In severe tricuspid regurgitation, there will be symptoms similar to right heart failure, which are mainly related to abnormalities in the circulation, and the common symptoms include abdominal distension and indigestion, lower limb edema and jugular vein varicose. 1. Abdominal distension and indigestion: mainly due to blood stasis in the digestive system, which further affects the gastrointestinal peristalsis, leading to abdominal distension and indigestion and other related symptoms. 2. Lower extremity edema: Abnormal venous return in the lower extremities can cause fluid leakage from the blood vessels and local fluid accumulation, further leading to lower extremity edema. 3. Jugular vein varicose: mainly belongs to the upper vena cava venous reflux abnormality, which further leads to jugular vein dilatation symptoms. Tricuspid regurgitation with abnormalities in the body circulation requires timely medical observation and standardized treatment under the guidance of clinicians to avoid delays in the condition.
