Figure legends
Figure 1. Chest CTA showed severe coarctation of the aorta with severe calcification. The constricted segment was far from the left subclavian artery. The length of the constricted segment was about 3 cm. Two constricted rings were seen, and no obvious collateral circulation was formed.
Figure 2. Preoperative aortic angiography showed that the aorta was narrowed, the degree of narrowing was about 70%, the distal end of the narrowing was expanded, and the pressure difference between the two ends of the narrowing was 80mmHg.
Figure 3. Postoperative angiography showed that the pressure difference at both ends of the aortic coarctation dropped to 0 mmHg. The covered CP stent has a good shape and a proper location.
