Tricuspid valve regurgitation is normal in the human body, but it is mild and does not cause hemodynamic effects, such as an increase or decrease in blood pressure or an increase or decrease in heart rate. In patients with moderate, moderately severe, or even severe tricuspid regurgitation, it is accompanied by dyspnea, tightness in the chest, shortness of breath, decreased activity tolerance, and even pulmonary hypertension. This is because heart valve disease leads to a decrease in cardiac function, which affects cardiac systole and diastole. Therefore, once moderate or severe tricuspid regurgitation occurs, it is necessary to go to the hospital for a cardiac ultrasound to understand the condition of the heart chambers, as well as the condition of the heart function, and then evaluate the next step of the treatment plan.
