supravalvular aortic stenosis

Dear Doc

My son was diagnosed with the above mentioned condition. What does this mean and is it serious? I know his gradiet is 11mm Hg. He is 4 and a half. I see a genetic disorder is also assosiated with this condition Williams Syndrome?

Any advice would be appreciated.

I am sure that you have read a lot about this congenital heart abnormality already. You know all about the narrowing of the area above the aortic vave which leads from the left ventricle of the heart to the largest artery in the body, the aorta. Although Williams syndrome can be associated with this condition in 30 to 50% of cases, you would already have noticed some of the obvious features of this syndrome in your son by now.his gradient of 11mmHg is relatively low at present and means that immediate surgery is not needed. the usual pressure of concern is 30mm Hg. Your son will in all probability need further investigation particularly of the circulation further on through the aorta and his lung circulation.As he is still growing he is not a candidate for any cardiac surgery at present but must attend his cardiologist for follow up.
