What is the cause of a small amount of tricuspid regurgitation in the fetus?

Nowadays, many pregnant mothers will encounter some minor problems while experiencing the torment of happiness, such as fetal movement, nausea, etc. These are relatively normal phenomena. A small amount of tricuspid valve regurgitation in the fetus is a relatively rare phenomenon. For many people who are about to become parents, it is more worrying and frightening. Let me tell you parents what a small amount of tricuspid valve regurgitation in the fetus is.

The cusp valve is the valve between the right atrium and the right ventricle, which can prevent the blood in the right ventricle from flowing back to the right atrium. Reflux seen on color ultrasound indicates that the fetal tricuspid valve is insufficient; human blood circulation: peripheral vein-right atrium-right ventricle-pulmonary artery-pulmonary vein-left atrium-left ventricle-peripheral artery. When blood is ejected from the right atrium into the pulmonary artery, the tricuspid valve will close to prevent blood from returning to the right atrium. Tricuspid valve regurgitation means that when blood is ejected from the right atrium into the pulmonary artery, it is not closed tightly, and some blood returns to the right atrium. This will cause the right atrium to expand in height, the pressure to increase, the venous blood return to be obstructed, and due to the increased load on the right ventricle, it will compensate and hypertrophy, and right heart failure is prone to occur.

The pathophysiology of tricuspid regurgitation is the result of tricuspid regurgitation, that is, the systolic blood flow returns from the right ventricle to the right atrium, causing the right atrium to be highly enlarged, the pressure to increase, and the venous blood return to be obstructed. Due to the increased load on the right ventricle, it compensates and hypertrophies, making right heart failure more likely to occur. Many normal people will experience tricuspid regurgitation. Tricuspid regurgitation can cause reflux, but it does not mean that tricuspid regurgitation must be tricuspid regurgitation. If the color ultrasound results do not detect tricuspid regurgitation, it should not be a big deal. If you really have tricuspid regurgitation, you can use medication to relieve the pain, but you must do so under the guidance of a doctor.

Mild tricuspid regurgitation is very common in normal people and does not require treatment as long as there are no symptoms. As for the fetus, it is still developing and it doesn't mean anything. Maybe it will be fine when it grows up, so mothers don't need to worry.

After reading the above introduction, have your doubts been eliminated? A small amount of tricuspid regurgitation in the fetus is a normal physiological phenomenon. There is no need to worry too much. As long as the fetus is monitored at all times and regular check-ups are done, there will be no problem. Therefore, parents should not be too anxious. Just keep a normal mind but remain vigilant.
