Recoartación de la aorta en pacientes sometidos a angioplastia percutánea con o sin implantación de stent

OBJECTIVE: Coarctation of the aorta can be treated surgically or with balloon angioplasty. The objective of our study was to describe the results after percutaneous balloon angioplasty with or without stent implantation for coarctation of the aorta and establish the incidence of recovery during follow-up. METHOD: Cohort study. 89 patients of any age where included in a follow up period of nine years. RESULTS: Of the 89 patients included in the study, 69.0% were male. The mean follow-up for all participants was 33.66 months. 32.5% of the patients had a stent implanted during the angioplasty procedure; of which 24.1% suffered recoarctation during follow-up. In the group without stent implantation, 36.6% suffered recoarctation. There was not significant difference in the survival curves of the two groups (p = 0.899). CONCLUSIONS: Stent implantation during balloon angioplasty to treat aortic coarctation did not influence in the incidence of aortic recoarctation; but factors such as preangioplasty arterial hypertension and the final angioplasty gradient > 20 mmHg is associated with aortic recoarctation.
