Tricuspid valve disease is a condition in which the function of the tricuspid valve is impaired.
• The tricuspid valve is located between the two right heart chambers (right ventricle and the right atrium)
• The role of the tricuspid valve is to make sure that blood flows in a forward direction from the right atrium to the ventricle
• Deoxygenated blood comes from the body and fills the right atrium; it then passes to the right ventricle through the tricuspid valve. From the right ventricle, the blood is pumped to the lung to be oxygenated. The tricuspid valve closes to keep the blood from moving backward when the ventricle contracts
• There are several types of tricuspid valve disease, including:
• Tricuspid valve stenosis - a condition in which the tricuspid valve is stiff, thick or fused. This result in a narrowed valve, decreasing the amount of blood that can flow from the right atrium to the right ventricle
• Tricuspid valve regurgitation - a condition in which the valve is leaky or doesn’t close properly, allowing blood to leak backward into the right atrium
• Tricuspid atresia - this is a congenital heart defect in which the tricuspid valve does not form at all but instead a solid sheet of tissue. This tissue prevents blood flow between the right ventricle and the right atrium
CAUSES
Tricuspid valve disease is caused by:
• Infective endocarditis
• Rheumatic fever
• Pulmonary hypertension
• Dilated right ventricle
• Tumors of the heart
• Less common causes include trauma, carcinoid heart disease, systemic lupus, tricuspid valve prolapse
