Congenital heart diseases (CHD) are structural or functional heart diseases that present at birth even if it is discovered later in life .

Congenital heart disease is caused by disturbance in the normal development of the heart especially during the first 6 weeks of pregnancy. Researchers aren't sure about the exact cause , but they think genetics , certain medical conditions , some medications and environmental factors, such as smoking, may play a role .

CHD in many cases may be asymptomatic and discovered accidently during the routine examination or may be presented by some clinical manifestations (e.g. Cyanosis or Murmers) and /or complications (e.g. Heart Failure Manifestations : Tachycardia , Tachypnea , Dyspnea during feeding , Diaphoresis especially during feeding

,Restlessness, irritability , Hepatomegaly , and Failure To Thrive) .

Recently diagnosis of congenital heart disease is better by using advanced technology e.g. echocardiography, magnetic resonance imaging (MRI), cardiac catheterization, angiography, and radio-active isotopes . and early diagnosis is very important as regard the manangement of the disease .

As medical care and surgical interventions have advanced over time, the treatment of many abnormalities is now available . and many infants and children with congenital heart defects are living longer and healthier lives. Many are living into adulthood, requiring ongoing, lifelong medical care for their conditions .

So information about different aspects of CHD is very important for planning health programs for long-term care and maintenance for these cases .
