Congenital Heart Disease

Congenital heart disease is a collective term for a range of birth defects that affect the heart. These include defects within the heart walls, the heart valves, or the arteries and veins near the heart. Blood flow can slow down, go in the wrong direction or become completely blocked.

Congenital heart disease affects approximately six in every 1,000 births in England. Many children with the condition do not require treatment, but others may need to undergo a range of treatments, including medication and surgery and ongoing monitoring to track progress.

Causes

Congenital heart disease (CHD) is normally caused when the development of the heart is disrupted, usually around week 5 of pregnancy. Although a number of risk factors have been identified, in most cases the exact cause is unknown.

Risk Factors include:

  • Genetic conditions such as Down syndrome, Turner syndrome or Noonan syndrome
  • Maternal diabetes, an infection of rubella during early pregnancy or flu during the first trimester
  • Heavy drinking during pregnancy
  • Continued use of certain anti-seizure medications, acne medications or ibuprofen

Symptoms

Symptoms of congenital heart disease vary according to the type of heart defect and the severity of the condition. However, general signs include:

  • Fatigue
  • Rapid heartbeat
  • Rapid breathing
  • Cyanosis (a blue tinge to the skin, nails and lips)
  • Clubbed fingernails

In more severe cases, these symptoms develop shortly after birth. Individuals with minor defects, however, may not experience any adverse symptoms.

Diagnosis

Congenital heart disease is often detected during pregnancy during the ultrasound scans, or directly after birth, although some people do not get diagnosed until they are much older.

Congenital heart disease can be diagnosed via a physical exam and specialist heart tests.

Treatment

Treatment for congenital heart disease depends on the type of heart defect experienced, the severity of the condition and the child’s age. Mild defects usually don’t need to be treated although regular check-ups are recommended to monitor the condition.

Children with more severe heart defects may require a number of treatments including medication, catheter procedures, surgery such as a Balloon Valvuloplasty, Valve Replacement or Repair or, in some cases, a Heart transplant.
