Tricuspid Valve Disease

(Tricuspid Regurgitation; Tricuspid Stenosis)


Tricuspid valve disease refers to damage to the tricuspid heart valve. This valve is located between the atrium (upper chamber) and the ventricle (lower pumping chamber) of the right side of the heart. The tricuspid valve has 3 cusps, or flaps, that control the direction and flow of blood.The 2 main types of tricuspid valve disease are:
  • Tricuspid stenosis—narrowing of the tricuspid valve
  • Tricuspid regurgitation—backflow of blood into the atrium from the ventricle due to improper closing of the tricuspid valve flaps
