Abstract
BackgroundCoarctation of the Aorta (CoA) was assumed to be one of the congenital heart defects not associated with major long-term sequels. Meanwhile, it is known that there are long-term cardiovascular consequences. This study investigates the functional outcome measures in children with CoA. Methods77 children (40.3% girls, 13.1 ± 3.3 years) with CoA were examined for their functional outcome measures and compared to healthy controls (CG). Carotid Intima-Media wall thickness (cIMT) was measured by ultrasound of the common carotid artery. In addition, Health-related Physical Fitness (HrPF) was assessed by five tasks of the FITNESSGRAM® and health-related quality of life (HrQoL) was analyzed with a self-report questionnaire (KINDL-R). ResultsAfter adjustment for age and sex and in comparison to the CG, the CoA patients showed structural changes in cIMT (CoA: 0.480 ± 0.043 mm vs CG: 0.465 ± 0.033 mm; p = 0.002) and significantly lower HrPF (z-score −0.46 ± 0.7; p < 0.001; 32nd percentile). HrQoL in children with CoA was significantly better in comparison to CG (p = 0.020). ConclusionEarly onset of structural changes of the cIMT in children with CoA could be shown. These structural changes in combination with hypertension, which often is associated with CoA, should be the focus of structured follow-up during childhood. The children with CoA showed impaired HrPF in comparison, where the promotion of physical activity should be the key factor for improvement. Encouragingly they showed better HrQoL.
