Which of the following best describes the risks associated with critical congenital heart disease (CCHD)?

The statement that delayed diagnosis increases the risk of morbidity and mortality accurately reflects the significant concerns associated with critical congenital heart disease (CCHD). In many cases, CCHD may not be immediately apparent, and the symptoms can develop or worsen over time. If CCHD is not diagnosed promptly, the infant may experience adverse effects on organ systems due to reduced oxygenation and inadequate circulation, which can lead to serious complications, including heart failure and death. Early detection is crucial because timely intervention can significantly improve outcomes and reduce the risks associated with the condition.

While respiratory issues may occur with certain conditions, they are not intrinsic to CCHD specifically, making that option less comprehensive in defining the risks of CCHD. Describing CCHD as often asymptomatic does not adequately convey the risks involved, as many cases can present with symptoms after a period of time, and this delay is critical to address. Similarly, while immediate intervention may be necessary for some cases of CCHD, not all cases require intervention at birth, particularly if the infant is stabilized; hence, this choice does not encompass the broader picture of risk management necessary for these conditions.
