    Caval valve implantation for tricuspid regurgitation

    Description

    The tricuspid valve sits between the upper and lower chambers on the right side of the heart. Tricuspid regurgitation happens when the tricuspid valve does not close properly and blood flows the wrong way through it (regurgitation). The blood can also flow back (reflux) into the 2 main veins (caval veins) that bring blood back from the body to the heart. This makes the heart work harder and, if severe, can lead to heart failure. In this procedure, valves made from animal or human tissue (bioprosthetic) are put (implanted) into one or both caval veins through a vein in the groin. This is done without disturbing the tricuspid valve. The aim is to reduce caval reflux and tricuspid regurgitation, improving symptoms of heart failure and quality of life for people who cannot have open heart surgery.
