Summary
Surgical repair of congenital aortic stenosis in children offers effective symptom relief with low risk for older children. However, infants face high operative mortality, yet surgery remains indicated due to poor prognosis.
Area of Science:
- Cardiology
- Pediatric Surgery
- Congenital Heart Disease
Background:
- Congenital aortic stenosis presents diverse forms, including valvular, subvalvular, and supravalvular obstructions.
- Surgical intracardiac repair is a treatment option for congenital aortic stenosis.
Observation:
- A study of 43 patients with congenital aortic stenosis aged 2 days to 24 years undergoing surgical repair.
- Preoperative symptoms and electrocardiogram abnormalities were common; 28% had associated cardiac defects.
Findings:
- Overall hospital mortality was 9%, with no deaths in patients over 3 months old.
- Late results showed excellent or satisfactory outcomes in 59% (valvular, older), 45% (subvalvular), and 66% (diffuse subvalvular).
- Recurrent obstruction required reoperation in six patients; late hemodynamic studies showed gradient increases in symptomatic patients.
Implications:
- Surgical intervention provides effective symptom relief and minimal morbidity in children and adolescents with congenital aortic stenosis.
- Despite high operative mortality, surgery is crucial for symptomatic infants due to their poor prognosis.
- Long-term monitoring and potential reoperations are necessary for optimal management of congenital aortic stenosis.
