Abstract:
Percutaneous implantation of valved stents is now routinely performed to treat pulmonary valve regurgitation and stenosis. In addition, there are isolated reports of implantation of valved stents in the tricuspid position to treat prosthetic tricuspid stenosis or regurgitation when a prosthetic valve ring exists. We present a case in which a patient with combined severe tricuspid valve and pulmonary valve disease was successfully treated with sequential implantation of percutaneous valved stents in a single procedure. The procedure was straightforward, of short duration, and dramatically improved the patient's functional status.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
