Ascending aortic dilation is uncommon in children and often linked to connective tissue disorders. This study found progressive aortic dilation in four children without these conditions, necessitating Marfan syndrome guidelines for management.

Area of Science:

  • Pediatric Cardiology
  • Cardiovascular Surgery
  • Genetics

Background:

  • Dilation of the ascending aorta in children is rare and typically associated with connective tissue diseases or congenital heart defects.
  • A bicuspid aortic valve is a common predisposing factor for ascending aortic dilation.

Observation:

  • This study reports on four pediatric cases of significant ascending aortic dilation discovered incidentally.
  • None of the patients exhibited signs of connective tissue disease or predisposing cardiac anomalies.
  • Past cardiac surgeries included arterial duct ligation, aortic coarctation repair, and atrioventricular septal defect repair in three patients; one had a structurally normal heart.

Findings:

  • All four patients presented with a functionally normal, tricuspid aortic valve.

  • Progressive dilation of the ascending aorta was observed in all cases.
  • Despite the absence of typical risk factors, the progressive nature of the dilation prompted surgical consideration.

    • Implications:

    • The findings suggest that ascending aortic dilation can occur in children without established risk factors.
    • Management strategies, including surgical intervention, may need to be guided by established protocols for conditions like Marfan syndrome.
    • Further research is warranted to understand the etiology and long-term prognosis of idiopathic ascending aortic dilation in pediatric populations.
