Diagnosis
Diagnosing Tetralogy of Fallot is possible even before birth. In cases where the condition is discovered during an ultrasound, a specialist may closely monitor the pregnancy and create a care plan for the immediate period after birth. However, there are instances where doctors only diagnose the condition after the baby is born, either before the family leaves the hospital or during a follow-up appointment. The diagnosis process typically involves several tests including pulse oximetry for monitoring blood oxygen levels, an electrocardiogram (ECG) to assess the heart’s electrical activity, and magnetic resonance imaging (MRI) to visualize any abnormalities.
Risk Factors
Understanding the risk factors associated with tetralogy of Fallot can help in identifying potential causes for the condition. While the exact cause remains unknown, there are several factors that can increase the likelihood of a fetus developing this condition.
Poor nutrition, alcoholism, or a viral illness during pregnancy can contribute to the risk of tetralogy of Fallot. Additionally, having a parent who has tetralogy of Fallot, a mother who is older than 40, or being diagnosed with DiGeorge or Down syndrome can also increase the chances of developing this condition.
