Aortic Supravalvular Stenosis

Common Name(s)

Aortic Supravalvular Stenosis

Aortic Supravalvular Stenosis (SVAS) is a rare genetic disorder where the beginning portion of the aorta is abnormally narrow. The aorta is the large blood vessel leaving the heart to deliver oxygen-rich blood to the body. This narrowing can cause the heart to work harder and can sometimes lead to ventricular hypertrophy, or enlargement of the lower chambers of the heart. If left untreated, it can cause shortness of breath, chest pain, or even heart failure. SVAS generally has a 50% chance of passing on to an affected individual's children, so early diagnosis and counseling is important. It is almost always a result of a harmful change in genetic material which instructs thte body how to make elastin, the protein which provides body tissue its elasticity. It is often associated with Williams-Beuren syndrome, which includes mental retardation, a peculiar face, and high blood calicum levels. It can be diagnosed with a physical exam, including listening to the heart with a stethoscope for a murmur, and an imaging test called an echocardiogram. Regular follow-up is recommended (every 6 months for infants and each year in children) in order to monitor the evolution of the stenosis, which can be corrected with surgery.

Integrin β3 inhibition is a therapeutic strategy for supravalvular aortic stenosis.
 

Author(s): Ashish Misra, Abdul Q Sheikh, Abhishek Kumar, Jiesi Luo, Jiasheng Zhang, Robert B Hinton, Leslie Smoot, Paige Kaplan, Zsolt Urban, Yibing Qyang, George Tellides, Daniel M Greif

Journal: J. Exp. Med.. 2016 Mar;213(3):451-63.

 

The aorta is the largest artery in the body, yet processes underlying aortic pathology are poorly understood. The arterial media consists of circumferential layers of elastic lamellae and smooth muscle cells (SMCs), and many arterial diseases are characterized by defective lamellae ...

Supravalvular aortic stenosis: elastin arteriopathy.
 

Author(s): Giuseppe Merla, Nicola Brunetti-Pierri, Pasquale Piccolo, Lucia Micale, Maria Nicla Loviglio

Journal: Circ Cardiovasc Genet. 2012 Dec;5(6):692-6.

 

Supravalvular aortic stenosis is a systemic elastin (ELN) arteriopathy that disproportionately affects the supravalvular aorta. ELN arteriopathy may be present in a nonsyndromic condition or in syndromic conditions such as Williams-Beuren syndrome. The anatomic findings include congenital ...
