Abstract

Late cardiovascular complications after intervention for coarctation of the aorta (CoA) might be common. Such data, especially in Asian populations, are still limited. A total of 169 patients with CoA who survived balloon (n = 41) or surgical (n = 128) intervention from 1986 to 2004 were enrolled. The total follow-up was 1,776 patient-years, and the patient age at last follow-up was 14.7 ± 8.5 years. Reintervention for recoarctation, systemic hypertension, and left ventricular outflow tract obstruction (LVOTO) was subsequently noted in 57 (34%), 36 (21.3%), and 24 (14.2%) patients, respectively, without significant differences between the balloon and surgical groups. The 20-year freedom from reintervention, systemic hypertension, and LVOTO rate was 52%, 78.6%, and 80.8% in the balloon group and 59%, 51%, and 81.9% in the surgical group, respectively. The age at CoA intervention and the aortic geometry after CoA intervention of gothic type were common risk factors for reintervention for recoarctation and late systemic hypertension. In contrast, the presence of bicuspid aortic valves and gothic arch geometry after CoA intervention increased the risk of LVOTO. Plasma renin/aldosterone activities were not elevated in those with or without systemic hypertension. In conclusion, the profile of reintervention for recoarctation and late systemic hypertension after CoA interventions in our Asian cohort with CoA was similar to that observed in white patients. Asian patients might have a lower risk of LVOTO.
