Results and mid-long-term follow-up of stent implantation for native and recurrent coarctation of the aorta.
OBJECTIVE
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.


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.


CONCLUSIONS
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.
