Moderate tricuspid regurgitation is not considered serious if there are no obvious symptoms, but it is more serious if symptoms such as chest tightness and dyspnea occur. This disease is usually caused by tricuspid valve insufficiency, the blood in the right ventricle can flow into the right atrium through the tricuspid valve, which leads to a series of symptoms such as chest tightness and dyspnea. If the patient has moderate tricuspid regurgitation and the symptoms are not obvious, no treatment can be given for the time being, and only regular observation and follow-up are needed. If accompanied by obvious symptoms such as chest tightness, shortness of breath, dyspnea, etc., it is necessary to seek medical treatment as soon as possible. If the disease starts acutely and progresses rapidly, the patient’s life may be jeopardized, the prognosis is poor, and surgery is needed if necessary. If suffering from tricuspid regurgitation, it is recommended to standardize the treatment under the guidance of a doctor.
