Tricuspid regurgitation does not usually cause pulmonary hypertension. Tricuspid valve insufficiency causes the heart’s blood flow from the right ventricle into the left atrium to back up back into a portion of the right ventricle, decreasing the amount of blood that is injected into the pulmonary arteries and resulting in lower pressure in the pulmonary arteries. Common conditions that cause pulmonary hypertension are chronic obstructive pulmonary disease, rheumatoid disorders, or congenital narrowing of the pulmonary arteries. Increased pulmonary artery pressure causes enlargement of the right ventricle, leading to relative tricuspid valve insufficiency, causing jugular venous insufficiency, lower extremity edema, ascites, gastrointestinal bruising, nausea and vomiting, and abdominal distention. Mild tricuspid valve insufficiency, generally do not need treatment, moderate and severe insufficiency, need to go to the hospital in a timely manner to improve the examination, according to the doctor’s prescription medication.
