Cardiac ultrasound mitral regurgitation below 30% is considered mild, greater than 50% is considered severe, tricuspid regurgitation below 20% is considered mild, greater than 40% is considered severe. In general, cardiac ultrasound mitral regurgitation below 30% is mild, 30% to 49% is moderate, and greater than 50% is severe, while tricuspid regurgitation below 20% is mild, 20% to 40% is moderate, and greater than 40% is severe. For patients with mild mitral and tricuspid regurgitation, which does not cause structural changes in the heart, cardiac ultrasound can be reviewed regularly under the guidance of a physician. For patients with moderate or severe mitral or tricuspid regurgitation and severe heart failure symptoms, they can take drugs to improve heart failure under the guidance of doctors, such as metoprolol succinate extended-release tablets, enalapril hydrochlorothiazide tablets, spironolactone and so on, and after anti-heart failure treatment with surgical indications, they can have bicuspid or tricuspid replacement or bicuspid or tricuspid valvuloplasty surgery under the guidance of doctors. Be careful not to take medicines privately, so as not to cause adverse consequences. If you feel unwell, consult a doctor immediately for examination, clarification of the cause of the disease and symptomatic treatment.
