Evaluation of children with aortic coarctation: A single-center experience

Abstract

Objective: Coarctation of the aorta (CoA) accounts for 3.5% of all congenital heart diseases in children. The clinical manifestations range from heart failure to asymptomatic hypertension. Treatment options include surgical repair, balloon angioplasty, and stenting. We aimed to investigate the long-term results of surgery and balloon angioplasty to identify the possible risk factors for recoarctation and predictors associated with early success in treatment modalities. Materials and Methods: The data of 138 children who underwent examinations at a tertiary center between 2015 and 2020 with the diagnosis of CoA were evaluated. The basic demographic characteristics, clinical and echocardiographic findings, results, and treatment methods of the patients were evaluated retrospectively. Results: The mean follow-up period was 75.1 months (range of 1-223). As initial treatment, 75 patients (60.5%) underwent balloon angioplasty, 44 (35.5%) underwent surgery, and 5 (4%) underwent stenting. The early success rate of balloon angioplasty and surgery was 72.5% and 79.5%, respectively. Recoarctation occurred in 47.6% of patients following the first therapy. The median reintervention-free survival time was 138 months for all patients and was significantly higher in the surgery group (P = .025). The recoarctation rate was slightly lower in the surgery group than in those who underwent balloon angioplasty, but it was not statistically significant. None of the clinical and echocardiographic findings were found to be associated with recoarctation or early success. Conclusion: The rate of recoarctation is still high in long-term follow-up after aortic coarctation treatment, and clinical and echocardiographic findings are insufficient to predict the chance of early success and the risk of recoarctation.
