The clinical manifestations of Tetralogy of Fallot include, firstly, cyanosis as the primary clinical symptom. The degree and onset of cyanosis are related to the severity of pulmonary stenosis, and it often appears in areas with abundant capillaries such as lips, fingers, toes, nail beds, and bulbar conjunctiva. Secondly, squatting symptoms are common among children; they often spontaneously squat for a while during walking or playing. Squatting, with the legs bent, reduces the venous return and thus decreases the load on the heart, temporarily relieving symptoms of hypoxia by reducing the right-to-left shunt. Thirdly, clubbing occurs due to long-term hypoxic conditions, which can cause capillary dilation and proliferation in the fingers and toes, and the local soft tissues and bones also grow and enlarge; fourthly, paroxysmal hypoxic attacks, which are most common in infants, can be triggered by breastfeeding, crying, emotional excitement, or anemia. These attacks suddenly occur and can lead to severe symptoms including difficulty breathing, fainting, convulsions, and even death.

Does Tetralogy of Fallot involve chromosomal abnormalities?

Tetralogy of Fallot is primarily a developmental disorder, generally unrelated to chromosomes, with no chromosomal abnormalities. The cause of the disease is still not very clear. If pregnant again and giving birth again, it generally does not recur. Therefore, couples undergoing chromosomal testing before pregnancy is a common practice. It is generally believed that the four malformations in Tetralogy of Fallot occur due to viral infections acquired by the fetus during pregnancy, the mother consuming alcohol, or the use of certain medications during pregnancy. Currently, these are considered related factors, and so far, no abnormalities have been found related to genetics or chromosomes.

Can Tetralogy of Fallot be cured?

Tetralogy of Fallot is a type of congenital heart disease linked to family genetics and is considered quite severe among congenital heart conditions. Generally, within a few months after birth, children will exhibit cyanosis of the skin. It is crucial to perform surgery on the child promptly in such cases. Currently, the level of pediatric cardiothoracic surgery in our country has developed very rapidly. For typical cases of Tetralogy of Fallot, surgical treatment can be curative. Moreover, there are no specific requirements regarding weight and age for children undergoing heart surgery nowadays. Therefore, once Tetralogy of Fallot is diagnosed in young children, it is best to perform surgery as soon as possible. These children can then grow up, develop normally, and attend school like their peers.

Can Tetralogy of Fallot be cured?

With the continuous improvement of surgical techniques, the cure rate for total corrective surgery for Tetralogy of Fallot is increasing, and the mortality rate is continuously decreasing. Mild cases may have the opportunity to undergo a one-stage corrective surgery between the ages of five and nine. However, for patients with significant clinical symptoms, palliative surgery should be performed within six months after birth. Once the general condition improves and pulmonary vasculature develops, they can proceed with the corrective surgery. Overall, the cure rate for Tetralogy of Fallot is continuously improving.

Is tetralogy of Fallot a chromosomal problem?

Tetralogy of Fallot is the most common cyanotic congenital heart disease in childhood, consisting of four defects: ventricular septal defect, obstruction of the right ventricular outflow tract, overriding aorta, and right ventricular hypertrophy. It is a type of congenital heart disease, which generally stems from abnormal cardiovascular development during fetal life, resulting in cardiovascular malformations not controlled by chromosomes. The malformation of the cardiovascular system is mainly caused by genetic factors, environmental factors, and their interactions. The exact cause of this congenital heart disease has not been fully identified yet, indicating that it is not a chromosomal disease but a result of cardiovascular developmental abnormalities during fetal life.
