AIMS: Since the late 1980s, endovascular stents have been used in the treatment of several vascular lesions. In the last decades, stent implantation has been proposed as a reliable option for the treatment of coarctation of the aorta. In this setting, it seems to have some advantages, rendering it superior to angioplasty alone. METHODS AND RESULTS: Between December 1997 and December 2004, 71 consecutive patients (44 males and 27 females) underwent cardiac catheterization for native or recurrent coarctation of the aorta. Seventy-four stents were implanted. All discharged patients were enrolled in a follow-up programme. Every patient underwent clinical evaluation, echo-colour Doppler studies, and exercise ECG at 1 and 6 months after the stent implantation. Peak systolic gradient dropped from 39.3 +/- 15.3 to 3.6 +/- 5.5 mmHg (P = 0.0041). The diameter of the coarcted segment increased from 8.3 +/- 2.9 to 16.4 +/- 3.8 mm (P = 0.037). In our series, one death occurred in a 22-year-old girl with a recurrent coarctation of the aorta, just after stent implantation. The rate of minor complications was <2%. Re-dilatation of a previously implanted stent was performed in three patients. CONCLUSION: In our experience (the largest reported to the best of our knowledge), stenting of a coarctation/re-coarctation of the aorta represents a safe alternative treatment without a significant mid-long-term complication.
