What does it mean when an echocardiogram shows tricuspid valve regurgitation?

In general, tricuspid regurgitation shown on cardiac ultrasound refers to incomplete closure of the tricuspid valve—the valve connecting the right atrium and right ventricle—during heart contraction, causing blood to flow backward from the right ventricle into the right atrium. A detailed analysis is as follows:

The tricuspid valve is located between the right ventricle and the right atrium. Tricuspid regurgitation is a type of valvular heart disease, usually caused by either primary valve damage or secondary insufficiency. For example, primary causes include age-related degenerative valvular disease, while secondary causes are commonly associated with conditions that lead to cardiac enlargement, such as chronic obstructive pulmonary disease (COPD).

In addition, if there is mild tricuspid regurgitation, a small amount of venous blood may flow backward. If the degree and progression of tricuspid regurgitation remain mild, surgical treatment or intervention is generally unnecessary. Instead, annual follow-up echocardiography is recommended to assess whether the severity or extent of regurgitation is worsening. However, if regurgitation becomes moderate to severe, surgical intervention on the valve should be considered.

If patients experience any symptoms or discomfort, they are advised to seek timely medical evaluation at a hospital to avoid delays in diagnosis and treatment.
