Abstract

Abstract: OBJECTIVES: Coarctation of the aorta (CoA) can be treated either surgically or with balloon angioplasty (BA). Long-term follow-up for either treatment has been limited. Our objective was to compare long-term results of BA and surgery for treatment of native CoA in childhood. METHODS: Retrospective cohort study of patients with native CoA treated with BA or surgery between 3 months and 16 years of age. Forty-eight patients filled out questionnaires and approved review of their medical records. Twenty-four patients underwent additional testing, including 24-h ambulatory blood pressure measurement, cardiopulmonary exercise testing and cardiac magnetic resonance imaging. Results were analysed cross-sectionally and longitudinally. RESULTS: Nineteen and 29 patients received BA and surgery, respectively. Prevalence of hypertension and aneurysms was similar in both groups. Fifty percent of patients were hypertensive. Two-thirds of patients demonstrating hypertension were not receiving antihypertensive medication. Aneurysm formation occurred in 1 BA (5%) and 1 surgery (3%) patient. The BA group had a significantly higher risk of recoarctation (47% vs 24%) and reintervention (hazard ratio 2.95, 95% confidence interval 1.04–8.32). Exercise capacity and global left ventricular function were preserved in both groups and not significantly different after correction for age. Quality of life was good to excellent in the majority of the patients. CONCLUSIONS: After CoA repair in childhood, most patients perform well in daily life. However, on the long term, more than half of the patients develop hypertension and many develop re-CoA, especially in those who underwent BA. Therefore, we do not recommend BA for the treatment of native CoA in children.
