A 58-year-old woman with congenital recurrent aortic coarctation and severe aortic valve stenosis underwent ECG-gated 16-row multislice computed tomography (MSCT) angiography (Sensation 16, Siemens) of the thorax for treatment planning (Figure, A and B; Movie I). The MSCT scan revealed 2 consecutive stenoses: the first immediately distal to the origin of the left subclavian artery (<50% diameter reduction), and the second at the level of the isthmus (>50% diameter reduction).

The 16-row MSCT scan with volume-rendering reconstruction, performed for evaluation and treatment planning, shows the morphology of the aortic arch with the 2 stenoses (A and B). The first and more proximal one is located close (1 cm) to the origin of the left subclavian artery (A; thin arrow), whereas the second one is located at the level of the isthmus (A; thick arrow). The percutaneous interventional procedure for the positioning of the stent is shown in C and D. A follow-up MSCT scan with volume-rendering reconstructions performed after treatment shows the correct position of the stent (E and F). Ao indicates ascending aorta; LV, left ventricle; and PA, pulmonary artery.

On the basis of the risk of major surgery in this woman with severe aortic valve stenosis, we decided to stent (CP Stent; NuMed) the isthmic stenosis (Figure, C and D). During the procedure, the first stenosis was confirmed as hemodynamically less severe compared with the second one (16 mm Hg versus 50 mm . . . [Full Text of this Article]
