ObjectivesThis study sought to evaluate the outcomes of endovascular treatment with covered versus bare Cheatham-platinum stents (NuMed, Hopkinton, New York) in coarctation of aorta (CoA) patients.BackgroundCovered stenting has been newly recognized as a useful therapeutic method for patients with native CoA, but there has been no study comparing the use of covered stents with bare stents for treating CoA.MethodsIn this randomized clinical trial, 120 patients with a mean age of 23.60 ± 10.99 years (range 12 to 58 years, 79 men), with post-ductal, short-segment, severe native CoA underwent implantation of bare Cheatham-Platinum (bCP) (n = 60) or covered Cheatham-Platinum (cCP) (n = 60) stents. Patients were followed clinically at 1, 3, 6, and 12 months after the stenting and yearly thereafter. During follow-up, multislice computed tomography (64 slices) was scheduled to assess any complications.ResultsThe procedural success rate was 100% in both groups. Patients were followed for 31.1 ± 19.2 months. Although recoarctation was seen only in the bCP group during follow-up, the difference between groups did not reach statistical significance (6.7% vs. 0%; p = NS). Two cases of pseudoaneurysm (3.3%) occurred in the cCP group, but none was observed in the bCP group (p = NS). Normotensive status significantly increased during follow-up in both groups (from 15% to 73.3% in the bCP group and 16.7% to 78.3% in the cCP group, p < 0.001 for each group and not significant between groups).ConclusionsImplanting bCP and cCP stents have very high success rates with remarkable hemodynamic effects in severe native CoA patients. Patients undergoing cCP stent implantation experienced a nonsignificantly lower recoarctation rate and a higher occurrence of pseudoaneurysm formation with respect to bCP stenting during follow-up. These findings indicate that CoA stenting is a safe procedure.
