Tricuspid valve disease is a condition in which the valve between the two right heart chambers (right ventricle and right atrium) doesn't function properly. Tricuspid valve disease often occurs with other heart valve problems.

Several types of tricuspid valve disease exist, including:

  • Tricuspid valve regurgitation. In this condition, the tricuspid valve doesn't close properly, and blood flows back into your heart's upper right chamber (right atrium).
  • Tricuspid valve stenosis. In this condition, the tricuspid valve is narrowed, decreasing the amount of blood that can flow through it from the right atrium to the lower right heart chamber (right ventricle).
  • Tricuspid atresia. In tricuspid atresia — a condition present at birth (congenital) — the tricuspid valve isn't formed, and a solid sheet of tissue blocks the blood flow between your right heart chambers.
  • Ebstein's anomaly. Ebstein's 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).
