Tricuspid Valve Repair and Replacement

The tricuspid valve is one of four valves in the heart. It is located between the upper right chamber (right atrium) and lower right chamber (right ventricle). Several types of diseases exist that can affect this valve:

  • Tricuspid valve regurgitation – Occurs when the valve does not close properly, causing blood to flow back into the right atrium.
  • Tricuspid valve stenosis – Occurs when the valve is too narrow, which limits the amount of blood that flows from the right atrium into the right ventricle.
  • Triscuspid atresia – Occurs when the valve is blocked by a wall of tissue, preventing blood from flowing between the two right chambers. This condition is present at birth.

Surgery to treat triscuspid valve problems is unusual by itself, and typically happens in conjunction with surgery to repair or replace the mitral and/or aortic valves. The procedure usually involves a repair of the valve, with the occasional need for replacement surgery.
