Tricuspid valve disease is a heart condition in which the valve between the two right heart chambers (right ventricle and right atrium) doesn't work properly. Tricuspid valve disease often occurs with other heart valve problems.
There are several types of tricuspid valve disease, including:
- Tricuspid valve regurgitation. The tricuspid valve doesn't close properly, and blood flows backward into your heart's upper right chamber (right atrium).
- Tricuspid valve stenosis. The tricuspid valve is narrowed, reducing the flow of blood from the right upper heart chamber (right atrium) to the lower right heart chamber (right ventricle).
- Tricuspid atresia. In this condition present at birth (congenital heart defect), the tricuspid valve isn't formed. A solid sheet of tissue blocks the blood flow between your right heart chambers.
- Ebstein anomaly. Ebstein anomaly is a congenital heart defect in which a malformed tricuspid valve sits lower than normal in the right ventricle. This can cause blood to flow back into the right atrium (tricuspid valve regurgitation).
