Mild tricuspid valve insufficiency can be left untreated for the time being if there are no clinical symptoms or organic lesions; if there is underlying disease such as right heart failure, the underlying disease needs to be treated. Mild regurgitation alone without organic lesions and symptoms usually requires no treatment and clinical observation is sufficient. Tricuspid regurgitation in combination with primary disease such as pulmonary hypertension or right heart dysfunction requires treatment of the underlying cause, and regurgitation symptoms usually improve when the underlying cause is cured. Symptomatic treatment is required for the combination of heart failure, dilated cardiomyopathy, and rheumatoid artery disease. For example, heart failure can be controlled by lifestyle modifications such as limiting sodium intake, and if symptoms persist, they can be treated with diuretics such as hydrochlorothiazide and cardiotonic drugs such as digoxin. Tricuspid valve insufficiency without pulmonary hypertension does not require surgical treatment. Tricuspid valve replacement is required in patients with primary leaflet disease. If you suspect tricuspid valve insufficiency, it is recommended that you visit a hospital promptly.
