Congenital heart disease (CHD) refers to structural defects of the heart that are present at birth. These defects can involve the walls of the heart, its valves, the blood vessels or the way that blood moves through the heart. Congenital heart defects vary from mild defects that may not need treatment, to severe defects that require immediate medical attention and surgery. https://indiahealthtour.com/congenital-heart-surgery-india-hospitals-costs/
