Scans of Supravalvular Aortic Stenosis and Pulmonary Stenosis in Williams syndrome Patient

This is a scan shows the two most common heart conditions related with Williams syndrome, Supravalvular Aortic stenosis and pulmonary stenoses in a 9 month old subject as a result of elastin gene deletion.

Original legend: Combo CT scan comprised of non-ECG-synchronized spiral scan with usual scan range (A, B) prospective ECG-triggered sequential scan with narrow scan range confined to conotruncal area of heart (C, D) in 9-months-old boy with Williams syndrome. Supravalvular aortic stenosis (arrows on C) and combined valvar (arrow on D) and subvalvar (arrowheads on D) pulmonary stenoses are clearly shown on prospective ECG-triggered sequential CT images (C, D).

Dose estimates are 1.6 mSv for non-ECG-synchronized spiral scan and 0.2 mSv for prospective ECG-triggered sequential scan.
