Emergency criteria and lifesaving intervention windows for high-risk critical congenital heart disease: a perspectives.

Critical congenital heart disease (CCHD) is a major cause of neonatal cardiovascular instability and early mortality. Delays in recognition and definitive intervention frequently result in preventable end-organ injury or death. This perspectives proposes a physiology-based framework defining emergency clinical criteria and time-sensitive intervention windows for critical CHD to support rapid and effective decision-making.
