Directional15UK CHD live birth prevalence is 9 per 1,000.
Single sourceEpidemiology Interpretation
While the globe's cardiac welcome committee has a strict, nearly one-in-a-hundred admission policy, the fine print reveals a surprisingly variable guest list, proving that where a baby is born significantly influences the odds of having a heart that arrived with a unique blueprint.
Outcomes and Prognosis
1Overall CHD 1-year survival is 90% post-diagnosis.
Verified2Critical CHD mortality reduced to 10% with early surgery.
Verified3Adult CHD survivors: 85% reach adulthood.

Single sourceTreatment and Management Interpretation
The art of congenital heart disease management is a symphony of staggering success, from 95% of newborns thriving after repair to 90% of women safely guided through pregnancy, yet it's soberingly underscored by the quiet 5% who require a new heart and the constant, careful balancing of medications, devices, and vigilant prevention that keeps this complex orchestra playing.
