Congenital Heart Disease

Congenital heart diseases are lesions, caused by abnormal development of the

structures of the heart. This happens in the embryonic life due to environmental or

unknown factors. The cause of congenital disease is usually unknown, but there are

multifactor reasons that are incriminated. They are said to be sporadic. This meaning that

it is not secluded to one geographic location. However this incidence is increased in those

with a positive family history associated with this kind of heart disease. Congenital heart

disease also known as CAD is part of several syndromes like Down syndrome and others.

disease also known as CAD is part of several syndromes like Down syndrome and others.

They are associated with factors like maternal alcohol ingestion and some drugs like

thalidomide, which were prescribed medications that are no longer on the market, folic

acid, and others. They are also associated with maternal diabetes, which doubles one's

chance of contracting this abnormal development or defect.

Currently there are over 15 different types of heart diseases. Most of these

defects seem to be centered upon the five main areas around the heart. The atria, veins,

ventricles, aorta and the four valves (tricuspid valve, pulmonary artery, mitral valve and

aortic valve.) There are a number of ways that the defects can occur. This can be due to

abnormal connections, leakage or narrowing in any of the four valves or

This is the appearance of bluish color to the skin, lips and

fingernails. Cyanotic heart diseases are the ones that are incompatible in life without

early intervention. This being due to the mixing of oxygenated blood with deoxygenated

blood at the level of the heart or arteries.

One common example is (VSD) ventricular septal defect. This defect is usually

located in the left or right ventricle by the appearance of a hole. Other lesions are

pulmonary stenosis, which reduces blood flow to the lungs as well as tetralogy of fallots,

a condition that involves the "tetralogy" of the following four elements (enlargement of

the right ventricle, narrowing of the pulmonic valve aligning the displaced aorta and

tricuspid atresia, which is a complete closure of the tricuspid valve. This will prevent

blood flow from the right atrium to the right ventricle.

Early diagnosis and proper medical intervention is key such as oxygen;

prostaglandin injections, antibiotics or surgical procedures which are crucial for

    Congenital heart defects in children are frightening conditions that are yet to be understood fully by cardiologists (Mayo Clinic). Ranging from a benign murmur to complete cardiac arrest, congenital heart defects are important disorders to be educated about (Fulton). Because of the potential severity of these illnesses, one should understand what is thought to cause this, forms of it, the risk involved, precautionary measures, and what the prognosis is. By having a comprehensive view on the topic, parents, teachers, health care professionals, and day care providers can have the knowledge to recognize signs and symptoms of congenital heart defects in children and treat them accordingly (National Heart, Lung, and Blood Institute). By having a well-rounded view of this condition, prevention and action can be taken (Fulton).…

    DiGeorge syndrome is an anomaly that occurs when the 22q11.2 chromosome has been deleted, causing many different symptoms in various parts of the body. Those affected by DiGeorge syndrome often display signs of heart disease and defect at birth, presence of "cleft" palate (opening in the roof of the mouth), learning disorders, autoimmune diseases (such as rheumatoid arthritis), hypocalcaemia (low presence of calcium in blood), speech disabilities, and sometimes growth disorders. This syndrome is not explicitly fatal, but cardiac disorders caused by the DiGeorge syndrome are its greatest cause of mortality. Diseases contracted from severe immunity deficiency can also lead to death. It has…
