Mild pulmonary regurgitation in children

Now with the development of society, the environment around us is getting worse and worse. The air is filled with various pollutants and dust, which is very harmful to our body. Especially for children, respiratory tract abnormalities often occur, followed by lung infections. Children often develop mild pulmonary regurgitation. This disease can cause breathing difficulties, dizziness and nausea, which is not conducive to the healthy growth of children. Next, we will introduce the specific situation of mild pulmonary valve regurgitation in children.

1. Generally speaking, there are some abnormal respiratory system phenomena, which may be caused by some lung diseases. Guidance:

Treatment plan: Take proper rest, take a lung X-ray and eat more nutrients to adjust your body condition. These will also have a certain relief effect, don't worry.

2. Pay attention to it, because mild pulmonary valve regurgitation is caused by pulmonary hypertension. If it is serious, it will cause right heart hypertrophy, and further development will lead to right heart failure and left heart failure. The common clinical cause of mild pulmonary valve regurgitation is chronic bronchitis causing pulmonary hypertension. The prognosis is good if treated early, but cardiac hypertrophy is more serious.

3. Clinical manifestations: The symptoms and signs of tricuspid regurgitation are related to the degree of valvular regurgitation. Mild regurgitation is not easily detected clinically. More serious cases may cause fatigue, poor appetite, bloating and pain in the liver area, abdominal distension, and lower limb edema.

4. Typical signs include distended jugular veins with pulsation; enlarged liver with palpable pulsation; and a holosystolic blowing murmur at the 4th intercostal space on the left side of the sternum, which increases at the end of deep inspiration (Carvallo sign). Classic signs may be absent in patients with severe tricuspid regurgitation. If the liver is sclerotic due to long-term congestion, it will no longer beat; when the right heart volume load reaches its limit, the murmur will no longer increase with inspiration, so the Carvallo sign can be negative.

The radiograph showed right atrium and right ventricle hypertrophy, bulging of the right edge of the heart, and changes caused by other valvular diseases.

The electrocardiogram shows atrial hypertrophy, tall and wide P waves; there is also right bundle branch block or right ventricular hypertrophy, and even myocardial strain. Atrial fibrillation is common.

Echocardiography and Doppler examination: Cross-sectional ultrasound can detect the size of the tricuspid valve annulus and understand the thickening of the valve, which is helpful to distinguish between relative and organic lesions. When the tricuspid valve is regurgitant, ultrasound angiography can show microbubbles moving back and forth between the tricuspid valve; Doppler can directly monitor abnormal signals from the right ventricle to the right atrium and estimate the degree of reflux.

5. Cardiovascular angiography: Right ventriculography and right anterior oblique film photography can show tricuspid regurgitation and its degree. However, since the cardiac catheter crosses the tricuspid valve, there is a potential for false positives.

The diagnosis of tricuspid regurgitation should include an understanding of the degree of regurgitation. Typical clinical signs are of certain value in diagnosing severe tricuspid regurgitation. In the past, right ventriculography was used as a means to diagnose suspicious cases and estimate the extent of regurgitation. In recent years, ultrasound and Doppler examinations have gradually replaced invasive examinations.
