Fetal trisomy of Fallot is usually not recommended, but some trisomy of Fallot is not too serious and can be considered to stay, case by case. Farrow’s triad is a common congenital heart disease in clinical practice, usually caused by developmental abnormalities. Fetuses with Farrow’s triad usually suffer from respiratory distress, shortness of breath, easy exertion, cyanosis of the lips, and pestle fingers, and have a low postnatal survival rate. Usually, once the diagnosis is confirmed, the pregnancy should be terminated. However, if the condition of the fetus with Trochlear Immunodeficiency Syndrome (TIS) is relatively mild after the relevant tests are performed, surgical treatment can be considered through a neonatal cardiac surgeon after birth. At present, as long as the surgery is done at an early stage, complications caused by prolonged hypoxia can be avoided, and the surgical treatment is effective in relieving the discomfort of the child, and the continuation of the pregnancy can also be considered. Whether or not the fetus can be wanted with the presence of Fallot’s trichotillomania can be determined by consulting with a medical professional.
