Symptoms such as chest tightness, pulmonary edema and lower limb edema often occur with moderate diatriac valve regurgitation. 1. Chest tightness: moderate mitral regurgitation will cause an increase in the burden on the left heart system, resulting in left heart system failure, thus affecting the flow of blood to the lungs, resulting in insufficient blood supply to the lung tissues and chest tightness. 2. Pulmonary edema: moderate mitral regurgitation will make the pressure of the left atrium increase, cause the pressure of pulmonary veins and pulmonary capillaries to increase, and even dilate and bruise. When the patient’s blood flow increases during physical activity, the pressure of pulmonary veins and pulmonary capillaries will further increase, resulting in chest tightness, cough and cyanosis, leading to the occurrence of acute pulmonary edema. 3. Lower limb edema: moderate tricuspid regurgitation makes it difficult for blood to enter the right ventricle from the right atrium, resulting in increased pressure in the right atrium and obstruction of venous return in the upper and lower vena cava, which leads to increased venous pressure in the lower limbs, causing lower limb edema. Patients with moderate mitral valve and tricuspid valve regurgitation are advised to take rest, ensure regular work and rest, maintain a positive and optimistic mindset, avoid mental stress, and go to the hospital in time to do relevant examinations and active treatment.
