In moderate tricuspid regurgitation, there are no obvious clinical symptoms when the heart is in the compensatory phase, but if the heart is not compensated, it will cause clinical symptoms related to right heart insufficiency, such as gastrointestinal stagnation, which causes nausea, vomiting, etc. Tricuspid regurgitation means that blood flows from the right ventricle through the insufficiently closed tricuspid valve into the right atrium. Tricuspid regurgitation means that blood flows from the right ventricle to the right atrium via the insufficiently closed tricuspid valve. At the beginning, the heart can compensate for the normalization of the right ventricular output, but long-term tricuspid regurgitation will cause the right atrium to increase in size, and the heart will experience a period of malfunctioning, which will lead to symptoms of right cardiac insufficiency, such as fatigue, cold skin, and dyspnea. Prolonged right heart insufficiency and obstruction of venous blood flow back to the right heart can cause symptoms of venous system stasis, such as gastrointestinal stasis resulting in nausea, vomiting and other symptoms; hepatic stasis resulting in hepatosplenomegaly, pain in the liver area, and even double lower extremity edema and other symptoms. When moderate tricuspid regurgitation is detected, it is recommended to consult a regular hospital in time to further improve the relevant examinations to clarify the cause of the disease, and to treat it as soon as possible, so as to avoid delaying the disease and causing adverse consequences.
