Task: Answer Verification
Input (English): Question: Is the presence of Down syndrome a risk factor in complete atrioventricular septal defect repair?
Answer: The presence of Down syndrome in patients with complete atrioventricular septal defect is not a risk factor for surgical repair. Because of the early development of pulmonary vascular disease, primary repair should be performed within the first 6 months of life. In the long term, reintervention on the left atrioventricular valve is more often required in children with a normal chromosomal pattern.
Output (English): no
