Can delineate site and length of coarctation, and Doppler determines the pressure gradient across it. MR or CT angiography also visualizes the site of coarctation and can identify associated collateral vessel formation.
Treatment: Coarctation of the Aorta Surgical correction (or percutaneous transcatheter stent dilation in selected pts), although hypertension may persist. Recoarctation after surgical repair may be amenable to percutaneous balloon dilatation. |
