Tricuspid regurgitation

Tricuspid insufficiency; Heart valve - tricuspid regurgitation; Valvular disease - tricuspid regurgitation

Blood that flows between different chambers of your heart must pass through a heart valve. These valves open up enough so that blood can flow through. They then close, keeping blood from flowing backward.

The tricuspid valve separates the right lower heart chamber (the right ventricle) from the right upper heart chamber (right atrium).

Tricuspid regurgitation is a disorder in which this valve does not close tight enough. This problem causes blood to flow backward into the right upper heart chamber (atrium) when the right lower heart chamber (ventricle) contracts.

Tricuspid Regurgitation

Tricuspid regurgitation is a disorder involving backflow of blood from the right ventricle to the right atrium during contraction of the right ventricle. It is caused by damage to the tricuspid heart valve or enlargement of the right ventricle.

Tricuspid Regurgitation

Tricuspid regurgitation is a disorder involving backflow of blood from the right ventricle to the right atrium during contraction of the right ventricle. The most common cause of tricuspid regurgitation is not damage to the valve itself but enlargement of the right ventricle, which may be a complication of any disorder that causes right ventricular failure.

Ebstein's anomaly

Ebstein's anomaly is a congenital heart condition which results in an abnormality of the tricuspid valve. In this condition the tricuspid valve is elongated and displaced downward towards the right ventricle. The abnormality causes the tricuspid valve to leak blood backwards into the right atrium.
