In medical terms, TOF stands for Tetralogy of Fallot.
Understanding Tetralogy of Fallot (TOF)
Based on the provided information, Tetralogy of Fallot (TOF) is a significant congenital heart condition. This means it is a heart defect present at birth.
Key characteristics of TOF, as described in the reference:
- It is a combination of four specific heart defects.
- These defects occur together.
- TOF primarily affects infants and children.
- The combined defects change the way blood flows through the heart and lungs.
Think of it as a structural problem with the heart and its major blood vessels that disrupts the normal circulatory pathway, impacting how oxygen-poor and oxygen-rich blood are handled and distributed throughout the body.
Why is this Combination Important?
The four defects in Tetralogy of Fallot aren't just random issues; their combination creates a specific pattern of altered blood flow. This often results in less oxygenated blood circulating in the body, which can lead to symptoms like cyanosis (a bluish tint to the skin).
Understanding that TOF is not a single defect but a group of four working together is crucial for comprehending its effects and the medical approaches used to treat it.
