Small amounts of asymptomatic tricuspid regurgitation in a 15-year-old boy can be left untreated with regular checkups; if there is a pre-existing condition, it needs to be treated; and progressive worsening of symptoms can be treated with surgery. Mild regurgitation without obvious symptoms and normal pulmonary artery pressure can usually be tolerated without treatment and can be reviewed regularly. Tricuspid regurgitation is usually secondary to congenital pulmonary stenosis, Eisenmenger’s syndrome, and other disorders that result in increased systolic pressure in the right ventricle or pulmonary hypertension, causing tricuspid regurgitation with dilated annulus. If a primary disease is clearly present, the primary disease needs to be treated. Eisenmenger’s syndrome can be treated by sealing the ventricular septal defect. For severe regurgitation with persistently worsening symptoms with right heart dysfunction and no pulmonary hypertension, surgery is not required, but treatment of right heart failure is needed, such as sodium restriction, use of diuretics such as hydrochlorothiazide, and digitalis drugs such as digoxin. If the symptoms of regurgitation persist or worsen progressively, surgical treatment such as annuloplasty and prosthetic valve replacement is feasible. The above drugs need to be used under the guidance of clinicians, unauthorized use of drugs is prohibited; the occurrence of tricuspid regurgitation, it is recommended to go to the hospital in a timely manner.
