What is Pediatric Congenital Heart Disease?

Pediatric congenital heart disease (CHD) refers to structural heart defects present at birth, such as tetralogy of Fallot (TOF), transposition of the great arteries, and single ventricle conditions requiring Fontan palliation. These defects affect normal blood flow and often require surgical intervention in infancy or childhood. Early diagnosis and timely surgery are critical for long-term survival and quality of life.
