Congenital Heart Disease (CHD) refers to a group of heart defects that are present at birth. These defects can affect the heart's structure, function, and blood flow. Some common types of CHD include ventricular septal defects, atrial septal defects, and tetralogy of Fallot. The exact cause of these conditions is often unknown, but they can result from genetic factors or environmental influences during pregnancy. Symptoms of CHD can vary widely, ranging from mild to severe. Some infants may show signs like rapid breathing, poor feeding, or cyanosis, which is a bluish tint to the skin. Early diagnosis and treatment are crucial, and many children with CHD can lead healthy lives with proper medical care.
