Tetralogy of Fallot (TOF) is a heart condition that includes a large hole between the ventricles, an enlarged aorta straddling the hole, a narrowing of the pulmonary artery that leads to the lung, and a thickened right ventricle. Many babies with TOF will become blue within the first three months of life while others will display symptoms such as shortness of breath, rapid breathing, fainting, abnormally round shaped nails on the fingers and toes, irritability and fatigue.
To confirm TOF, your doctor will conduct a series of tests that may include a chest X-ray, oxygen level measurement, echocardiogram, cardiac magnetic resonance imaging (MRI), and/or cardiac catheterization. The treatment for this congenital heart disease in children is surgery.
