There is, however, limited data on the intermediate and long‐term outcome.</p> </sec> <sec id="ccd24945-sec-0003" sec-type="section"> <title>Patients and Methods</title> <p>Fifty‐six patients received 59 covered Cheatham‐Platinum stents (January 2002–December 2011) at a single center—in 54 patients as primary treatment and in 2 as a rescue. Mean age was 22.25 ± 1.2 (11–56) years and mean weight 58.6 ± 2.1 (32–99) kg. Primary end points were reduction in systolic pressure gradient and an increase in coarctation segment diameter. Changes in antihypertensive medicines and complications were recorded on follow‐up.</p> </sec> <sec id="ccd24945-sec-0004" sec-type="section"> <title>Results</title> <p>Mean coarctation segment diameter increased from 4.69 ± 0.20 to 15.1 ± 3.2 mm (<italic>P</italic> < 0.0001). The systolic gradient decreased from mean of 51.4 ± 3.4 to 4.6 ± 0.7 mm Hg (<italic>P</italic> < 0.0001). There was one death 3 days postprocedure due to cerebral anoxia. There was one dissection diagnosed 24‐hr postprocedure. At a mean follow‐up of 45.9 ± 3.9 (3–120) months, all stents were patent and in good position on computed tomography. Four (7.1%) patients underwent successful redilation. Antihypertensive medication was decreased or stopped in 37 (66%) patients.</p> </sec> <sec id="ccd24945-sec-0005" sec-type="section"> <title>Conclusions</title> <p>Covered Cheetham‐Platinum stents may be used effectively as therapy of choice in selected patients with severe coarctation of the aorta. Aortic wall complications occur even with covered stents. Covered stents provide a safe alternative to conventional stenting in the intermediate and long‐term and can be redilated safely to keep pace with somatic growth.© 2013 Wiley Periodicals, Inc.</p> </sec> </abstract>
