Tricuspid regurgitation is not usually self-healing and is an abnormality of the heart valve structure. Tricuspid regurgitation is a condition in which the valve does not close completely when the ventricle contracts, resulting in regurgitation of blood from the right ventricle to the right atrium. Secondary tricuspid regurgitation is often secondary to rheumatic mitral valve disease, congenital cardiovascular disease, and pulmonary heart disease, etc. Generally, tricuspid regurgitation can be relieved by treating the primary disease. In contrast, primary tricuspid regurgitation, including tricuspid valve subluxation, rheumatic tricuspid valve insufficiency, and tricuspid valve prolapse, requires special treatment to recover from tricuspid valve as the primary lesion. Although tricuspid regurgitation is not self-healing, some patients with no obvious clinical symptoms do not require special treatment if they are not combined with other underlying diseases, and regular review of cardiac ultrasound is sufficient.
