Figure 6. Echo-Doppler studies in suprasternal notch views in a patient with coarctation of the aorta; two-dimensional (A) and color Doppler (C) pictures reveal coarctation. The site of coarctation is pointed out by arrows in (A) and (C). The magnitude of flow velocity increases from the isthmic region of the aorta (B) to the descending aorta (D). Note that there is extension into the diastole of the Doppler signal as shown by the arrow in (D). Reproduced from Ref.^[10].
