Tetralogy of Fallot – Definition

Tetralogy of Fallot (TOF) is a combination of four heart defects. It is present at birth. These defects make it difficult for your child to get oxygen to the entire body.

The four defects are:

  • Ventricular septal defect (VSD) — A hole in the heart. It is on a wall that separates the two lower chambers.
  • Transposition — A major blood vessel (aorta) is in the wrong place.
  • Pulmonary stenosis — The valve in the heart that allows blood to pass from the heart toward the lungs is too narrow.
  • Right ventricular hypertrophy — The muscle on the right side of the heart is too thick.

(Sickle Cell Disease)

Sickle cell anemia – Definition

Sickle cell anemia is a genetic disorder. It alters the shape of the red blood cells (RBCs). This decreases their ability to carry oxygen. It can also cause acute episodes of pain. These are called a sickle cell crisis. The body will also destroy the sickle cells. The loss of RBCs results in anemia.

The change in the ability and number of RBCs can decrease the amount of oxygen for the body.

Sarcoidosis – Definition

Sarcoidosis is an inflammatory disease that may affect many different parts of the body. Small round spots, called granulomas, form in various organs. The spots hinder normal functioning of those organs.

The lungs are the most commonly affected organs. Granulomas in the lung leave less space for the air exchange that needs to take place. This can cause the lungs to stiffen. Other commonly affected organs are the skin, eyes, liver, and lymph nodes. Rarely, the brain may be affected.

(RhD incompatibility and Isoimmunization)

Rh incompatibility – Definition

Rh factor is a protein that may be found on the surface of red blood cells. If you carry this protein, your blood is Rh positive. If you don’t carry this protein, your blood is Rh negative.

Sometimes a mother with Rh negative blood is pregnant with a baby that has Rh positive blood. This can cause a problem if the baby’s blood enters the mother’s blood flow. The Rh positive blood from the baby will make the mother’s body create antibodies. This is called isoimmunization. The antibodies will attack any Rh positive blood cells. This will not cause a problem for the mother. However, the antibodies can pass to the developing baby and destroy some of the the baby’s blood cells.

Rheumatic fever – Definition

Rheumatic fever is an inflammatory condition. It involves the connective tissue in the body. The most severe complication is rheumatic heart disease. This condition may permanently damage the heart valves. Valves affects the flow of blood to and from the heart. Symptoms of valve damage often don’t appear for 10-30 years after the initial event.
