Which statement best describes a ductus-dependent CHD?

Ductus-dependent congenital heart disease is defined by a situation where the body’s circulation relies on the patent ductus arteriosus to maintain adequate blood flow to the lungs or the body. After birth, the ductus tends to constrict and close, which would abruptly reduce or cut off essential blood flow in these lesions. Because of that, these babies require stabilization soon after birth, often with a prostaglandin E1 infusion to keep the ductus open until surgery or other definitive treatment can be performed. That is exactly what the statement describes: circulation that depends on the ductus to sustain systemic or pulmonary blood flow, with early stabilization after birth to prevent collapse. The other options aren’t correct because they describe scenarios that don’t fit this dependence. One option suggests the condition does not need early postnatal stabilization, which is false since ductal closure would jeopardize circulation. Another implies prenatal management only, whereas these lesions require postnatal management to maintain ductal patency and ensure adequate flow. The statement about merely defining intervention isn’t precise enough to capture the dependence on the ductus itself.
