Coarctation of the aorta is often associated with other cardiac anomalies, especially in the infantile form. The other statements are not accurate:
- B: The ductus arteriosus is usually closed in adult-type coarctation, as it typically resolves in infancy.
- C: In infantile coarctation, the narrowing is usually located just distal to the left subclavian artery, not in the ascending aorta.
- D: Coarctation of the aorta is a significant cause of infantile heart failure, not a rare one.
- E: Rib notching, caused by erosion of the ribs due to collateral circulation, usually appears later and is not typically present by 1 year of age.
