What is Tetralogy of Fallot?

Tetralogy of Fallot or TOF is a rare heart defect that typically occurs in children. If left untreated, the condition might be fatal. The “tetra” in its name indicates that it is linked to four other issues, including ventricular septal defect, thickened right ventricle, shifted aorta, and narrow pulmonary outflow tract. Children and infants with Tetralogy of Fallot can experience cyanosis, which results in a bluish skin because of reduced circulation of oxygen. Most cases can be diagnosed during infancy, but milder symptoms would make it hard to detect until later in life. Early diagnosis is important to improve the long-term outlook. [1]
