]
- Renal Ultrasound is helpful in screening the following structural abnormalities:
2010 ACCF/AHA/AATS/ACR/ASA/SCA/SCAI/SIR/STS/SVM Guideline Recommendations: Diagnosis and Management of Patients with Thoracic Aortic Disease (DO NOT EDIT) [4]
Aortic Imaging in Genetic Syndromes (DO NOT EDIT) [4]
| Class I |
| "1. Patients with Turner syndrome should undergo imaging of the heart and aorta for evidence of bicuspid aortic valve, coarctation of the aorta, or dilatation of the ascending thoracic aorta. If initial imaging is normal and there are no risk factors for aortic dissection, repeat imaging should be performed every 5 to 10 years or if otherwise clinically indicated. If abnormalities exist, annual imaging or follow-up imaging should be done. (Level of Evidence: C)" |
| Class IIb |
| "1. In patients with Turner syndrome with additional risk factors, including bicuspid aortic valve, coarctation of the aorta, and/or hypertension, and in patients who attempt to become pregnant or who become pregnant, it may be reasonable to perform imaging of the heart and aorta to help determine the risk of aortic dissection. (Level of Evidence: C)" |
Images
Echocardiography showing aortic stenosis in Turner Syndrome
- Severely calcified and restricted unicuspid aortic valve in systole
- May have occurred secondary to a bicuspid aortic valve.
Ultrasound showing a Cystic Hygroma with hydrops fetalis Turner Syndrome
- A dilated cystic like structure is seen on the back of the neck of a 23 year old female.
- On ultrasound, a cystic hygroma is seen on the posterior aspect of the skull and cervical spine.
