Cyanotic heart disease

Alternative Names:

Right-to-left cardiac shunt; Right-to-left circulatory shunt

Symptoms:

One symptom is cyanosis, usually seen as a bluish discoloration of the lips, fingers, and toes.

Some children have dyspnea (breathing problems) and adopt a squatting position after physical activity to relieve breathlessness. Others have hypoxic spells, where their bodies are suddenly starved of oxygen. These are characterized by anxiety, hyperventilation, and a sudden increase in cyanosis.

Syncope (fainting) and chest pain may occur.

Other symptoms depend on the specific type of cyanotic heart disease.

Signs and tests:

Physical examination confirms cyanosis.

The child may have clubbed fingers, an obvious thickening of the fingertips in response to the poor oxygenation.

Abnormal heart sounds, a heart murmur, and lung crackles may be heard.

Tests will vary depending on the suspected cause, but may be extensive and include a chest X-ray, a complete blood count (CBC), arterial blood gas analysis, ECG (echocardiogram), echo-Doppler, transesophageal echocardiogram (TEE), nuclear imaging tests, cardiac catheterization, and electrophysiologic study (EPS).
