The indications for treatment were native CoA in 110\/212 patients (51.9%) and re\u2010coarctation after primary surgical or interventional treatment in 102\/212 patients (48.1%). Median patient age at endovascular CoA treatment was 18.8 years [IQR 11.9; 35.8].

Freedom from re\u2010interventions (44\/158, 27.8%) did not differ between patients who received bare or covered CP stents (<jats:italic>p<\/jats:italic>\u2009=\u20090.715). Multivariable risk factor analysis identified previous CoA surgery (HR: 2.0, 95% confidence interval (CI): 1.1\u20133,9, <jats:italic>p<\/jats:italic>\u2009=\u20090.029), postdilatation (HR: 2,9, 95% CI: 1.1\u20136.3, <jats:italic>p<\/jats:italic>\u2009=\u20090.028) and age at intervention (HR: 0.96, 95% CI: 0.94\u20130.99, <jats:italic>p<\/jats:italic>\u2009=\u20090.002) as independent risk factors for re\u2010intervention.
